PVA Ideas

I wanted to think of different ideas to use PVA in different contexts, I found that this was quite a hard thing to think off, I knew that it was food safe but should avoid swallowing the compound.
I came across this cool Idea called Moss Graffiti where you use moss to crate an organic may to crate Art on a space. I thought that if people didn't like it they could just spray it down and it would wash away so I thought you could use this concept with PVA and you could find away you make graffiti with it and over time the PVA wold dissolve with the rain water and wash away therefore it would per permeant and the space could be used for something else.

 The problem that I would find with PVA is the look of it, the reason why I found the moss graffiti so intriguing was the fact that it was an organic art form and it uses both human and nature to crate it, while if you did the same with PVA it is only human input. it also would look as visually appealing being the colour and texture it is, you would have to come up with a way to make it different colours and to not make it so sticky when it is racing with the water.

 

Polyvinyl Alcohol.

For this assignment was have to experiment with the chemical compound of Polyvinyl Alcohol (PVA) A colourless, water-soluble synthetic resin. 
To see how it worked I wanted to see its featuers in action:

Polyvinyl Alcohol

First I wanted to see how long it took for PVA to dissolve in water. I cut a small piece (less then 1cm squared) and placed it into a small dish of distilled water, I thought it wouldn't take very long for the reaction to occur, but in the first five minutes nothing happened I even tried moving the water around to make the reaction work faster but it still didn't dissolve, but when touching it, it was no longer smooth and hard but more flexible and slightly sticky and gluey. I then left it for three hours and came bak and it had finally dissolved and made the water no longer clear but a milky colour and then over night the water then separated and the PVA had fallen to the bottom and settled.

over night the PVA had separated from the water

The next Idea I wanted to look in to was to see if I could get the PVA to work into a paste by only using a little about of water. After time the PVA did dissolve into the limited amount of water making it  into a sticky and gluey texture but it still held its form and was not forming a paste. Over night the water  evaporated from the PVA resulting in the PVA that had dissolved into the water to harden back into the solid state, but in a thiner form. I found this pro sees rather interesting as you could use this concept to make the PVA into different forms and thicknesses by evaporating the water.

over night after water had evaporated

Next I wanted to see if PVA was soluble in other liquids, the two I tried was oil and salt water, I put the same sized piece of PVA that I put into the water to see if in the same time frame would anything happen. I have had the PVA in the solutions for three days now and no reaction has started to occur. this then proves that PVA is not soluble in salt water or oil. this could help in my design as I know how to prevent the reaction if I don't want the reaction to happen for some reason.

I had also heard that PVA burns like paper, I would of really liked to try this but I don't own matches or a lighter, but I think it was some good inside to know that PVA is flammable. When I get my hands on a lighter I will give it a try.

Comfort and tying your shoelaces

From research it is suggested that there are two different types of comfort, psychological and physical. "Comfort is a pleasant state of psychological and physical harmony between a human being and his or her environment" (Slater, 1985). Psychological is where you are comfortable with the surrounding mentally, you feel reassured and safe; it plays off your memories, trust and relationships. This type of comfort takes a long time to create and is studied a lot with nurse where they try to create an environment for a patient to feel comfortable. Comfort with nurses is described ‘that comfort is the overall role that nurses have to focus on and to achieve this they have to first identify patients’ perceptions of their needs’ (Orlando, 1961), it is also the process to developing a close relationship with the patient which can result in healing and growth (Hall, 1964). A study by Elizabeth Tutton (2004) outlined how nurses perceive comfort and how they create comfort for their patients, the study showed that comfort was an individual process in which every one is different, and the staff needed to find out the patients wants and wishes to fulfill them. It was found that the patients felt more comfortable when the nurses had more positive attributes such as; kindness, gentleness, goodness and friendliness. It was found that comfort was also created when the nurse knows the patient, their background, likes and dislikes and simple facts about them, as this created a sense of normality.

Physical comfort is identified where you feel comfortable from and physical product or service. This type of comfort is taken for granted as people only feel comfortable after discomfort (Farrell, 2009) and this comfort is only temporary and last a short amount of time. I understand that this comfort only last for the length of the kinetic movement such as rubbing a soft surface, once you have stopped rubbing the soft surface the comfortable sensation stops. Physical comfort is integrated in industrial design with projects such as creating a chair that is comfortable, rather than an uncomfortable chair. “There are at least three design issues that need consideration in striving for comfort; Firstly, the exact cause of discomfort or comfort is unknown; there is no model available that describes the cause of comfort. Secondly, every individual has his or her own meaning of comfort, as it is a subjective phenomenon. Thridly, the comfort design process is not described and the approach is unknown" (Vink, 2005).

When considering comfort, Looze et al. (2003) described that there were three manifestations for considering: "Discomfort: the participant experiences discomfort because of physical disturbances in the environment. No discomfort: the participant is not aware of discomfort or comfort or there is no discomfort. Comfort: the participant experiences noticeably more comfort than expected and feels comfortable."  Looze et al, (2003:p 990) .The model explains the different factors that interact on resulting the design of the object, creating different manifestations; it described that you not only had to feel physically comfortable but other factors acted influence this, such as temperature, humidity, noise, state of the person, history and smell. "The history of our comfort experiences determines our expectations of a product based on what we are used to" (Looze et al. 2003: p991) this links to the physiological aspects of comfort and person memories. A study by Zhang et al. (1996) found that the absence of discomfort did not result in comfort. It showed that discomfort was associated with pain and if that was taken away then nothing was experienced, while comfort is related to the sense of well being and the pleasure the chair gives; discomfort highlights more physical aspects, such as pain, ache, hurting while comfort shows more of the mental aspects such as feeling happy, relaxed, safe, calm and restful. 

My interpretation with regard to these two different two types of comfort is the concept of time; as it takes a long time to create a safe, relaxed, comfortable environment to generate the sensation of mental comfort. Where as, physical comfort only lasts a few seconds, and when you stop moving, smelling  or listening to the experience of physical comfort, you then lose the focus on comfort and will then only consider comfort again when the action or product is deemed uncomfortable. The factor of time then becomes a big issue of making the experiment, as you have to allow for time to create both mental and physical comfort. 

A theory was devised; it was important to have two parts of the experience. As humans, we take the physical aspects of comfort for granted and because of this it is not practical to create physical comfort only to try to prevent physical discomfort. Preventing physical discomfort will act as a catalyst to creating physiological comfort. Making a comfortable environment using memories, safety, relaxation and positive attributes will create physiological comfort.

I wanted to make an experience to represent the actions of putting on and tying your shoes in a comfortable way. I feel that comfort is simple but meaningful, it’s a feel that you don't want to over power as then I feel it loses its meaning, so I wanted an experience that doesn’t have too many gadgets.

Initially I created an environment to prevent physical discomfort by using soft fabrics and textures such as fur, satin and having soft padding in the shoe. I enlarged the action of tying your shoes to emphasize what is being done; I still wanted to keep it in the feet region. I feel that is a main part of the act of putting on your shoes is the bending down so there is that connection will use your whole body.  I wanted this part of my experience to show a large amount of comfort, as I feel I there is more of a physical comfort rather then a mental comfort to tying up your shoes (and mostly touch) In making this I used soft materials, two soft pieces of padding were sewn together that can be laced up, this covered the whole leg making the experience more enlarged. These soft materials prevented an uncomfortable experience physically and also manipulated the actions on tying up your shoes. Also lined the bottom with a soft fur fabric to create physical comfort and it also created a warm environment inside that helped to make it more psychologically comfortable.

To create physiological comfort I will look at smell, the visual look of the experience and the way I act when presenting it. Vink (2005) reported that even though we are mostly not aware of the effect that smell has on us with comfort it actually influences our experiences. Therefore smell can trigger past memories and if the memory is comforting it can stimulate the feeling. Personally the smell of lavender is comforting so I used the aroma on the object to help stimulate the physiological sense of comfort. Another physiological comfort factor is the visual look of the object; this plays on the idea on memory and history with other objects. I felt an object looks comfortable with the shapes the form creates, soft, fluid, rounded shapes and also the colours used. As I was trying to keep the model simple and not over powering I made the whole model pure white and used soft fluid fabrics to make it so it looks comfortable before sitting on it and using it. Nurses fundamentally use comfort as part of their professional work, I wanted to try and use their type of personality of make the experience more mentally comfortable being; friendly, gentle and kind. Time is also an important factor of comfort, for this the experiment was kept short and simple as I felt that the user would start loosing the comfortable feeling if it kept going for too long, so it only lasted about two minutes.

The design.

I want to make an experience to represent the actions of putting on and tying your shoes in a comfortable way. I feel that comfort is simple but meaningful, its a feel that you don't want to over power as then i feel it loses its meaning, so I want an experence that dosent have to many gadgets.

•  my first part is to enlarge the action of tying your shoes to emphasize what is being done, I still want to keep it in the feet region as I fell that a main part of the act of putting on your shoes is the bending down so there is that connection will using your whole body. really wanted this part of my experience to show a large amount of comfort, as I feel i there is more of a physical connection rather then a mental connection to tying up your shoes (and mostly touch) I wanted to have a stronger connection with the prevention of physical discomfort in this part of the experience. in making this I will use soft materials, two soft paddings sewn tougher that can be laced up, this would cover the whole leg making the experience more enlarged, to make this I will make it from two pillows and three pillowcase all sewn together, two of the cases will hold the pillows and the other will act as the tongue will large satin ribbon to tie it up. all of these soft materials will prevent an uncomfortable experience physically and also manipulate the actions on tying up your shoes. I will also line the bottom of the incasing with a soft fur fabric the will create an initial physical comfort and it also create a warm environment inside the helps to make it more comfortable
• when tying up your shoes you normally sit down, so I feel that the sitting down part of the experience is quite important, to prevent discomfort i will have the chair ergonomically comfortable  with the average sitting hight for the average sized person, to prevent pain and ache. I will also add padding to the chair to had even more support. the touch, warmth and ergonomics are all used to prevent physical discomfort. 
• To create physiological comfort I will look at smell, the visual look of the experience and the way I act when presenting it. in one of the reading I found it explained that smell was a good way to crate comfort as it can trigger past memories and if a comforting memory will stimulate the feeling, I wanted to use this Idea as I personally find that the smell of lavender is a comforting smell, So I will cover the object in lavender oil to crate the memory. 
• another physiological comfort factor is the visual look of the object, this plays on the idea on memory and history with other objects. I feel an object looks comfortable with the shapes the form creates, soft, fluid, rounded shapes and also the colours used, my personal preference on comforting colours are warm colours such as yellow, orange and white. as I am trying to keep the model simple and not over powering so I feel I will make the whole model pure white and will use soft fluid fabrics to make it so it looks comfortable before sitting on it and using it. 
• when looking at how nurses use comfort, it is in their actions, even though it is over a long period of time for them to create their time of comforting actions to their patients i want to try and use their type of personality of make the experience more mentally comfortable; friendly, gentle, kind and friendly.
• time is also a factor that I feel it a big part of comfort, I want to keep it short and simple as we take comfort for granted I feel that the user would start loosing the comfortable feeling it I keep it going for to long, so it should only last about 2 minutes.

comfortabel experience

After doing readings on both psychological and physical comfort and looking at the difference of comfort and discomfort I found that the psychological accept played a more fundamental part of creating comfort then a physical object, as it was easier to determine wether an object was my physically uncomfortable or not uncomfortable rather then determining if it was comfortable due to comfort being a subjective phenomenon (Vink, 2005) and also we take physical comfort for granted as physical comfort is stronger after discomfort (Farrell, 2009).

There are two parts I want to portray in my experience

First I want to create an environment to prevent discomfort physically, such as;

• Using soft fabrics and textures such as fur, or satin and having soft padding that works ergonomically. Also colours that are deemed warm like orange, white or yellow
•  a warm environment with temperature and and humidity. 
• Also prevent pain, ache, numb hurting and other discomfort sensations. 
• consider the ergonomics and posture to the experience, will they be standing or sitting, will it have support or not?

second I want the experience to be psychologically comfortable;

• use a smell that will bring comfort in the use of memory and history, I personaly see the smell of lavander as comforting as I relate lavender with going to sleep, when I couldn't sleep when I was a kid my mother used to rub lavender on my chest and wrist to help me relax, so now when I smell it I relaxed which I fell is a sense of being comfortable. 
• create a safe, relaxing, calm and restful environment 
• when presenting show positive attributes of, kindness, gentleness, goodness and friendliness
• think about the history behind peoples experiences of putting on shoes and use the idea of memory to create a comfortable environment 

I feel that it is important to have two parts of the experience, my theory is that you can't create physical comfort only try to prevent physical discomfort as we as humans take the physical aspects of comfort for granted. so preventing physical discomfort will only act as a catalyst to creating physiological comfort, this will then be created by making a comfortable environment using memories, safety, relaxation and positive attributes. 

Comfort

From doing readings I found that there are two different types of comfort mental and physical. mental is where you are comfortable with the sorundings mentally, you feel  reassured and safe, it plays off your memories, trust and relationships. This type of comfort takes a long time to create and is studied a lot with nurse where they try to create an environment for a patient to feel comfortable. while physical is where for feel comfortable from and physical product or service this type of comfort is taken for granted as people only feel comfortable after discomfort and this comfort is only temporary and last a short amount of time, I feel that it only last the length of the kinetic movement such as rubbing a soft surface, once you have stopped rubbing it and just leave you hand on the surface you no longer feel the comfortable sensation, this style of comfort is used in industrial design, such as chair making where you are not trying to create comfort but prevent discomfort.

I feel that the main difference between these two types of comfort is time as mental comfort takes a long time to create a comfortable environment I feel would take a few days to create the mentally comfortable environment while physical comfort only lasts a few seconds as when you stop moving/smelling/listening you lose the focus on comfort and will then only consider comfort again when the the action or product is deemed uncomfortable. the factor of time then becomes a big issue of making my experiment as you have to get the time just right to try to create mental and physical comfort.


Physical Comfort:

Vink, P. (2005). Comfort and design: Principles and good practice. Boca Raton: CRC Press.

To get a better under standing on physical comfort I read a book by Peter Vink- Comfort and Design.
it book when into great detail on the principles to create a comfortable chair and environment. Vink described comfort as 'freedom from pain; well being', there is at least three problems face us in striving for comfort; 1. the exact cause of discomfort or comfort is unknown, there is no model available that describes the cause of comfort. 2. every individual has his or her own meaning of comfort. comfort is a subjective phenomenon. 3. the comfort design process is not described and the approach is unknown." and 'the product its self can never be comfortable; it becomes comfortable (or not) in its use." This then shows that it is difficult to create an environment or product that is deemed comfortable to ever user. Vink looked into a study by Slater (1985) who "defines comfort as a pleasant state of physiological, psychological and physical harmony between a human being and his or her environment "this shows that for product and physical comfort we also have to factor in the mental aspects of comfort it was also stated "the history of our comfort experiences determines our expectations of a product based on what we are used to" (looze et al. 2003 (comfort and design) which relates back to the physiological aspects of comfort and how it relates back to memory. Vink also described that there was three manifestations when considering making comfort;
"Discomfort- the participant experiences discomfort because of physical disturbances in the environment.
No discomfort- the participant is not aware of discomfort or comfort or there is no discomfort.
Comfort- the participant experiences noticeably more comfort than expected and feels comfortable."
when trying to consider where the user would lie with the different manifestations when using the product Looze et al. (2003) created a model to show the different factors that can action on resulting in the different manifestations;

it described that you not only had to physically feel comfortable but other factors acted on it such as temperature, humidity, noise, state of the person, history and smell, it was reported that even though we are mostly not aware of the effect that smell has on us with comfort it actually influences our experiences. 

The book went into detail on the comfort and discomfort specific to seating and how people experienced comfort in their seats, studies where found that the absence of discomfort did not result in comfort. it showed that discomfort was associated with pain and if that was taken away then nothing was experienced, while comfort is retaliated to the sense of well-being and the pleaser the chair gives; 

discomfort highlights more physical aspects, such as pain, ache, hurting while comfort shows more of the mental aspects happy, relaxed safe, calm and restful.

Vinks Theory on comfort changed my views on Physical Comfort, even though I know it is hard to create a physical object that is deemed comfortable in the sense of touch as comfort is a Subjective experience I can try to create an experience that could create an experience that results in safety, restfulness, happiness and being relaxed with a physical object it will result in the objects making a comfortable experience. 


Physiological comfort:
 I found that it is very difficult trying to find information on psychological comfort that can be related to design. I found that there is research that has been done with in nurses to help create a comforting environment for their patients, I felt that this could help to relate to the design world. it was described that comfort is the overall role that nurses have to focus on and to achive this they have to first identify patients’ perceptions of their needs (Orlando, 1961). it is also the process to developing a close relationship with the patient which can result in healing and growth (hall, 1964). 

I found a study buy Elizabeth Tutton who looked it to the relationship between elderly people and their nurses in a ward and try to make it more comfortable for them. (Tutton, E., & Seers, K. (2004). Comfort on a ward for older people. Journal of Advanced Nursing, 46(4), 380-389. doi:10.1111/j.1365-2648.2004.03005.x)  As a whole didnt relate on what I was trying to find out about physiological comfort but it give some good insight on how nurse perceive comfort and how they create comfort for their patients, The study showed that comfort was an individual process in which every one is different, and staff find out the patients wants and wishes and tries to fulfill them. it was found that the patients felt more comfortable when the nurses had more positive attributes such as; kindness, gentleness, goodness and friendliness. if was found that comfort was also created when the nurse know the patient, their background, likes and dislikes and simple facts about them, this was because knowing the person created a sense of normality and community. The environment provided is also deemed as an important factor in creating comfort, as the patients are in the ward for a long period of time they have to create a space which is welcoming and personal, we the patient can have their own space. comfort is also created in every day activities such as helping to wash someones hair or cutting their nails, also helping assist them in knowing what is happening like providing a mirror so they can see their injuries heal.
this studied show the long term ways to create a comfortable environment and playing on the physiological aspects on comfort, even though I don't have the time to lean the background to the tutors and find out their likes and dislikes and base this experience over the space of a few weeks caring for them and providing their wants and wishes, I could use some of the concepts of what nurses use to create comfort an make a lot shorter experience.
