envella Final project implementation

In this paper we describe enVella, a kinetic dress with movement triggered by the detection of the wearer’s fear or anxiety. The upper portion of the dress is surrounded with fans which open and envelope the wearer if her body temperature and heart rate are both rising. The aim of this project was to investigate the detection of fear with biosensors, and to see whether an enveloping physical transformation can provide a sense of comfort to the user. We begin by going over background research we conducted. Then we describe our prototyping process and challenges we faced along the way. We describe our implementation details, user reports, and then conclude with a discussion of future.

Material:
Chocolate satin silk material in conjunction of interface to make a material that is flexible enough to handle yet ridget enough to fan out without collapsing.

Technical:
Heartbeat sensor:  Increase in anxiety will increase in heartrate and tempurature, this is one of the result we concluded after we research into this area. So we bought a special heartbeat sensor that work with arduino called “HRMI” with polar band to detect user’s heartbeat.

Tempurature sensor are use to detect changes in body tempurature, however we later found out our human body tempurature does not fluxuate that much as a result it will be a challange for us to map this chabge.

Prototype:
Earlier the week we tried various idea that would give user the experience of enveloping and explore our research topic “perception of safety” , our single track system did not work out the way we want due to lack of equipment in school that allow us to bent the tube into a more organic shape that we desire.  As a result we implemented multiple fan at different location of the body which opens up in sequence once it triggers by the heart rate sensor,

We made paper prototype of the fan structure which later on going made into fabric using double sided fusible web interface with two fabric sandwich it in between to gave us the material that we want.

To make the crease we use iron to each and every fold inside of using laser, we found this method to be more effective. The fan structure it self has two wooden backing to give further structure integrety.

It was a challange to sow all servo motor or any support backing material on the manikin because it doesn’t give us alot of room, but the manikin allow us to accurately plot where each actuator will go.

Over asthetic is achieve by having similiar type of chocolate brown satin silk material that made into a lace like dress that cover the overall manikin.. this give our project more consistency and continuous rather then each fan looks like seperate element.

User testing:::
Due to time constraint we only had two user testing, they both feel the dress is not too cumbersome and nor heavy. However, if the heartbeat sensor can be more accurate it would be ideal, since one of the challages we found is with the detecting with increase in heart rate, there would be a delay before the fan opens.

 

Future plan:::

Instead of using rectangular fan perhaps we can use more rounded shape structure to make it more integreted with the overall look

320: Final Project 4th Meeting (Second week)

The team sat down and re ask the questions like starting all over again from zero. We asked: what does safety mean to us? One good point is that we are people that behave in a human being way. It is very difficult for our wearable to communicate to the user if the message is based on animal experience, not human experience. If a piece of work doesn’t relate or connect with the user, it has no meaning and purpose. In stead of trying to implement animal characteristics to the wearable, the team decided to do something related to people. A quality of feeling safe for people is the idea of being hugged and being protected since young by mom. One very intuitive, implanted idea is the feeling of being inside a womb. We did some simple tests to some friends and ask them for some feedbacks about being circled by a materials around the neck and the torso. The purpose of these tests is to investigate if that sense of feeling safe inside a wrapped around area portray a sense of comfort and safety to people. Through many iterations and pages of sketches, we developed couple dress that the form itself will transform according to the heart rate input. The gesture of being wrapped, surrounded and covered in a dangerous situation.

320: Final Project 3rd Meeting

In class critique.

After presenting our current spine idea in class, the team feels that there is a need to think the idea and concept over. The comments are that there are too many elements and great ideas but without a cohesive overarching idea that envelope the design. We need to ground the idea before we re develop the form once again. We decided the team into two sub groups again. Mark and Laurence will focus on the two sensors that the team decided to use after the conceptual research component. When a person feels fear, not only do they increase in heartrate but also suffers other biological change – ie. sweating. Emily and I went into more sketches boarding to develop more forms that will be suitable for our new idea. Also, to analyze all the comments we got from the critique and rethink our current approach.

320: Final Project 2nd Meeting

During the second meeting, each person came to the meeting with some insights and discoveries in regards to the defence mechanism in animal instincts. We found that there are few different types of defence that different animals have, each with its unique form and execution. The porcupine curls its body into a ball shape in a dangerous situation. Some squids will quirt ink to blind their predators. The poisonous pufferfish will engulf water and increases its size enormously. All these transformations help the animal to better survive from being attacked or eaten by predators. The team asked if these mechanism holds opportunities to be translated into a wearable garment. At the end, we took elements that we enjoyed from our previous sketch two and tried to add more elements to this final project. Once we’ve came into conclusion on what we are heading to, we’ve conducted an informal discussion with an instructor in hopes for some advices and guidances.

After the discussion, we digested the instructor’s comment and are trying to “adapt” to a completely different, yet interesting form suggested by the instructor. The form still contains elements from the previous sketch, but a new spine structure is being added to the back, like a scorpio. Not only did we discuss and explore on the spine structure during the meeting but also brainstorm in some possible interesting materials to be used for this spine structure. There is a question derived from our proposed context – if the user wears the garment in the dark, how can the attacker or anyone be able to see the movement in such a dark environment? Maybe, lights can be implemented into the structure. In order for the lights to work in a subtle manner, the structure should not be intrusive in the morning, but only when the dangerous situation arise. At the end, we were encouraged to play around with the structure using clear, transparent plastic films.

As soon as we’ve dismissed the meeting with the instructor, everyone in the team quickly got together and tried to unify on a solid concept that will fit the form. I took the clear material and tried to prototype the simple spine structure in order to better visualize the idea for the team. It took many sketching, thinking and iterations to develop an sequence of spine sections that will give subtle, flexible movements.

320: Final Project 1st Meeting

Concept: Defence wear

The team has taken inspiration from the sketch two and are passionate about further developing the spine like structure. With the joining of new members: Mark Coleman and Alice Ling.

We liked to incorporate their idea of using the wearer’s heartrate as input and execute the transformation through kinetic movements. Instead of using linear origami arrangements, the team decided to explore the 3D origami shoulder piece and hope to use this as the main elements and supporting structure for the final project. One challenge we faced is the rigidity of the paper. We were unsure if the paper structure actually allow large movements and be able to provide hosting areas for the technical components to rest on. After consents, the team is divided into two sub groups. Emily and Alice are responsible for the conceptual research where the form should be based on a strong metaphorical animal to reference of. Laurence, Mark and I are responsible for all the technical aspects including the use of heartrate sensors and the materials.

320: Day 3

On Day 2, we built a frame structure for our dress, however due to implementation issue and time constraint we had to change the design

Reconfigure of design. The frame now wrap around the user’s head. It add a sense of security. However the bulkyness of frame seem rather cumbersom at times.
We are testing the paper mechanism to see how it fit with the frame. Alot of prototyping involve.

Process shot during our implementation process. Our team had to design part of the frame test it and redesign again because placment of motor and curvature of the frame is really important in our case.

Fabrication of the final product. We laser cut paper to ensure motor fit into place.  Another problem we encounter was the movment of the structure was not pronounce. In the final sketch we be able fix this issue.  The reason that cause movment of the paper has alot of factors. Such as, the fold of the paper, number of modular pieces and the dexterity of paper.
We tried 3 different type of paper: A4 paper, Japanese origami paper and tracing paper. During our material exploration we found out tracing paper was give the least resistant movment however the over integrity of the structure is decrease.


Final context shot.

320: second day

Our goal today was to create the dress.  One problem we encounter was how to fixate the servo motor on the belt, inorder to solve this problem, we created our second mock up protype to test our initial frame work.

Our mock up.  We decided to use two frame structure because there is a motor placement issue.

We decided to do a ring structure frame work to hold the dress.  [sketches and pictures of this structure will be updated later]
