Magic Lining at Universidad Carlos III de Madrid: week 2

February 6, 2018

The Magic Lining team started the week by developing a 3x7 matrix structure of the vibrating textile, that would allow them to play with the different vibration patterns on the body. They placed the motors more separately than in the single line prototype, as they found out from the previous literature on the sensitivity on the arms and back that people could not distinguish the stimuli with the shorter distance.

 

After solving several technical issues in programming the Arduino and connecting electronics, they could start looking deeper into the vibration patterns and behaviours. The team looked up experimental work from the neuroscientific papers (Deroy, 2016; Amemiya, 2013) to understand how the vibration has been used on the body before and what kind of patterns people have worked with and the typed of results /conclusions they have drawn from the experiments. They looked at the intervals between the different motors and the duration of the vibration.

After trying out the 3x7 prototype on the different parts of their own body, and in different directions and movements the team started to think about collecting some data from a user study in order to get a more neutral opinion about the vibration movements on the body. The conditions with the greatest potential according to the initial tryouts on the team members were the following (see video):

- a wave from the fingers to the upper arm

- a wave from the upper arm to the fingers
- a wave moving vertically from the center of the back towards the upper and lower back
- a wave moving vertically from the upper and lower back towards the center of the back

- a wave moving horizontally from the center of the back towards the sides of the back

- a wave moving horizontally from the sides of the back towards the center of the back

For the user testing the team changed the looks and feel of the prototype towards a more finalized one and developed a questionnaire  based on the neuroscience papers. In the questionnaire the participants report about the different bodily sensations they experience before the sessions and after experiencing each pattern on their body. They enquire the users wether the different vibrations made them feel quicker, slower, heavier, lighter, stiffer, more flexible, harder, softer and so on. The questionnaire creates a starting point to understand wether the vibrations can affect the way people feel about their environment or their own body composition (e.g. wood, water, rocks etc.).

On 21st of December Kristi gave a talk about her previous work and the current Vertigo project for the DEI Interactive Systems Group and external visitors. The talk was followed by a discussion and a pizza lunch. Several paths for the future were explored with the group.
