Resolution of touch in Shape changing display

This study was conducted as part of course on Human Computer Interaction. We were just getting introduced to how HCI research is done in real world.

For this work we created pin based shapes using Laser cutter at different resolutions and we asked users to feel the shapes by touching. We digitalised the touch responses and tried to conclude on the touch sensitivity of the set of our users.

The study can be found here.

This study is useful for contexts where we are trying to add tactile feedback to touch devices. Example a work from MIT based on haptic touch display.
