Emo-Wearable
We developed a haptic elastomeric affective device for material perception research experiment. Particularly, we will explore a pneumatically actuated
haptic wearable device composed of a soft silicone to provide a diverse spectrum of tactile stimuli by leveraging kinesthetic cues from force-feedback
silicon actuators that push against the user’s body. After identifying multiple elastomer actuation behaviors and analysis of emotional response, we hope
to conduct a study that could be potentially used for delivering the dynamic change in human emotions in remote/immersive environments i.e.AR/VR.

Actuation
Participant went through total four rounds of experiment. each round included a survey and a different actuation behaviors. For exam- ple, bubble 1 was inflated for only 5s and bubble 2 was inflated for 10s, resulting in over inflation of Bubble 2. We also explored how the number of legs (specifically four legs and two legs) place on a participant arm changes the emotional responses.
