Do you love horror movies but hate watching it alone?

Inspiration

Inspired by the notion of creating enchanting interaction and the Good Night Lamp Project, we brainstormed how we can allow people to communicate different messages through haptics. We wanted the object to be something that creates intimate connection and nonintrusive.

Conceptual Design:

We modelled this device after the interaction of squeezing someone’s arm during the scary part of a movie for reassurance.

The device uses pressure sensors and haptics to help couples feel closer to each other by communicating the emotions they are experiencing while watching a horror movie.

The person who is feeling scared will grip the arms of their hugging pillow, triggering the pressure sensors. The haptics on the other person’s pillow will vibrate lightly to let them know their friend or lover is scared.
