What is interesting about this device is that, because its elastic qualities, it applies natural force feedback to the user’s hands when it is bent. This is complemented with active haptic feedback, shown in the video as sound, but actually meant to be felt with the fingers. The haptic feedback in this device is much more than the simple vibration in most mobile phones, instead, ReFlex is capable of providing complex haptic textures that emulate the physical features of a variety of materials.
ReFlex was the subject of a research paper published this week in the 10th ACM Conference on Tangible, Embedded and Embodied Interaction (TEI) in Eindhoven, The Netherlands:
