We work with industry, ophthalmologists and representatives of the visually-impaired community to investigate the sense of touch as a potential substitute for sight. Towards this aim, we ask:

The outcomes of our research will be used to design interface for smartphones and tablets that can support how visually-impaired people use mobile technology to interface the digital world.

Latest outcomes:

Can volunteers feel “virtual textures” on next- generation haptic technology? In collaboration with TANVAS, we measured blind and sighted volunteers’ ability to “feel” virtual grating patterns on the touchscreen. Like vision, we found that all volunteers were most sensitive when the gratings were of medium width (compared to very narrow or very wide gratings). Interestingly, blind and sighted volunteers had the highest sensitivity to different widths; and sighted volunteers generally had higher tactile sensitivity. Click here for a poster.

About Us

We aim to provide a better interface to the digital world for those who are visually impaired by using next-generation haptic feedback technology for smartphones and smartphones.
