A temerature-based touch-sensor for non-emissive textile displays

Abstract

Non-light-emissive textile displays have become a popular research area that allows subtle and ambient animations on our textiles. This work explores one such existing technology which uses thermochromic inks and peltier semiconductors to implement touch sensitive non-light-emissive textile display. To achieve this we investigate a new method that detects temperature transients (caused by a touch) in order to detect a touch which allows interactive touch sensitive textile displays without any changes to the existing hardware.
