ThermoSurf: Thermal Display Technology for Dynamic and Multi-Finger Interactions

Thermal feedback has been proven to enhance user experience in human-machine interactions. Yet state-of-the-art thermal technology focused on the single finger or palm static contact, overlooking dynamic and multi-finger The underlying challenges include incompatible designs of conventional interfaces for providing salient stimuli such interactions and, thereby, a lack knowledge human perception relevant conditions. Here we present ThermoSurf, new display that can deliver temperature patterns large interface suitable We also investigate how exploration affects generated distributions. Twenty-three participants interacted with device following three conditions: static-single finger, dynamic-single static-multi finger. In these experiments, individuals evaluated 15 differences ranging from −7.5°C +1.5°C an initial 38°C. Our results showed sensitivity against is significantly greater contact compared other tested addition, this interaction type resulted higher discrimination thresholds than ones reported literature. findings offer perspectives consistent future tactile interfaces.
