In our everyday life, the perception of thermal cues plays a crucial role for the identification and discrimination of materials. When touching an object, the change of temperature in the skin of our fingertips is characteristic for the touched material and can help to discriminate objects with the same texture or hardness. However, this useful perceptual channel is disregarded for interactive elements on standard touchscreens.In this paper, we present a study in which we compared the rate of object discrimination for stand-alone thermal stimuli as well as supplemental thermal stimuli characterizing virtual materials on a touchscreen. Our results show that five materials could be discriminated at a stable rate using either stand-alone or supplemental thermal stimuli. They suggest that thermal cues can enable material discrimination on touch surfaces, which gives way for expanded use of thermal stimuli on interactive surfaces.

“…Other recent papers show the potential of remote tactile feedback to create novel forms of haptic stimuli by combining different types of actuators (e.g., vibrotactile and linear moving) on the body. A haptic armrest was used to communicate tactile surface characteristics and forms of buttons on touch surfaces [26]. Users indicated the high hedonic and pragmatic quality of the created stimuli.…”

Abstract. Tactile feedback on touch surfaces has shown to greatly improve the interaction in quantitative and qualitative metrics. Recently, researchers have assessed the notion of remote tactile feedback, i.e., the spatial separation of touch input and resulting tactile output on the user's body. This approach has the potential to simplify the use of tactile feedback with arbitrary touch devices and allows the design of novel tactile stimuli by stimulus combination. However, a formal comparison of direct and remote tactile feedback during touch input is still missing. Therefore, we conducted three consecutive laboratory studies. First, we compared the effects of both direct and remote tactile stimuli on the user's performance during touchscreen interactions. No difference was found in the positive effects of both types of feedback. Second, we evaluated the impact of the remote tactile actuator's position on the user's body. For remote tactile stimuli, we found improved accuracy and interaction speed, regardless of the body location. Third we analyzed remote tactile feedback under additional cognitive load. The results support the positive effects of tactile feedback on user performance and subjective evaluation. These findings encourage us to further exploit the potential of remote tactile feedback to simplify and expand the multimodal interaction with arbitrary touch interfaces.
