TCieX: An Approach toward Communicating Weight through Pseudo-Haptic Feedback Mechanisms


The notion of weight is useful to represent not only the mass of an object, but also the physical feedback for a remote interaction as well as the importance of a concept. Existing human-computer interaction design has communicated weight primarily through the three means: symbolic representation ("240g"), kinesthetic interaction (by wearing a physical actuator), and haptic feedback (by applying low-frequency stimuli to the forearm). Our approach uses a fourth means that uses the visual and audio interaction to communicate weight, stiffness, or viscosity through pseudo-haptic feedback mechanisms. Pseudo-haptic feedback stimulates haptic sensations without using a haptic interface but using dynamically changing visual and audio representations in terms of the hand movement. We have built TCieX (Touch-Centric interaction embodiment eXploratorium) as a collection of interaction test suites, with which a user produces a variety of combinations of temporal, visual, and auditory representations for different types of simple object movement through different C/D (Control/Display) ratios and mapping profiles. By using TCieX, an interaction designer explores a design space of visual and auditory representations to produce a desired effect of pseudo-haptic sensations.
