Tangible 3D haptics on touch surfaces: virtual compliance

Suitability of current haptic three-dimensional user interface (3D-UI) technologies is low for mobile interaction. 3D-Press in reviewed in this paper: a technique to create the haptic illusion that when pressing on a rigid surface is feels compliant. The fact that the illusion is intramodal (haptics only involved in creating it), and that the technology required is simple and with low energy demands, makes it ideal for mobile use. The parameters used in the implementation of 3D-Press influence the characteristics of the illusion. A research agenda is proposed to understand this relationship, as well as to learn how to integrate 3D-Press in multimodal interfaces for constantly-changing mobile use contexts.
