C. Rendl, P. Greindl, K. Probst, M. Behrens, M. Haller - Presstures: Exploring Pressure-Sensitive Multi-Touch Gestures on Trackpads - CHI '14 CHI Conference on Human Factors in Computing Systems, Toronto, ON, Canada, Canada, 2014, pp. 431-434
In this paper, we present Presstures, an extension to current multi-touch operations that enriches common multi-finger gestures with pressure information. By using the initially applied pressure level for implicit mode switching, a gesture
can be enhanced with different functionalities to enlarge the interaction space for multi-touch. To evaluate the feasibility of our concept, we conducted an experiment, which indicates good human sensorimotor skills for performing multi-touch gestures with a few number of pressure levels and without any additional feedback. Based on the experimental results, we discuss implications for the design of pressure-sensitive multi-touch gestures, and propose application scenarios that make optimal use of our concept.
