Engineering Touchscreen Input for 3-Way Displays: Taxonomy, Datasets, and Classification
Jean M. Vanderdonckt, Radu-Daniel Vatavu, Arthur Sluÿters · 2024
In the family of personal multi-display devices and environments, 3-way displays conveniently integrate into the conventional form factors of laptops and tablets, featuring both a central display area and two symmetrically expandable lateral sides. However, despite a large body of knowledge on touch input for single-display devices, little is known about users’ gesture preferences for 3-way displays. We propose a cross-display gesture taxonomy for future explorations of gesture input for multi-display devices, in which we position 3-way displays. Using a requirement elicitation, we report results from two gesture elicitation studies with a total of 48 participants, where a 3-way display was used as a remote control panel for a smart home environment (study #1) and a touchscreen interface for content manipulation performed both within and across displays (study #2). Based on these findings, we offer two consensus datasets of 3-way-display gestures that are consolidated into a larger classification of stroke-gesture input for 3-way displays.
