Waggle -- Orientation-based Tablet Interaction
Johannes Schwank, Franca-Alexandra Rupprecht, Achim Ebert · 2017
Nowadays, mobile devices, like smartphones and tablets, are essential items in our daily life. Further, more and more people use tablets in their everyday work for remote control, observing diagrams, performing web analytics, etc. However, the full potential of the tablet usage is not tapped yet; built-in sensors like accelerometer or gyroscope offer a wide range of interaction capabilities, which are not fully used. In this paper, we introduce Waggle -- a novel concept for orientation-based two-handed touch-less interaction on mobile devices through smart tilting and turning. Future design decisions can be founded on two parameters (movement angles and discretization), which are examined in two pilot studies. The first pilot study evaluates the maximum angle for basic rotation axis. The second pilot study tackles the discretization of tilt and turn angles. Both pilot studies are conducted and used to gain the optimal configuration for the two-handed Waggle interaction.
