Grasp Interaction with Tablets

Drawing on empirical research, this book sets out design guidance for a prospective tablet that supports comfortable interaction on both its front and its rear surface. Its aim is to help interface designers and app developers create ergonomic software for such devices, especially those that take input from the back. Manufacturers, the author suggests, can also find support here for treating rear-side interaction as a useful addition to the interaction design space, one that expands input options and opens new design possibilities while performing well for users.

The guidelines are built around how people actually hold a tablet, with the aim of matching the skills users already have to this new form factor. Three areas receive particular attention: ergonomic gestures, the zones of the device that are suited to interaction, and pointing techniques. Together they form the foundation for the recommendations.
