GRASPhere: a prototype to augment indirect touch with grasping gestures

We present in this work GRASPhere, a prototype device that enables users to select and manipulate on-screen objects with grasping gestures. We demonstrate GRASPhere as an extension of a widely-employed force-sensing device, the Phantom OMNI. The hardware design of GRASPhere employs a minimum of components that cost less than $20, which makes our prototype easily replicable for practitioners interested in incorporating grasping gestures into their own force-feedback interactive applications. We discuss application opportunities for GRASPhere, such as exploring multimedia data with physical metaphors and providing assistance to people with visual impairments during indirect touch interaction.
