We present GaussBits, which is a system
of the passive magnetic tangible designs that enables 3D tangible
interactions in the near-surface space of portable displays. When a thin
magnetic sensor grid is attached to the back of the display, the 3D
position and partial 3D orientation of the GaussBits can be resolved by
the proposed bi-polar magnetic field tracking technique. This portable
platform can therefore enrich tangible interactions by extending the
design space to the near-surface space. Since non-ferrous materials,
such as the user's hand, do not occlude the magnetic field, interaction
designers can freely incorporate a magnetic unit into an appropriately
shaped non-ferrous object to exploit the metaphors of the real-world
tasks, and users can freely manipulate the GaussBits by hands or using
other non-ferrous tools without causing interference. The presented
example applications and the collected feedback from an explorative
workshop revealed that this new approach is widely applicable.
