Fusion4D: 4D Unencumbered Direct Manipulation and Visualization

It is possible to predict that sometime in the future, holographic interactive displays will be available as household commodities, requiring new interaction techniques. Fusion4D is our proposal for unencumbered direct manipulation interfaces involving three dimensions in physical space, as well as a fourth data-dependent dimension (such as time-varying information of an object.) A proof-of-concept prototype has been developed and subjected to user testing. The results of the tests indicate that there are some points for improvement, such as the visualization technology, but the system is well accepted by users.
