3DScan: an environment control system supporting persons with severe motor impairments

This proposal is about a poster dealing with a scanningbased software system, which aims at giving persons with severe motor impairments a means to interact with their immediate environment by issuing tiny contractions of an arbitrary muscle. The implementation makes use of an extension of row-column scanning, called three-dimensional scanning, which reduces the time required to select a certain item by eliminating the need to scan long rows or columns. A simple experiment comparing the resulting text entry capabilities to conventional row-column scanning shows that the entry rate can be increased by over 30 %.
