Using the Phone with a Single Input Signal Only: Evaluation of 3dScan's Telephone Module

摘要

SdScan is a scanning-based software system allowing its user to interact with the immediate environment by intentionally contracting a single muscle of choice as input signals. The system is targeted at persons with severe physical impairments with the objective to improve its users' quality of life by empowering them to independently perform certain activities of daily life (ADL), e.g., to open the door by activating a suitable switch or to control the TV remote. The required input signals can, for example, be produced by merely raising the eyebrow ('frowning') and thus demand only a minimum of physical effort. A recent design change in 3dScan's data acquisition component made it possible to add telephony functionality to the list of supported ADL's. The proposed poster describes 3dScan:s telephone module which now is already in a revised and mature state. The usability of the newest version of the module was tested in two evaluations, where the second one involved participants belonging to the target population, and the results are presented in the poster.
