Many people who are dependent on powerful computer-based communication aids want to keep working with the same software and be able to add modules to the system in line with their requirements. SeeTech has been developed on the basis of longstanding experience to fulfill this wish at low cost. Convenient SeeTech works very precisely and is extremely user-friendly. This eye control system has a large tolerance band, thus there is no need to recalibrate it constantly. Flexible SeeTech is built from modules to meet the user's specific needs and can be expanded without difficulty at any time. The communication software – VS Communicator as standard – always stays the same. Economical SeeTech is truly a low-cost system because it builds on standard components that are available on the market. Only the heart of the system has been specially developed: the software that captures eye movements with a camera, interprets them and passes them to the communication program. SeeTech's modular design permits expansion in line with the user's requirements, which also contributes to making it an economical solution.
