A Naïve and Fast Human Computer Interface Controllable for the Inexperienced - a Performance Study

We present a human computer interface (HCI) which can be prepared in less than five minutes and reaches a high accuracy with naive users. With additional learning the success rate increases drastically. Using the EOG for control of a cursor we show how the interface between man and machine can be established quickly. Off the shelf hardware components were used for the setup, including an already approved amplifier for human use. The graphical user interface with optical and acoustical feedback consisted of self developed software. With the proposed interface we reached a maximum bit rate of 57.7 bit/min with untrained users.
