The Gaze TV devices, on show at the IFA electronics trade show, are powered by eye-tracking technology developed by Swedish company Tobii.
During the Berlin event, it was demonstrated how users will be able to call up menus by staring at specific parts of the screen, select icons by gazing directly at them, and alter the volume by looking up and down.
"The free Tobii Gaze Interaction software development kit is available to companies interested in exploring the possibilities of gaze interaction and using this revolutionary technology to develop gaze applications that will take part in the future of computing and consumer electronics," said Tobii chief executive Henrik Eskilsson.
Tobii's eye-tracking technology will eventually be built in to the Gaze TV sets, but the prototype model consisted of an external unit placed in front of the viewer.
The technology was originally developed to help disabled people use computers, and could be harnessed for eye-controlled car information systems, surgery room screens and video games in the future.
