| ERICA's hardware and software system grants people with disabilities a means to easily control off-the-shelf Windows™ applications with their eye. ERT's patented eye-tracking system, the Eye-gaze Response Interface Computer Aid (ERICA), is a unique device that determines where its user is looking on a computer display. ACCURATE, RELIABLE, & NONINVAISIVE -- Hardware -- The system is completely noninvasive; the device requires no attachments to be worn by the user. The system uses a camera and infrared light to create effects off the user's eye. These effects are used to compute where someone is looking. The camera and light source are compact units that can be used with any Windows’ based desktop or laptop or tablet PC system. It can also be mounted on a wheelchair. Furthermore, ERICA can accurately calculate the gaze position for people wearing glasses and contacts. The system can identify where someone is looking 60 times a second and has an accuracy rating of 0.5 degrees visual angle. This translates to approximately 0.5 to 1 centimeter accuracy on a computer monitor when sitting at a normal viewing distance. ERICA's imaging system is fully integrated into the Windows™ 95, 98, ME, NT, 2000, or XP platforms. ERICA is also available for (Apple) Macintosh computers. -- Software -- ERICA's GazeTracker™ software allows researchers to capture and then analyze a person's eye-gaze response to still images, videos, or computer software. GazeTracker™'s strength rests in the powerful analytical and visualization tools it provides and the enormous flexibility with which it allows researchers to define their tests. ERICA's Computer Control software allows individuals with disabilities to seamlessly operate any software running on a Windows™ computer. ERICA's proven techniques allow efficient software access. |
