    3. 3. How does it work?<br />Reflecting invisible infrared light into the eye<br />Recording the reflection pattern with a sensor system<br />This is then shown on a computer monitor<br />
    4. 4. A brief history<br />Last 5 years has seen BIG improvements<br />No longer need a specific type of tracking for different eyes<br />Can be used in more environments<br />Without the need to recalibrate constantly<br />Can now be used with glasses, contact lenses, head movements, and one eye<br />
    5. 5. Who is it suitable for?<br />People with significant physical disabilities<br />Cerebral Palsy<br />Motor Neurone Disease<br />Multiple Sclerosis <br />Quadriplegic <br />Children and adults with varied medical diagnoses<br />
    6. 6. DynaVox VMax with Eyemax<br />
    7. 7.
    8. 8. Language Use<br />Relies on conversational messages that are designed to encourage interaction<br />It focuses on interaction, conversation, quick messages and messages that are based on pre-programmed phrases and sentences<br />Allows the ability to maintain and manage the flow of a conversation<br />
    9. 9. Language Structure<br />Building blocks for developing higher level language skills <br />Includes grammatical components for language and literacy learning<br />Can compose novel messages for either spoken or written communication<br />Keyboards, core word vocabularies and dictionaries<br />
    10. 10.
    11. 11. Connections to our world<br />Email - free DynaVox account with every device plus a variety of pre-programmed email pages<br />Computer access –integrated or with Access IT<br />Control of your environment - ECU<br />Text messaging via Bluetooth<br />

    19. 19. Eyegaze assessment<br />Little clinical research<br />www.cogain.org<br />Considerations prior to assessment:<br />Seating and positioning<br />Medication side effects eg. Blurred vision<br />Current vision status<br />Personal characteristics of motivation and patience (Lund & Light 07)<br />
    20. 20. Eyegaze assessment<br />Individual abilities:<br />Physical<br />Cognitive status<br />Language level<br />Vision<br />Current seating and positioning<br />
    21. 21. Eyegaze assessment<br />Individual abilities:<br />Head movement and range<br />Presence of whole body movements<br />Other access options eg. Switch, scan<br />Endurance<br />Pain<br />Disease Progression<br />
    22. 22. Eyegaze system<br />How sensitive is it to head movement?<br />The calibration process<br />Is it integrated into the device or is it an add on to a standard computer monitor?<br />
    23. 23. Eyegaze system<br />What communication packages can you use with the device?<br />Can the device be mounted onto a wheelchair?<br />How portable is the device?<br />How is the device charged/battery/plug?<br />
    24. 24. Eyegaze system<br />Selection Method:<br />Dwell<br />Blink<br />Switch<br />Does it track one or both eyes?<br />How well does the system cope with glasses or contacts<br />Cost<br />Najafi, Friday & Robertson, 2008<br />
    25. 25. Harry<br /> Single head switch<br /> Row/column scanning<br /> Slow!!!<br /> Tiring!<br />
    26. 26. Harry<br />Competent in using eyegaze for low tech as an direct access method<br />Trialled an Eyemax accessory with his own page set<br />Good for Harry’s positioning<br />
    27. 27. Less pressure on memory load (Jackson & Wagner, 2006)<br />Quicker<br />Increased Control<br />Eye-gaze involves less physical effort (for those with tone fluctuation)<br />Benefits of direct selection<br />
    28. 28. Outcomes<br />“At his cousin’s birthday on the weekend I looked over and saw him chatting and laughing away. I walked across and heard that he was really involved in conversation with the group about an AFL footballer – and he had started the conversation! People were amazed as it’s the first time we have seen Harry initiate a conversation.”<br />
    29. 29. Easier to talk with his mates in real time<br />Increased efficiency at completing school work and answering his teachers in class (continue in Mainstream education)<br />More motivated to use his device<br />Outcomes<br />
