Everybody in the conversation with your eyes

  1. 1. EVERYBODY IN theconversation by using your eyes to talk
  2. 2. Charlene CullenSpeech PathologistSpeech Language and AAC Consultantcharlenec@spectronics.com.auTwitter: @chacullen
  3. 3. How does it work?• Reflecting invisible infrared light into the eye• Recording the reflection pattern with a sensor system• This is then shown on a computer monitor
  4. 4. A brief history• Last 5 years has seen BIG improvements• No longer need a specific type of tracking for different eyes• Can be used in more environments• Without the need to recalibrate constantly• Can now be used with glasses, contact lenses, head movements, and one eye
  5. 5. Who is it suitable for?• People with significant physical disabilities • Cerebral Palsy • Motor Neurone Disease • Multiple Sclerosis • Quadriplegic• Children and adults with varied medical diagnoses
  6. 6. Types of eye gaze systems• Integrated eye tracking systems that will only work with a specific speech generating device• Stand-alone systems that can be used across a broader range of software and hardware choices.
  7. 7. What can you do?• Communication• Computer access • Email, Word processing, Web browsing• Control of your environment - ECU• Text messaging• Gaming
  8. 8. Video of using eye gaze to play arcade games
  9. 9. DynaVox VMax with Eyemax
  10. 10. InterAACt pagesets• Language Use: interactive focus with quick messages and pre-programmed phrases and sentences for conversation• Language Structure: includes grammatical components for language and literacy learning e.g. keyboards, core word vocabularies and dictionaries
  11. 11. Demonstrate Dynavox Series 5
  12. 12. Tobii C12 with CeyeTobii C15 with Ceye
  13. 13. PCEye
  14. 14. Tobii Communicator 4• Included on the C12 and C15 with Ceye• Add ons • Sono Primo • Sono Key • Sono Lexis • Sono Scribe
  15. 15. Demonstrate TobiiCommunicator 4
  16. 16. Eye gaze assessment• Little clinical research • www.cogain.org• Assessment guidelines • http://www.cogain.org/w/images/5/5a/As sessment.pdf
  17. 17. Eye gaze assessment• Considerations prior to trial: • Physical – head support, explore alternative access, eye tracking selection method, fatigue tolerance • Cognitive – choicemaking, attention, follow instructions, motivation, language level • Visual – move eyes in controlled manner • Environmental – low tech back up
  18. 18. Eye gaze system• How sensitive is it to head movement?• The calibration process• Is it integrated into the device or is it an add on to a standard computer monitor?
  19. 19. Eye gaze system• What communication packages can you use with the device?• Can the device be mounted onto a wheelchair?• How portable is the device?• How is the device charged/battery/plug?
  20. 20. Eye gaze system• Selection Method: • Dwell • Blink • Switch• Does it track one or both eyes?• How well does the system cope with glasses or contacts• Cost
  21. 21. Harry• Single head switch• Row/column scanning• Slow!!!• Tiring!
  22. 22. Harry• Competent in using eye gaze for low tech as an direct access method• Trialled an Eyemax accessory with his own page set• Good for Harry’s positioning
  23. 23. Benefits of direct selection• Less pressure on memory load (Jackson & Wagner, 2006)• Quicker• Increased Control• Eye gaze involves less physical effort (for those with tone fluctuation)
  24. 24. Outcomes “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.”
  25. 25. Outcomes• Easier to talk with his mates in real time• Increased efficiency at completing school work and answering his teachers in class (continue in Mainstream education)• More motivated to use his device
