Applications of Optoelectronic Technology in AAC
Eleanor M. Kratz
March 13, 2003

  1. Length of Presentation 25 minutes including final quiz
  2. There will be a quiz of 5 questions given out at the beginning of the presentation, with the answers given at the end. The quiz will be on a handout, with the answers written somewhere (upside down, other side, etc....)
  3. Presentation should be rich in audiovisual content: e.g., video, slides, handouts. The materials can be presented in PowerPoint format with video and audio and animations, etc.
  4. The presentation, including video files, can be put on a CD-ROM and distributed to fellow students.
  5. While you are preparing your presentation, you are encouraged to place materials, including this Prolegomena, on the web, through our web site. This is an important part of our course, since it fosters team participation.
  6. Rehearse and time your presentation. JBE will be forced to use the "HOOK" if you go over even by 1 nanosecond!
Introduction to Optoelectronics
Some definitions and examples
Emitters of Visible and Invisible Light (ultraviolet and infrared)
Sensors of Light (phototransistors, sensor arrays, cameras, etc.)
Remote Signaling (remote control devices, wireless interaction, etc.)
Pros and Cons of Optoelectronics
Benefits of optoelectronic switches
No need for great force (muscular strength not needed)
No-touch action avoids irritation, hygiene issues
Small sensor geometry allows for placement of sensors and detectors in close quarters.
Drawbacks to optical switching
Expense (in certain cases)
Required expertise (in certain cases)
Lack of proprioceptive and kinesthetic tactile feedback, may be compensated by visual and auditory feedback.

Characteristics of potential users of optoelectronic technology.

Review of the literature
  1. Examples of systems using optoelectronic technology, including evaluations of the efficacy of these systems.
  2. Journal articles
  3. Catalogs and advertisements of companies
  4. Internet
  5. Video clips

Case Study
How optoelectronics is being used with a nonspeaking, motorically limted six-year-old boy.
