- Length of Presentation 25 minutes including final quiz
- 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,
- 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.
- The presentation, including video files, can be put on a CD-ROM
and distributed to fellow students.
- 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
- 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
Pros and Cons of Optoelectronics
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.)
Benefits of optoelectronic switches
No need for great force (muscular strength not needed)
Drawbacks to optical switching
No-touch action avoids irritation, hygiene issues
Small sensor geometry allows for placement of sensors and detectors in
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
- Examples of systems using optoelectronic technology,
including evaluations of the efficacy of these systems.
