Subject: [teitac-hardware] Summary of touch based controls from
This is an attempt to summarize key points from a transcript.
Unfortunately, there are sections that were not very clear.
Mechanical and touch sensitive controls need to be separated. In fact
there may be 3 types of controls to consider:
2. Touch sensitive
3. Touch dependent (biometric)
Mechanical controls may not be the best alternative to a touch sensitive
control - language should be drafted to allow alternatives
Touch screen versus touch sensitive:
* touch screen more of a biometric technology
* touch sensitive is still a "mechanically" driven solution but
there is greater control of the sensitivity and timing characteristics.
The example give was adaptive controls on a microwave
Potential touch sensitive characteristics:
* Control must be tactilely discernible
* Control must have a mechanism to minimize accidental activation
due to touch
* Control characteristics, such as time to registration of signal,
pressure, etc., should be adjustable
Potential touch screen content:
* An alternative method to achieve touch screen control functions
must be provided via an alternative format or interact (for example
