Provide at least one mode that is operable with userlimited reach and strength.
1. Some individuals may have difficulty operating systems which require reach or strength. The most straight-forward solution to this problem is to place the controls where they can be easily reached with minimal changes to body position. Many products also have controls located on different parts of the product.
2. When this is the case, the following strategies may be used:
a.Allow the functions to be controlled from the keyboard, which is located directly in front of the user.
b. Allow voice recognition to be used as an option. This provides input flexibility, but should never be the only means for achieving a function.
c. Provide a remote control option that moves all of the controls for the product together on a unit that can be positioned optimally for the individual. This allows the individual to operate the product without having to move to it. If this strategy is used, a standard communication format would be important to allow the use of alternate remote controls for those who cannot use the standard remote control.
d. Reduce the force needed to operate controls or latches and avoid the need for sustained pressure or activity (e.g., use guards rather than increased strength requirements to avoid accidental activation of crucial switches).
e. Provide arm or wrist rests or supports, create short cuts that reduce the number of actions needed, or completely eliminate the need to operate controls wherever possible by having automatic adjustments.
f. Section 4.34.3 of the Americans with Disabilities Act Accessibility Guidelines (ADAAG) also contains specific information concerning reach ranges. ADAAG gives specific guidance concerning access to the built environment. Section 4.34.3 indicates the reach ranges for a front or parallel approach to equipment for individuals using a wheelchair. This information may provide useful for those telecommunications manufacturers whose equipment is stationary, such as an information kiosk.
