Finding
Yes. Touch precision, menu depth, voice recognition, device position, competing devices and the conditions of use can make a technically capable interface functionally unavailable.
How the mechanism works
The interface imposes demands on recognition, reach, timing, memory, speech, movement and attention. When a required demand is not reliably available, the pathway stops.
Evidence boundary
The same interface may be available to one operator and unavailable to another, or vary by location and time.
