Q4. What if a user wants basic communication only and does not have a computer?

Q5. How many models of VisionKey are there and what are the differences between them?
A. There are 3 models: (VisionKey 5+, 6 are available for the left or right eye)

1. VisionKey 5.3 (5.3V, 5.3H) is our standard model (pictured below) and is for users with regular eye control with an option for impaired eye control included; that is users can move their eyes in horizontal, vertical and diagonal directions or in one direction only. This allows for progressive eye control deterioration (e.g. ALS). VisionKey 5+ uses direct selection or scanning.


2. VisionKey 6.3 (6.3V, 6.3H) is our scanning model and is for users who have definitive impaired eye movements and can move their eyes in one direction only (e.g. Locked-in-syndrome). We now have 2 versions of this model where users can either look up or down (6V) or left or right (6H) to make selections. VisionKey 6 uses sequential scan selection.

3. VisionKey 7.3 (pictured below) is our evaluation model and is for rehabilitation professionals and distribution partners to assess the applicability of VisionKey for a particular user. VisionKey 7 has adjustable features for assessment purposes.

Q6. When using VisionKey with a computer, does the user have to be sitting in front of the computer?
A. No. As the VisionKey Viewer is mounted on a pair of standard glasses, a user can be sitting, reclining or even lying in bed when using VisionKey. (And remember, VisionKey works in all of these positions without a computer too!)

Q7. How long can a user keep VisionKey on?
A. This is very individual; we have some users who use the system for 10-11 hours at a time. During the training period, we recommend that users gradually increase the time of use as some users experience initial sensitivity to pressure on the nose and/or eye fatigue (see Q8).

Q8. Does VisionKey cause fatigue or dizziness?
A. Some users experience eye fatigue initially (1- 3 times of wearing VisionKey), but this soon disappears as the eyes and the brain become accustomed to the eye movements required. Users wear the unit up to 10 hours a day with no problems. No users have reported any headaches or feelings of dizziness.

Q12. Does VisionKey have voice output?

Q14. How long does it take to learn VisionKey?
A. VisionKey has graduated learning of 3 charts for user ease and operational control (Word-chart, Basic ABC-chart and Advanced ABC-chart). The Word-chart is typically learned within minutes.
