Button design: Size, spacing etc.
- user had difficulty seeing the small labels on the keys and asked to have the keypad held closer
- stated that the symbols on the keys should be more defined
- did not find that the key groupings helped to identify the key functions
- found the square keys more helpful in identifying the functions
- user stated that symbols were not helpful.
- user found the size of the keys to be OK, but thought that they could be a little biggerthought that the distance between the keys could be a bit bigger for both visual identification as well as ease of usevolume, zoom, and screen reader keys easier to push
- Observer hypothesis: the square keys are easier to push than the arrow keys - so by comparison the left side keys are easier.
- Observer hypothesis: Also due to their shape, size, and proximity to the user, they are easier than the smaller triangle keys and the square keys which are further away (thus requiring more force to push with stick).
- Sizes:
- found the size of the keys to be OK, but thought that they could be a little bigger
- user would generally prefer a larger keyboard
- test administrator observation: arrow keys are oddly shaped and hard to press using a stick.
- Spacing:
- thought that the distance between the keys could be a bit bigger for both visual identification as well as ease of use
- Labels & Cues:
- user had difficulty seeing the small labels on the keys and asked to have the keypad held closer
- stated that the symbols on the keys should be more defined
- when asked if he would prefer text labels he said yes
- user would prefer to have an audible/tactile click when the keys are pressed
Visual Identification
- identified the volume down key as a number sign
- thought the volume up key might be a memory key
- thought the home key might be an up arrow
- identified the question mark and stated that he would press this key to get information
- stated that he expected that the triangular navigational keys would "work a cursor"
- stated that the central select key would be used "to click on"
- stated that the zoom key symbol "looks like an eyeglass" and he expected it would be used to enlarge text (and added that this feature would be useful to him)
- when asked what he thought the key on the upper right of the keypad might be for (back/undo key) he stated that he had no idea
...
- through trial and error, user identified the screen reader on/off key as well as the zoom key
- when asked to zoom back out, user tried the screen reader key, volume keys, select key, then the zoom key
- when asked to turn the screen reader back on the user found it again through trial and error
- when asked to turn the volume up, user tried pressing the home key twice (earlier identified as an up arrow), then tried pressing the up cursor keys.
- user then proceeded to tap randomly on keys until the volume was increased
- stated that they did not expect the speaker button to do what it did.
General
- when asked to describe overall experience and comfort level with the keypad, the user gave it a 6/10, where 10 would be very good/comfortable
- user rated comfort with technology a 2 (where 1=very comfortable, 2=comfortable and 3=uncomfortable)
- uses sticky keys, screen reader and mechanical keyboard when on computer at home
