Tap Zone Actions usability and accessibility

1. Major usability issues of current Tap Zone Actions (TZAs)

1) No visual information on virtual keypad (inherent disadvantage)

2) Assignment of two features on one zone (fig. 1)

• without clue to distinguish meaning of two features

• without clue about how to operate each feature

3) Operation accuracy: gesture

• concern on operating both short tap and long tap accurately

4) Operation efficiency: 3 X 3 grid type of interface for gesture input

• concern on if blind people could select each location easily

2. Major strength of current Tap Zone Actions (TZAs)

1) Intuitive layout mapping interface layout for assigning features to virtual button layout on usage case

2) Comprehensive information display on each zone by putting both labels
