This storyboard design revolves around a very simple and visual navigation box, which is a stretch metaphor for a telephone key pad. The division of nine squares to different tasks is a more natural partition for seniors rather than nine menu items. In addition, the visual icons and pictures send a clear signal of the relevant task at hand.
When a user selects to ask a question, the navigation pad zooms to the top left corner and the rest of the screen real estate is freed up to display questions he could answer. Similarly, a user can select to join a live chat, for which the navigation zooms out and the user is brought to a simple video chat interface where he could contribute to the live chat and see a list of participating members. The user could click on any user to view his profile and add them as a contact.
Analysis:
Learnability:
Efficiency:
- The 9 tiles layout is analogous to the phone pad. The users will know each tile corresponds to one functionality
- The home button at the upper left hand corner is externally consistent with other apps
Efficiency:
- Having each of the tiles, except the middle one, extend to the boarder, the hit zone for each icon becomes infinitely big. Users can hit the functionality he/she wants much quicker with less chance of error
- The menu is flat. All the functions are one click away, and the home menu is also one click away, making navigation very straightforward and efficient
Safety:
- Large icons, visual cues and buttons is safer in terms of less accidental mis-clicks
- Most actions do not have a natural undo option, which decreases efficiency, but also means elders have two steps to go back (home + choose again)
- Selecting home may cause progress loss in terms of accidentally clicking on home, say if elder was typing an answer
