Ho trovato queste 10 regole da seguire per la realizzazione di un buon sistema basato su touch screen. Sono abbastanza ovvie, ma è meglio comunque pensare a questi aspetti in fase di analisi e progettazione!
Kiosk Design Guidelines
Chauncey Wilson
1. There are no expert users. Users might gain some knowledge with repeat visits, but the visits are far apart so retention is minimal.
2. Make all buttons large (people may be carrying purses, briefcases, or children) and label the buttons clearly.
3. While the kiosk may not be international, there may be users who speak little English so language variants may be needed. Make it easy to switch languages.
4. Do not use standard controls like scroll bars and close boxes. For non-computer users, these controls are not intuitive.
5. Provide simple, but clear instructions for navigation and provide tips on what to click (since some users may never have used a computer).
6. Review ATM literature for tips on designing for a wide range of busy users.
7. Provide adequate time-outs for general information and shorter time outs for private information. For example, if the purpose of your kiosk is to get medical information from a patient before an exam, you should build in a short time-out for the screen so the information isn’t there if the patient is suddenly asked to go to an exam room.
8. If a person has to fill in personal information (medical or financial, for example), consider designing the kiosk so that each user has some privacy.
9. Make navigation linear and provide very clear exits.
10. Provide clear feedback about the actions the users take and make sure that titles clearly provide context. Provide a way to start over easily.
