Usability Guidelines for Self-Service Touch-Screen Kiosks

The self-service, touch-screen kiosk must be easy and simple to use by people who have little computer experience, a low literacy level, and no prior experience with the kiosk application. In addition, touch-screen users expect to spend a short time at the kiosk since they are typically standing and can only use their fingers to perform actions. This means that the kiosk application must allow users to complete a task in just a few, uncomplicated steps.
