The document summarizes an evaluation of an automated teller machine (ATM) system. It analyzes the tasks users perform with ATMs, the typical user group, and methods used in the evaluation. It identifies critical defects like untrustworthy graphics and confusing navigation. Positives include the regularity of tasks and minimal learning curve. Negatives are misleading titles, too many button options, and lack of location awareness. Overall conclusions are the system is usable but could be improved significantly. Recommendations include better titles, graphics, touchscreens, intuitive actions, and location awareness.

- 15. General Conclusions System is somewhat usable Significant room for improvement Graphics are poor and relate badly Too many choices of physical buttons related to too few on screen choices On screen reading is too much for regular time-on-task Presentation Overview | Task Overview | User Group | Method | Critical Defects | Positives | Negatives | Conclusions | Recommendations 15
- 16. Design Recommendations Label pages with appropriate titles Use graphics or words, not both. If both graphics and words are used, combine as buttons Change to a touch screen, rather than multiple button panels and a screen Clarify actions so that one gesture affords an intuitive action Provide location awareness to users, such as page transitions or a breadcrumb trail Clean up taxonomical issues Combine screens when possible.
