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.

7. Functional Positives
Well... the system seems to work
Regularity of task performed
Minimal learning curve with system
Regardless of errors, if enough buttons are pushed,
a positive result will be reached.

9. Functional Negatives
Page titles are misleading
Graphics are confusing
Too many haptic choices
Directions don’t afford easiest solution
No breadcrumb trails
Lack of user awareness of location
Confusing taxonomy, i.e. “transaction”

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

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.
