7Presentation Overview | Task Overview | User Group | Method | Critical Defects | Positives | Negatives | Conclusions | Recommendations
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.
but maybe I’m just being nice.
9Presentation Overview | Task Overview | User Group | Method | Critical Defects | Positives | Negatives | Conclusions | Recommendations
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”

15Presentation Overview | Task Overview | User Group | Method | Critical Defects | Positives | Negatives | Conclusions | Recommendations
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
16Presentation Overview | Task Overview | User Group | Method | Critical Defects | Positives | Negatives | Conclusions | Recommendations
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.
