Operation Analysis of Two Devices

         
       

Set the alarm clock for 8:30 am.

Dream Machine FM/AM Clock Radio ICF-C212:


MULTI-PRESS

t↓ h↓ x/1 + 59 t↑ =72 operations/10 sec

PRESS+HOLD

t↓ h↓ m↓ t↑ =4 operations/30 sec

30 sec

Blackberry Pearl:

 

t↓ h↓ m↓ t↑ = 0.333 operations/12 sec
??? ??????
12 sec

I believe this interface is a lot easier to navigate using the rollover pearl. Scrolling up and down is fast. Although this interface offers many extra options like "Snooze," "Active on Weekends,""Alert Type," "Tune," "Volume," and "Number of Beeps" (6 additional operations), they are secondary to the primary operations "Daily Alarm" and "Time." The "set" and "click" buttons make the interface easier to navigate through than the number pads. The only downside is that the user must scroll up to change the hours and minutes. This gesture feels awkward.
