Patent ID: 8289817

Claim:
A touch key operated alarm clock in which all time entries can be entered and set with a succession of touches with a single finger, which gives visual assurance of keystrokes, to thereby ensure accurate entry of data, as well as alarm activation, and in which the setting of all times consists of using three separated singularly functional key groups for time entry in three progressive steps, comprises: a) a front facing display screen having a time display portion to display time-of-day and alarm time; b) a lateral keypad consisting of three separated, singularly functional groups of keys for time entry; each group configured and located for the progressive entry of data, which consists of an entry in each of the groups of keys: i) a first functional group of keys which provides only a choice of clock time-set function keys; ii) a second functional group of keys, which provides only a ten numeric key group numbered 0-9 for entering numbers; and, iii) a third functional group of keys which provides only a choice of AM-PM/Set function keys, to finalize any time setting sequence; so that all time entries can be entered and set by touch alone with a single finger, using a maximum of six touches, thereby providing visual feedback and assurance of not only accurate but complete entry, without any need to hold or grasp the clock, and without any need for a user to reorient himself from a position facing the clock, or to reorient the clock from its operable, optimally viewed orientation; and, so that after a user has set an alarm time, consisting of an entry in each of the three functional groups of keys, he then can at any time review all his entries.
