Patent ID: 8498181

Claim:
An alarm clock application for a device having a touch screen, wherein time entry consists of progressively entering data into each of three singularly functional groups of keys for time entry, comprises: a) a time display portion having a four digit time display; and, b) a keypad portion 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 three groups of keys: i) a first functional group of keys which provides only a choice between a clock time set function key and an alarm time set function key; ii) a second functional group of keys, which provides a ten numeric key group numbered 0-9 for entering numbers; and, iii) a third group of keys which provides only a choice of AM-PM function keys, to finalize any time setting sequence; wherein time entry consists of progressively entering data into each of the three singularly functional groups of keys; so that the clock can be fully operated 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 data entry; 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.
