A new form of input arrangement for cursor control devices or other handheld electronic devices in which the activation surfaces are designed to allow the fingers and thumb of the user to effect commands by means of non-repetitive motion as compared to current devices. Specifically, sensors are associated with the fingers and thumb which sense motion in not only the downward direction, as generally used in current devices, but also in forward backward and side directions to carry out a command. The resulting ability of the user to vary the points of pressure and other stresses onto different surfaces of the digits and corresponding nerves and muscles serves to relieve discomfort and pain resulting from current devices. A keyboard on the rear wall of a handheld electronic alleviates the overuse and damage to the thumbs and associated nerves and muscles attendant to current methods and apparatus for data entry. The arrangement includes extension of the keyboard to the back of the device so that both the thumbs and fingers may be utilized in entering data. This arrangement may incorporate the same type of individual key input for each finger as was disclosed above for use in the cursor control. The essence of such an arrangement includes the provision of positioning input sensors or switches in such a way relative to each finger and thumb that several keys may be activated by movement of the finger in various directions, more specifically as shown and described. This may allow different motions to produce a common input or command to thereby distribute the stress attendant to executing an input / command over different digits or the same digit in a different way. Alternatively, by permitting small but differently directed motions to be detected from a singe digit, the arrangement permits an enhanced efficiency for entering commands and data in a hand held electronic device.
