FIELD: physics; computer engineering.
SUBSTANCE: invention relates to user input devices located in portable terminals and portable computers. The device has a display on one side and a keypad on the other, a memory device for storing instructions, and an instruction processor. After receiving information on sensing the first type from the region of the keypad or several separate keys, related to a defined subregion or keys of the keypad region or several keys, and based on instructions stored in memory, the processor visually shows the user through the other side of the device the detected first type of subregion or defined key, and after receiving information on sensing the second type, related to at least sensing effect from the region of the keypad or several keys, related to a defined subregion or key of the region of the keypad or several separate keys, and based on instructions stored in memory, the processor also shows the user through the other side of the device, the detected second type of subregion or key and predetermines action depending on the subregion or key.
