Abstract

An electronic apparatus 20 is of a portable type and has a thin body integral with a display screen holdable by both hands HR, HL of a user for viewing purposes. Disposed on a front of the body 21 are a flat display panel 22 and various operation buttons 23–27, and first and second touch sensors 28 and 29. The first touch sensor 28 is disposed on the apparatus at a position where when the body 21 is held by both the hands of the user, a touch surface of the first sensor 28 is easily operated vertically by a finger of the user's right-hand HR whereas the second touch sensor 29 is disposed at a position where when the body 21 is held by both the hands of the user, its touch surface is easily operated horizontally by a finger of the user's left-hand HL.

Claims14

Dependent claims

A portable electronic apparatus comprising:

a display device;
a first touch sensor which extends vertically on a side of the display device, and a second touch sensor which extends horizontally on a side of the display device, each of the first and second touch sensors being adapted to sense a plurality of touch patterns;
a memory which stores a plurality of data items;
a selection section for selecting a mode of the apparatus as one of a selection mode for selecting one of the data items from the memory and a display/edit mode for at least one of displaying and editing the selected data item;
an action controlling information memory which stores:
(a) selection mode action controlling information which indicates an action to be taken when each of the plurality of touch patterns is input while the selection mode is selected, and (b) display/edit mode action controlling information which indicates an action to be taken when each of the plurality of touch patterns is input while the display/edit mode is selected;
and
a display control section which, when one of the touch patterns is sensed by at least one of the first touch sensor and the second touch sensor, reads out the action controlling information corresponding to the sensed touch pattern and the selected mode, and controls the display device in accordance with the read action controlling information.
