Abstract

Portable electronic apparatus includes a display unit (ELD); a first sensor element group (G1) having a plurality of sensor elements (L1-L4) for detecting a contact and arranged continuously around the display unit side by side; a switch element formed where the first sensor element group is arranged; and a control unit for controlling the portable electronic apparatus to display a plurality of selection candidate items which can be displayed as an operation target region on the display unit, to monitor a change in a detection state of the first sensor element group and a state of the switch element, to change a selection state of a selection candidate item by changing the selection candidate items and/or the operation target region based on the change in the detection state of the first sensor element group, and to execute a selection candidate item in the selection state when the switch element is pressed.

Claims

1. Portable electronic apparatus comprising:

a display unit;

a first sensor element group having a plurality of sensor elements for detecting a contact and arranged continuously adjacent to the display unit side by side;

a switch element formed where the first sensor element group is arranged, wherein the switch element is arranged to overlap a first sensor element and a second sensor element of the plurality of sensor elements; and

a control unit for monitoring a change in a detection state of the first sensor element group and a state of the switch element,

wherein, when respectively different processing is assigned to a press of the switch element and a contact of the first sensor element and the second sensor element, the control unit regards a contact detection of the first sensor element and the second sensor element as invalid in a case that the first sensor element and the second sensor element detects the contact when the press of the switch element is detected.

2. The portable electronic apparatus according to claim 1, wherein

a direction component of an arrangement of the plurality of sensor elements composing the first sensor element group comprises at least a first direction, and

the control unit controls the display unit to display the plurality of selection candidate items in a parallel direction to the first direction, and to change the selection candidate items and/or the operation target region along the first direction according to a change in a detection state of the first sensor element group.

3. The portable electronic apparatus according to claim 1, wherein the switch element is formed around a central portion of a line connecting centers of the plurality of sensor elements.

4. The portable electronic apparatus according to claim 1, wherein the control unit regards a press of the switch element as valid when one of the selection candidate items is displayed as the operation target region, otherwise it regards the press of the switch element as invalid.

5. The portable electronic apparatus according to claim 1, further comprising a second sensor element group having a plurality of sensor elements arranged symmetrically to the first sensor element group, wherein the display unit is placed between them.

6. The portable electronic apparatus according to claim 1, wherein the control unit allows the display unit to display a plurality of selection candidate items that can be displayed as an operation target region on the display unit, changes a selection state of a selection candidate item by changing the selection candidate items and/or the operation target region based on the change in the detection state of the first sensor element group, and executes a selection candidate item in the selection state when the switch element is pressed.

7. A control method of a portable electronic apparatus comprising a display unit, a first sensor element group having a plurality of sensor elements for detecting a contact and arranged continuously adjacent to the display unit side by side, and a switch element formed where the first sensor element group is arranged, wherein the switch element is arranged to overlap a first sensor element and a second sensor element of the plurality of sensor elements, comprising:

monitoring a change in a detection state of the first sensor element group and a state of the switch element; and

regarding a contact detection of the first sensor element and the second sensor element as invalid, when respectively different processing is assigned to a press of the switch element and a contact of the first sensor element and the second sensor element, in a case that the first sensor element and the second sensor element detects the contact when the press of the switch element is detected.
