Abstract

According to one embodiment, a portable device includes a casing, a display contained in the casing and having a first side in proximity to a position of the casing which is held by a user with a hand, a plurality of icons displayed on the display, a touch panel which is provided over the display and by which the icons are operated, and a sensor which is provided in the casing and senses the position held by the user. The icons are arranged in a first area defined by an arc of a circle about a first corner as a center located at a lower end of the first side, and chords extending between the arc and the first corner.

Claims

1. A portable device comprising:

a casing;

a display in the casing comprising a first side;

a plurality of icons displayed on the display;

a touch panel above the display and by which the icons are operated; and

a touch-sensitive sensor in the casing configured to sense a depression on the casing,

wherein the icons are positioned in a first area defined by an arc and two sides of the display located at a lower end of a first corner of the display.

2. The portable device of claim 1, wherein the first area is corresponding to a reach of a thumb of a hand holding the casing.

3. The portable device of claim 2, wherein the first area is scaled up and down in accordance with a length of the thumb of the hand.

4. The portable device of claim 3, wherein the first area is one area which corresponds to the thumb of the hand.

5. The portable device of claim 4, wherein the icons are moved from the first area to a second area defined by an arc and two sides of the display located at a lower end of a second corner of the display corresponding to a sensed trajectory on the touch panel.

6. The portable device of claim 5, wherein the casing comprises a first surface on which the display is arranged and a second surface opposite to the first surface, the second surface comprising a finger hold portion to hold a finger.

7. The portable device of claim 6, wherein the second surface comprises an attachment portion to which a strap is attached, and the hand is passed through the strap.

8. The portable device of claim 4, further comprising:

a removable pen input device attached to the casing configured to operate the icons via the touch panel; and

a detecting portion in the casing configured to detect that the pen input device has been removed from the casing,

wherein the icons are moved to a second area defined by an arc and two sides of the display located at a second corner of the display, when the detecting portion detects removal of the pen input device.

9. The portable device of claim 8, wherein the casing comprises a first surface on which the display is arranged and a second surface opposite to the first surface, the second surface comprising a finger hold portion to hold a finger.

10. The portable device of claim 9, wherein the second surface comprises an attachment portion to which a strap is attached, and the hand is passed through the strap.

11. The portable device of claim 3, wherein:

the first area comprises a first portion corresponding to a first hand and a second portion corresponding to a second hand; and

the first portion and the second portion comprise a same set of the icons.

12. The portable device of claim 3, wherein:

the first area comprises a first portion and a second portion; and

the first portion comprises a first set of the icons and the second portion comprises a second set of the icons different from the first set of icons.
