Abstract

Provided is a data-processing device which includes a flexible position-input portion capable of sensing proximity or touch of an object such as a user'"'"'s palm and fingers. The data-processing device is arranged so that, in accordance with the position of the user'"'"'s palm and fingers holding the data-processing device, an image for operation is displayed in a location which is accessible by the fingers.

Claims

1. A driving method of a portable data-processing device, the driving method comprising:

sensing touch of a palm of a hand of a user by a first region located at a first side surface of the portable data-processing device when the portable data-processing device is held by the hand;

sensing touch of a finger of the hand other than a thumb by a second region located at a second side surface of the portable data-processing device when the portable data-processing device is held by the hand; and

displaying an image used for operating the portable data-processing device on a third region comprising a display portion so that the image is located in a movable range of the thumb of the user holding the portable data-processing device,

wherein the second side surface faces the first side surface with the display portion interposed therebetween.

2. The driving method according to claim 1,

wherein the first region and the second region are configured to display an image.

3. The driving method according to claim 1,

wherein the first region, the second region, and the third region each comprise a touch sensor.

4. The driving method according to claim 1,

wherein the third region is in contact with the first region and the second region.

5. A portable data-processing device comprising:

a display portion including continuous first to third regions each comprising a touch sensor, the third region being interposed between the first region and the second region,

wherein the first region faces the second region,

wherein the touch sensor in the first region is configured to sense touch of a palm of a hand of a user when the portable data-processing device is held by the hand,

wherein the touch sensor in the second region is configured to sense touch of a finger of the hand other than a thumb when the portable data-processing device is held by the hand, and

wherein the third region is configured to display an image used for operating the portable data-processing device so that the image is located in a movable range of the thumb of the user holding the portable data-processing device.

6. The portable data-processing device according to claim 5,

wherein the display portion is flexible.

7. The portable data-processing device according to claim 5,

wherein the touch sensor is flexible.

8. The portable data-processing device according to claim 5,

wherein the touch sensor is a capacitive touch sensor.

9. A portable data-processing device comprising:

a display portion comprising continuous first to third regions, the third region being interposed between the first region and the second region,

wherein the first region faces the second region,

wherein the first to third regions each comprise a pixel and an imaging pixel,

wherein each of the pixels in the first to third regions comprises an element including a display media,

wherein each of the imaging pixels in the first to third regions comprises a photoelectric conversion element,

wherein the imaging pixel in the first region is configured to sense touch of a palm of a hand of a user when the portable data-processing device is held by the hand,

wherein the imaging pixel in the second region is configured to sense touch of a finger of the hand other than a thumb when the portable data-processing device is held by the hand, and

wherein the third region is configured to display an image used for operating the portable data-processing device so that the image is located in a movable range of the thumb of the user holding the portable data-processing device.

10. The portable data-processing device according to claim 9,

wherein the display portion is flexible.
