Abstract

In a wearable electronic device attachable to an arm, a display screen is disposed on a top face of a main body which is attached to the arm. First and second controls are arranged adjacent to opposite sides of the display screen, respectively, and project obliquely from the top face of the main body. The first control is configured to move toward a near side of the display screen by an operation of the user and to return spontaneously to a rest position away from the near side. The second control is configured to move toward a near side of the display screen by an operation of the user and to return spontaneously to a rest position away from the near side. An operation of one of the first and second controls or both of the first and second controls enables setting of the device using the display screen.

Claims

1. An apparatus comprising:

a main body; and

first and second controls that project from a face of the main body, wherein

the first control projects from the face at a first direction of inclination, and the second control projects from the face at a second direction of inclination.

2. The apparatus according to claim 1, wherein the main body is attachable to an arm of a user.

3. The apparatus according to claim 1, further comprising a display screen that is disposed on the face of the main body, wherein the first control is arranged adjacent to a first side of the display screen, and the second control is arranged adjacent to a second side of the display screen which is opposite to the first side.

4. The apparatus according to claim 3, wherein the first control is configured to move toward the first side of the display screen by an operation of the user and to return to a rest position away from the first side,

wherein the second control is configured to move toward the second side of the display screen by an operation of the user and to return to a rest position away from the second side, and

wherein an operation of one of the first and second controls or both of the first and second controls enables setting of the apparatus using the display screen.

5. The apparatus according to claim 4, wherein the display screen displays a list of items to be selected for the setting, the first control is operated to shift a focus on the items in one direction of the list for selection, and the second control is operated to shift a focus on the items in another direction of the list for selection.

6. The apparatus according to claim 4, wherein the first and second controls are operated separately from each other to input the setting, and the first and second controls are operated simultaneously with each other to effectuate the inputted setting in the main body.

7. The apparatus according to claim 4, further comprising a tone generator for generating tones of a music piece, wherein the first and second controls are operated to select and set the music piece in the tone generator.

8. The apparatus according to claim 4, further comprising a third control disposed on the face of the main body in the vicinity of one of the first and second controls in opposed relation to one of the first and second sides of the display screen relative to the one of the first and second controls.

9. The apparatus according to claim 8, wherein the third control is mounted on the face of the main body in the form of a push button.

10. The apparatus according to claim 8, further comprising a support pad disposed in the vicinity of the one of the first and second controls in opposed relation to the one of the first and second sides of the display screen relative to the one of the first and second controls, the support pad being arranged on the face of the main body for supporting a finger which operates the one of the first and second controls.

11. The apparatus according to claim 10, wherein the third control and the support pad are arranged adjacently with each other at the same height from the face of the main body.

12. The apparatus according to claim 8, wherein the one of the first and second controls is operable by a thumb of the user, and the third control is also operable by the thumb of the user.

13. The apparatus according to claim 4, wherein the first and second controls are spaced apart from each other at a span in the order of 20 mm through 50 mm such that the first and second controls are operable concurrently with a thumb and an index finger of the user.

14. The apparatus according to claim 13, wherein the display screen displays a cursor for use in the setting of the apparatus, such that the cursor moves on the display screen in association with the operation of the first and second controls by the thumb and index finger of the user.
