Abstract

A control panel device for providing human-machine interface with aid of optical detection and associated method are provided. The control panel device may include a magnetic component that is positioned below a first surface of the control panel device, a moveable component that is positioned above the first surface, and an optical tracking sensor (OTS) that is positioned below the first surface. The moveable component is magnetically attracted by the magnetic component to attach to the first surface. In addition, the OTS may be arranged to sense movement or rotation of the moveable component as at least one user input in order to generate at least one output corresponding to the at least one user input.

First claim

What is claimed is:

1 . A control panel device, for providing human-machine interface with aid of optical detection, the control panel device comprising:
a magnetic component, positioned below a first surface of the control panel device; a moveable component, positioned above the first surface, wherein the moveable component is magnetically attracted by the magnetic component to attach to the first surface; and an optical tracking sensor (OTS), positioned below the first surface, arranged to sense movement or rotation of the moveable component as at least one user input in order to generate at least one output corresponding to the at least one user input.

2 . The control panel device of claim 1 , wherein the magnetic component comprises at least one first magnet.

3 . The control panel device of claim 2 , wherein the at least one first magnet comprises multiple first magnets, wherein the multiple first magnets are arranged according to a first predetermined magnet arrangement pattern.

4 . The control panel device of claim 3 , wherein the moveable component comprises multiple second magnets, wherein the multiple second magnets are arranged according to a second predetermined magnet arrangement pattern corresponding to the first predetermined magnet arrangement pattern, for aligning the moveable component to a first predetermined direction on the first surface when the moveable component is magnetically attracted by the magnetic component.

5 . The control panel device of claim 2 , wherein the at least one first magnet comprises a single first magnet.

6 . The control panel device of claim 1 , wherein at least one portion of the moveable component is moveable with respect to the first surface, for receiving the at least one user input for the control panel device.

7 . The control panel device of claim 1 , further comprising:
at least one locking component, for locking the moveable component onto the first surface; wherein the moveable component comprises at least one first extending structure corresponding to the at least one locking component, for being inserted between at least one second extending structure of the at least one locking component and the first surface.

8 . The control panel device of claim 1 , wherein the moveable component comprises:
a base, magnetically attracted by the magnetic component to attach to the first surface; and a moveable sub-component, supported by the base, moveable with respect to the first surface, for receiving the at least one user input for the control panel device.

9 . The control panel device of claim 8 , wherein the base comprises one or a combination of at least one ferromagnetic material and a set of magnets.

10 . The control panel device of claim 8 , wherein the moveable sub-component is moveable with respect to at least one axis.

11 . The control panel device of claim 10 , wherein the moveable sub-component is rotatable with respect to a first axis among the at least one axis.

12 . The control panel device of claim 11 , wherein the moveable sub-component is pressable along the first axis.

13 . The control panel device of claim 11 , wherein the moveable sub-component is shiftable along the first axis.

14 . The control panel device of claim 10 , wherein the moveable sub-component is pressable along a first axis among the at least one axis or along another axis.

15 . The control panel device of claim 10 , wherein the moveable sub-component is shiftable along a first axis among the at least one axis or along another axis.

16 . The control panel device of claim 10 , wherein the moveable sub-component is rotatable with respect to a first axis among the at least one axis, and is rotatable with respect to a second axis among the at least one axis.

17 . The control panel device of claim 1 , wherein the first surface represents a surface of a main part of the control panel device, and the magnetic component and the OTS are positioned within the main part; and the main part is arranged to display at least one indication corresponding to the at least one user input, wherein the at least one output comprises the at least one indication.

18 . The control panel device of claim 17 , wherein in addition to the magnetic component and the OTS, the main part of the control panel device further comprises a display panel of an electronic device, wherein the at least one indication is displayed on the display panel; and the moveable component is implemented as one or a combination of a knob and a button, for providing at least one corresponding function among knob and button functions with aid of the OTS.

19 . The control panel device of claim 17 , wherein in addition to the magnetic component and the OTS, the main part of the control panel device further comprises at least one visible light emitting device, wherein the at least one indication is displayed with the at least one visible light emitting device; and the moveable component is implemented as one or a combination of a knob and a button, for providing at least one corresponding function among knob and button functions with aid of the OTS.

20 . A method for providing human-machine interface with aid of optical detection, the method being applicable to a control panel device, the method comprising:
providing a magnetic component of the control panel device that is positioned below a first surface of the control panel device, and a moveable component of the control panel device that is positioned above the first surface, wherein the moveable component is magnetically attracted by the magnetic component to attach to the first surface; and utilizing an optical tracking sensor (OTS) of the control panel device that is positioned below the first surface to sense movement or rotation of the moveable component as at least one user input in order to generate at least one output corresponding to the at least one user input.
