Abstract

The present disclosure provides methods, apparatuses, and computer-readable mediums for performing ultra-wideband (UWB) remote control. In some embodiments, the method includes broadcasting an initial control request. The method further includes receiving, from one or more remote devices, at least one reply message comprising identification information and power spectrum information. The method further includes estimating, for each of the one or more remote devices, an angle indicating a pointing direction to that remote device relative to the remote control device. The method further includes determining a selected remote device that is being pointed at by the remote control device. The method further includes sending, to the one or more remote devices, a control signal comprising the identification information of the selected remote device and a control message indicating an action to be performed by the selected remote device.

First claim

What is claimed is:

1. A method of ultra-wideband (UWB) remote control to be performed by a remote control device, comprising:
broadcasting an initial control request;
receiving, from one or more remote devices in response to the initial control request, at least one reply message comprising identification information and power spectrum information of a corresponding remote device of the one or more remote devices, the power spectrum information having been generated based on at least the initial control request;
estimating, using a neural network-based algorithm, for each remote device of the one or more remote devices an angle indicating a pointing direction to that remote device relative to the remote control device, based at least on the power spectrum information;
determining, based at least on the angle of each remote device of the one or more remote devices, a selected remote device that is being pointed at by the remote control device; and
sending, to the one or more remote devices, a control signal comprising the identification information of the selected remote device and a control message indicating an action to be performed by the selected remote device.

2. The method of claim 1 , wherein the receiving of the at least one reply message comprises:
receiving, from the one or more remote devices in response to the initial control request, the at least one reply message, wherein the remote control device has not performed a pairing procedure with the one or more remote devices.

3. The method of claim 1 , further comprising:
detecting that a change in a pointing orientation of the remote control device exceeds a predetermined threshold,
wherein the broadcasting of the initial control request comprises broadcasting, in response to the detecting that the change in the pointing orientation of the remote control device exceeds the predetermined threshold, the initial control request.

4. The method of claim 1 , further comprising:
obtaining a user input indicating the action to be performed by the selected remote device,
wherein the broadcasting of the initial control request comprises broadcasting, in response to the obtaining of the user input, the initial control request.

5. The method of claim 1 , further comprising:
decoding, for each remote device of the one or more remote devices, respective signal phases of the at least one reply message;
generating coarse-grained angle estimates for each remote device of the one or more remote devices, based at least on the respective signal phases,
wherein the estimating of the angle comprises estimating, using the neural network-based algorithm, for each remote device of the one or more remote devices the angle indicating the pointing direction to that remote device relative to the remote control device, based at least on the power spectrum information and the coarse-grained angle estimates.

6. The method of claim 1 , further comprising:
displaying a control user interface (UI) corresponding to the selected remote device.

7. The method of claim 6 , wherein the sending of the control signal comprises:
obtaining, via the control UI, a user input indicating the action to be performed by the selected remote device.

8. The method of claim 6 , further comprising:
detecting that a change in a pointing orientation of the remote control device exceeds a predetermined threshold; and
changing display of the control UI to another control UI corresponding to another selected remote device, in response to the change in the pointing orientation of the remote control device causing the another selected remote device to be determined as the selected remote device.

9. The method of claim 1 , wherein the estimating of the angle comprises:
estimating, using the neural network-based algorithm, for each remote device of the one or more remote devices the angle indicating the pointing direction to that remote device in a two dimensional (2D) space or a three dimensional (3D) space relative to the remote control device, based at least on the power spectrum information.

10. The method of claim 1 , further comprising:
transmitting, to a particular remote device, a short preamble UWB signal at a predetermined power level, causing the particular remote device to calculate an environment-related parameter based on at least the short preamble UWB signal.

11. An apparatus for ultra-wideband (UWB) remote control to be performed by a remote control device, comprising:
a memory storage storing computer-executable instructions; and
a processor communicatively coupled to the memory storage, wherein the processor is configured to execute the computer-executable instructions and cause the apparatus to:
broadcast an initial control request;
receive, from one or more remote devices in response to the initial control request, at least one reply message comprising identification information and power spectrum information of a corresponding remote device of the one or more remote devices, the power spectrum information having been generated based on at least the initial control request;
estimate, using a neural network-based algorithm, for each remote device of the one or more remote devices an angle indicating a pointing direction to that remote device relative to the remote control device, based at least on the power spectrum information;
determine, based at least on the angle of each remote device of the one or more remote devices, a selected remote device that is being pointed at by the remote control device; and
send, to the one or more remote devices, a control signal comprising the identification information of the selected remote device and a control message indicating an action to be performed by the selected remote device.

12. The apparatus of claim 11 , wherein to receive the at least one reply message comprises to:
receive, from the one or more remote devices in response to the initial control request, the at least one reply message, wherein the remote control device has not performed a pairing procedure with the one or more remote devices.

13. The apparatus of claim 11 , wherein the processor is further configured to execute further computer-executable instructions and further cause the apparatus to:
detect that a change in a pointing orientation of the remote control device exceeds a predetermined threshold,
wherein to broadcast the initial control request comprises to broadcast, in response to detection that the change in the pointing orientation of the remote control device exceeds the predetermined threshold, the initial control request.

14. The apparatus of claim 11 , wherein the processor is further configured to execute further computer-executable instructions and further cause the apparatus to:
obtain a user input indicating the action to be performed by the selected remote device,
wherein to broadcast the initial control request comprises to broadcast, in response to obtaining of the user input, the initial control request.

15. The apparatus of claim 11 , wherein the processor is further configured to execute further computer-executable instructions and further cause the apparatus to:
decode, for each remote device of the one or more remote devices, respective signal phases of the at least one reply message;
generate coarse-grained angle estimates for each remote device of the one or more remote devices, based at least on the respective signal phases,
