Abstract

The present disclosure relates to a method performed by a mobile device for facilitating inputting a command to a service application in the mobile device. The mobile device comprises an inertial measurement unit (IMU). The method comprises determining a time interval in which a user of the mobile device will agitate the mobile device in accordance with a command. The method also comprises filtering an information feed from the IMU during said time interval to remove signals which are outside of a predetermined spectrum and thus regarded as noise. The method comprises finding distinguishable signals within the filtered feed, said distinguishable signals forming a command pattern. The method comprises associating the command pattern with the command.

Claims

1. A method performed by a mobile device for facilitating inputting a command to a service application in the mobile device, the mobile device comprising an inertial measurement unit (IMU) the method comprising:

determining a time interval in which a user of the mobile device will agitate the mobile device in accordance with a command;

filtering an information feed from the IMU during said time interval to remove signals which are outside of a predetermined spectrum and thus regarded as noise;

finding distinguishable signals within the filtered feed, said distinguishable signals forming a command pattern; and

associating the command pattern with the command.

2. The method of claim 1, further comprising:

after the associating of the command pattern with the command, continuously filtering the feed from the IMU to remove signals which are outside of the predetermined spectrum;

identifying distinguishable signals within the continuously filtered feed which conform with the command pattern; and

in response to the identifying, presenting the command to the service application.

3. The method of claim 1, wherein the service application is an application for media streaming.

4. The method of claim 1, wherein the command is a command for controlling media streaming of the service application.

5. The method of claim 1, wherein the filtering comprises removing signals having a frequency below a predetermined frequency threshold.

6. The method of claim 1, wherein the filtering comprises removing signals which the radio device has been trained to regard as noise.

7. The method of claim 1, wherein the method is implemented by the service application.

8. The method of claim 1, wherein the method is implemented by a helper application in the mobile device, separate from the service application.

9. The method of claim 1, wherein the command pattern corresponds to the user agitating the mobile device by tapping it.

10. The method of claim 1, wherein the step of finding signals comprises using a Support Vector Machine (SVM) model.

16. A computer program product comprising computer-executable components for causing a mobile device to perform the method of claim 1 when the computer-executable components are run on processor circuitry comprised in the mobile device.

11. A mobile device comprising:

an inertial measurement unit (IMU);

a service application;

processor circuitry; and

a storage unit storing instructions executable by said processor circuitry whereby said mobile device is operative to;

determine a time interval in which a user of the mobile device will agitate the mobile device in accordance with a command to the service application;

filter an information feed from the IMU during said time interval to remove signals which are outside of a predetermined spectrum and thus regarded as noise;

find distinguishable signals within the filtered feed, said distinguishable signals forming a command pattern; and

associate the command pattern with the command.

12. The mobile device of claim 11, further operative to:

after the associating of the command pattern with the command, continuously filter the feed from the IMU to remove signals which are outside of the predetermined spectrum;

identify distinguishable signals within the continuously filtered feed which conform with the command pattern; and

in response to the identifying, present the command to the service application.

13. The mobile device of claim 11, wherein the IMU comprises accelerometers and a gyroscope.

14. The mobile device of claim 11, wherein the mobile device is a radio device.

15. The mobile device of claim 14, wherein the radio device is a smartphone.

17. A non-transitory computer readable storage medium, including an application software for a mobile device comprising an inertial measurement unit (IMU), the software comprising computer program code which is able to, when run on processor circuitry of the mobile device, cause the mobile device to:

determine a time interval in which a user of the mobile device will agitate the mobile device in accordance with a command to a service application in the mobile device;

filter an information feed from the IMU during said time interval to remove signals which are outside of a predetermined spectrum and thus regarded as noise;

find distinguishable signals within the filtered feed, said distinguishable signals forming a command pattern; and

associate the command pattern with the command.

18. The non-transitory computer readable storage medium including the application software of claim 17, wherein the code is also able to cause the mobile device to:

after the associating of the command pattern with the command, continuously filter the feed from the IMU to remove signals which are outside of the predetermined spectrum;

identify distinguishable signals within the continuously filtered feed which conform with the command pattern; and

in response to the identifying, present the command to the service application.

19. The non-transitory computer readable storage medium including the application software of claim 17, wherein the application software is comprised in the service application.

20. The non-transitory computer readable storage medium including the application software of claim 17, wherein the application software is comprised in a helper application in the mobile device.
