User interface for a portable device including detecting close proximity of an ear to allow control of an audio application with a touchscreen
View Patent ↗In a portable electronic device such as a mobile phone with a touchscreen display and a camera, if the camera detects that the user's ear is near the touchscreen (indicating that the user is using an audio application such as a phone call, radio player, music player, etc.) then the touchscreen can accept a touch or swipe from the user's ear, head, cheek or adjacent area. The adapted input can allow the user to control the audio application such as by swiping to change the volume, channel, song, etc.
1. A method comprising:
detecting that an ear is in proximity to a portable electronic device;
determining that an audio function is being executed on the portable electronic
device; and accepting a signal from a touch screen on the portable electronic device to control the audio application, wherein the signal is generated at least in part by the ear touching the touch screen, wherein enabled controls for a detected ear control mode of the audio application are different from a non-ear control mode.
2. The method of claim 1 , further comprising:
using a camera on the portable electronic device to take a picture of the ear; and
analyzing the picture to conclude that the ear is within a predetermined distance of the portable electronic device.
3. The method of claim 1 , wherein the portable electronic device includes a mobile phone.
4. The method of claim 1 , wherein the audio function includes a phone call.
5. The method of claim 4 , wherein the control of the audio application in response to the ear touching the touch screen includes ending the phone call.
6. The method of claim 4 , wherein the control of the audio application in response to the ear touching the touch screen includes muting the phone call.
7. The method of claim 1 , wherein the audio function includes a radio.
8. The method of claim 7 , wherein the control of the audio application in response to the ear touching the touch screen includes changing to a different radio program.
9. The method of claim 1 , wherein the audio function includes audio playback.
10. The method of claim 9 , wherein the control of the audio application in response to the ear touching the touch screen includes changing the audio playback to a new song.
11. The method of claim 1 , wherein the signal from the touch screen is used to control an audio volume.
12. The method of claim 11 , further comprising:
adjusting the audio volume according to a hardness of pressing of the ear against the touchscreen.
13. The method of claim 11 , further comprising:
adjusting the audio volume according to a swipe of the ear against the touchscreen.
14. The method of claim 1 , wherein the signal from the touch screen is used to control a channel selection.
15. An apparatus comprising: a portable electronic device;
a digital processor included in the portable electronic device, wherein the digital processor is responsive to instructions for:
detecting that an ear is in proximity to a portable electronic device;
determining that an audio function is being executed on the portable electronic
device; and
accepting a signal from a touch screen on the portable electronic device to control the audio application, wherein the signal is generated at least in part by the ear touching the touch screen, wherein enabled controls for a detected ear control mode of the audio application are different from a non-ear control mode.
16. The apparatus of claim 15 , wherein the instructions include:
adjusting a volume of the audio function according to a hardness of pressing of the ear against the touchscreen.
17. The apparatus of claim 15 , wherein the instructions include:
adjusting a volume of the audio function according to a swipe of the ear against the touchscreen.
18. A processor-readable non-transitory medium including one or more instructions for:
detecting that an ear is in proximity to a portable electronic device;
determining that an audio function is being executed on the portable electronic
device; and
accepting a signal from a touch screen on the portable electronic device to control the audio application, wherein the signal is generated at least in part by the ear touching the touch screen,
wherein enabled controls for a detected ear control mode of the audio application are different from a non-ear control mode.
19. The processor-readable non-transitory medium of claim 18 , wherein the one or more instructions includes:
adjusting a volume of the audio function according to a hardness of pressing of the ear against the touchscreen.
20. The processor-readable non-transitory medium of claim 18 , wherein the one or more instructions includes:
adjusting a volume of the audio function according to a swipe of the ear against the touchscreen.
