Abstract

Systems, storage medium, and methods associated with adaptive visual output on a mobile device are disclosed herein. In embodiments, a storage medium may have instructions to enable the mobile device to determine a change in a distance between the mobile device and a user of the mobile device. The instruction may also enable the mobile device to operate an end-user application that may adaptively present a visual output based at least in part on a result of the change in the distance. Other embodiments may be disclosed or claimed.

Claims

1. One or more non-transitory computer-readable media having instructions that, in response to execution by a mobile device, cause the mobile device to:

determine a first change in distance between the mobile device and a user of the mobile device;

operate a camera application associated with a camera coupled with the mobile device that adaptively presents a visual output based at least in part on the first change in distance, wherein to operate the camera application includes recalibrating a zoom level of the camera application based at least in part on the first change in distance;

determine a user-specific maximum distance between the mobile device and the user, based on a second change in distance;

determine a user-specific minimum distance between the mobile device and the user, based on the second change in distance;

calibrate a zoom per distance resolution for the camera application based on at least one of the maximum or the minimum distance; and

operate the camera application to change a zoom level of the camera application or to cause a change to a zoom level of the camera based on the second change in distance.

2. The one or more computer-readable media of claim 1, wherein calibrate the zoom per distance resolution includes:

determine that a maximum zoom of the camera application or the camera will occur before the user-specific maximum distance will occur during a displacement of the mobile device;

adjust the zoom per distance resolution, in response to the determination that the maximum zoom will occur before the user-specific maximum distance will occur; and

save the adjusted zoom per distance resolution to an account for the user.

3. The one or more computer-readable media of claim 1, wherein the instructions are further configured to:

discontinue change of the zoom level of the camera application or the camera in response to movement of the mobile device in a direction that is opposite to a direction associated with the second change in distance;

or

discontinue change of the zoom level of the camera application or the camera in response to reaching a maximum zoom level or a minimum zoom level of the camera application or the camera.

4. A method comprising:

determining, by a mobile device, a first change in distance between the mobile device and a user of the mobile device;

operating, by the mobile device, a camera application associated with a camera coupled with the mobile device that adaptively presents a visual output based at least in part on the first change in distance, wherein to operate the camera application includes recalibrating a zoom level of the camera application based at least in part on the first change in distance;

determining, by the mobile device, a user-specific maximum distance between the mobile device and the user, based on a second change in distance;

determining, by the mobile device, a user-specific minimum distance between the mobile device and the user, based on the second change in distance;

calibrating, by the mobile device, a zoom per distance resolution for the camera application based on at least one of the maximum or the minimum distance; and

operating, by the mobile device, the camera application to change a zoom level of the camera application or to cause a change to a zoom level of the camera based on the second change in distance.

5. The method of claim 4, wherein calibrating the zoom per distance resolution includes:

determining, by the mobile device, that a maximum zoom of the camera application or the camera will occur before the user-specific maximum distance will occur during a displacement of the mobile device;

adjusting, by the mobile device, the zoom per distance resolution, in response to the determination that the maximum zoom will occur before the user-specific maximum distance will occur; and

saving, by the mobile device, the adjusted zoom per distance resolution to an account for the user.

6. The method of claim 5, further comprising:

discontinuing, by the mobile device, change of the zoom level of the camera application or the camera in response to movement of the mobile device in a direction that is opposite to a direction associated with the second change in distance;

or

discontinuing, by the mobile device, change of the zoom level of the camera application or the camera in response to reaching a maximum zoom level or a minimum zoom level of the camera application or the camera.

7. An apparatus comprising:

means for determining a first change in distance between a mobile device and a user of the mobile device;

means for operating a camera application associated with a camera coupled with the mobile device that adaptively presents a visual output based at least in part on the first change in distance, wherein to operate the camera application includes recalibrating a zoom level of the camera application based at least in part on the first change in distance;

means for determining a user-specific maximum distance between the mobile device and the user, based on a second change in distance;

means for determining a user-specific minimum distance between the mobile device and the user, based on the second change in distance;

means for calibrating a zoom per distance resolution for the camera application based on at least one of the maximum or the minimum distance; and

means for operating the camera application to change a zoom level of the camera application or to cause a change to a zoom level of the camera based on the second change in distance.

8. The apparatus of claim 7, wherein calibrating the zoom per distance resolution includes:

means for determining that a maximum zoom of the camera application or the camera will occur before the user-specific maximum distance will occur during a displacement of the mobile device;

means for adjusting the zoom per distance resolution, in response to the determination that the maximum zoom will occur before the user-specific maximum distance will occur; and

means for saving the adjusted zoom per distance resolution to an account for the user.

9. The apparatus of claim 8, further comprising:

means for discontinuing change of the zoom level of the camera application or the camera in response to movement of the mobile device in a direction that is opposite to a direction associated with the second change in distance;

or

means for discontinuing change of the zoom level of the camera application or the camera in response to reaching a maximum zoom level or a minimum zoom level of the camera application or the camera.
