Abstract

Systems and methods are disclosed for adaptation of presentation speed for content presentation (e.g., audio content presentation). For example, methods may include obtaining an indication of motion in a space; adjusting a presentation speed based on the indication of motion; and presenting a content item associated with a location in the space, wherein the content item is presented using the adjusted presentation speed.

Claims

1. A system for audio presentation, comprising:

a motion sensor;

a speaker;

a memory; and

a processor, wherein the memory stores instructions executable by the processor to cause the system to;

identify audio content associated with a location in a space, the audio content having a primary presentation speed;

obtain, from the motion sensor, an indication of a rate of motion in the space of a user relative to the location;

determine an adjusted presentation speed based on the rate of motion and the primary presentation speed; and

present, via the speaker, the audio content to the user in accordance with the adjusted presentation speed.

2. The system of claim 1, comprising a wearable display and wherein the memory stores instructions executable by the processor to cause the system to:

present, via the wearable display, video content synchronously with the audio content.

3. The system of claim 1, comprising an eye tracking sensor and wherein the memory stores instructions executable by the processor to cause the system to:

obtain, form the eye tracking sensor, an indication of gaze direction for a user; and

wherein the adjusted presentation speed is determined based in part on the indication of gaze direction.

4. The system of claim 1, wherein the memory stores instructions executable by the processor to cause the system to:

determine a user position in the space;

check whether the user position is in proximity to the location; and

initiate presentation of the audio content in response to a determination that a proximity of the user to the location changes from greater than a defined proximity threshold to within the defined proximity threshold.

5. The system of claim 1, wherein the instructions executable by the processor to cause the system to:

determine a time period of proximity between the user and a prior location in the space, wherein the prior location is associated with a prior content item, wherein the prior content item has a duration;

determine a ratio of the time period to the duration; and

determine the adjusted presentation speed based on the ratio.

6. The system of claim 5, wherein the instructions executable by the processor to cause the system to:

determine the adjusted presentation speed to be inversely proportional to the ratio within a range between a minimum presentation speed and a maximum presentation speed.

7. A system for content presentation, comprising:

a memory; and

a processor, wherein the memory stores instructions executable by the processor to cause the system to;

identify a content item associated with a location in a space, the content item having a primary presentation speed;

obtain an indication of a rate of motion in the space of a user relative to the location;

determine an adjusted presentation speed based on the rate of motion and the primary presentation speed; and

present the content item to the user in accordance with the adjusted presentation speed.

8. The system of claim 7, wherein the instructions include instructions executable by the processor to cause the system to:

receive motion data from a motion sensor; and

obtain the indication of the rate of motion based on the motion data.

9. The system of claim 7, wherein the instructions include instructions executable by the processor to cause the system to:

receive image data from a camera, wherein the image data includes views of a user moving in the space; and

obtain the indication of the rate of motion based on received image data.

10. The system of claim 7, wherein the instructions include instructions executable by the processor to cause the system to:

determine the adjusted presentation speed such that the adjusted presentation speed is less than a limit.

11. The system of claim 7, wherein the memory stores instructions executable by the processor to cause the system to:

determine a user position in the space;

check whether the user position is in proximity to the location; and

initiate presentation of the content item in response to a determination that a proximity of the user to the location changes from greater than a defined proximity threshold to within the defined proximity threshold.

12. The system of claim 7, wherein the instructions include instructions executable by the processor to cause the system to:

determine a time period of proximity between the user and a prior location in the space, wherein the prior location is associated with a prior content item, wherein the prior content item has a duration;

determine a ratio of the time period to the duration; and

determine the adjusted presentation speed based on the ratio.

13. The system of claim 12, wherein the instructions include instructions executable by the processor to cause the system to:

determine the adjusted presentation speed to be inversely proportional to the ratio within a range between a minimum presentation speed and a maximum presentation speed.

14. The system of claim 7, wherein the space is a virtual space.

15. The system of claim 7, wherein the space is a real space.

16. The system of claim 7, wherein the content item includes at least one of audio content, video content, or slideshow content.

17. The system of claim 7, wherein the memory stores instructions executable by the processor to cause the system to:

obtain an indication of gaze direction for the user; and

wherein the adjusted presentation speed is determined based in part on the indication of gaze direction.

18. A method for content presentation comprising:

identifying a content item associated with a location in a space, the content item having a primary presentation speed;

obtaining an indication of a rate of motion in a the space of a user relative to the location;

determining, by a processor an adjusted presentation speed based on the rate of motion and the primary presentation speed; and

presenting the content item to the user in accordance with the adjusted presentation speed.

19. The method of claim 18, comprising:

determining a user position in the space;

checking whether the user position is in proximity to the location; and

initiating presentation of the content item in response to a determination that a proximity of the user to the location changes from greater than a defined proximity threshold to within the defined proximity threshold.

20. The method of claim 18, wherein determining the adjusted presentation speed comprises:

determining a time period of proximity between the user and a prior location in the space, wherein the prior location is associated with a prior content item, wherein the prior content item has a duration;

determining a ratio of the time period to the duration; and

determining the adjusted presentation speed based on the ratio.
