Abstract

Gestures allow selection and alteration of media files. A video file is graphically illustrated on a touch sensitive display. A gesture input is received at a point of contact on the touch sensitive display and ends with disengagement of the touch sensitive display. A vector is determined from the point of contact to the disengagement of the touch sensitive display. The video file is then modified in response to the vector.

First claim

The invention claimed is:

1. A method, comprising:
receiving, by a hardware processor, a single stream of input data representing a single contiguous gesture to a touch sensitive display, the single stream of input data describing an initial point of a contact with a linear representation of a video file displayed by the touch sensitive display, a final point of a disengagement from the touch sensitive display, and multiple vector components representing the single contiguous gesture from the initial point of the contact to the final point of the disengagement;
generating, by the hardware processor, a default selection having a midpoint along the linear representation of the video file in response to the single stream of input data describing the initial point of the contact;
receiving, by the hardware processor, a first vector component of the multiple vector components representing the single contiguous gesture, the first vector component associated with a first pre-defined command to temporally and equally expand boundaries of the default selection from the midpoint to generate an expanded default selection;
receiving, by the hardware processor, a second vector component of the multiple vector components representing the single contiguous gesture, the second vector component associated with a second pre-defined command to shift the midpoint and the expanded default selection forward in time along the linear representation of the video file;
receiving, by the hardware processor, the single stream of input data describing the disengagement from the touch sensitive display, the single stream of input data describing the disengagement associated with a third pre-defined command to trim an unselected portion of the linear representation of the video file.

2. The method of claim 1 , further comprising trimming the video frames that correspond to the unselected portion of the linear representation of the video file.

3. The method of claim 1 , further comprising associating a tag to the expanded default selection shifted forward in time after the third pre-defined command to trim.

4. The method of claim 1 , further comprising associating a default tag to the expanded default selection shifted forward in time after the third pre-defined command to trim.

5. The method of claim 1 , further comprising generating a prompt for a user input in response to the single stream of input data describing the final point of the disengagement.

6. The method of claim 1 , further comprising tagging a date and time to the expanded default selection shifted forward in time after the third pre-defined command to trim.

7. The method of claim 1 , further comprising comparing the multiple vector components to a library of gestures.

8. A system, comprising: a hardware processor; and a memory device, the memory device storing code, the code when executed causing the hardware processor to perform operations, the operations comprising:
receiving a single stream of input data representing a single contiguous gesture to a touch sensitive display, the single stream of input data describing an initial point of a contact with a linear representation of a video file displayed by the touch sensitive display, a final point of a disengagement from the touch sensitive display, and multiple vector components representing the single contiguous gesture from the initial point of the contact to the final point of the disengagement;
generating a default selection having a midpoint along the linear representation of the video file in response to the single stream of input data describing the initial point of the contact; receiving a first vector component of the multiple vector components representing the single contiguous gesture, the first vector component associated with a first pre-defined command to temporally and equally expand boundaries of the default selection from the midpoint to generate an expanded default selection; receiving a second vector component of the multiple vector components representing the single contiguous gesture, the second vector component associated with a second pre-defined command to shift the midpoint and the expanded default selection forward in time along the linear representation of the video file;
receiving the single stream of input data describing the disengagement from the touch sensitive display, the single stream of input data describing the disengagement associated with a third pre-defined command to trim an unselected portion of the linear representation of the video file.

9. The system of claim 8 , wherein the operations further comprise trimming video frames that correspond to the unselected portion of the linear representation of the video file.

10. The system of claim 8 , wherein the operations further comprise associating a tag to the expanded default selection shifted forward in time after the third pre-defined command to trim.

11. The system of claim 8 , wherein the operations further comprise generating a prompt for a user to input a description of the expanded default selection shifted forward in time after the third pre-defined command to trim.

12. The system of claim 8 , wherein the operations further comprise associating a default tag to the expanded default selection shifted forward in time after the third pre-defined command to trim.

13. The system of claim 8 , wherein the operations further comprise tagging a date and time to the expanded default selection shifted forward in time after the third pre-defined command to trim.

14. The system of claim 8 , wherein the operations further comprise comparing the multiple vector components to a library of gestures.

15. A non-transitory memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
receiving a single stream of input data representing a single contiguous gesture to a touch sensitive display, the single stream of input data describing an initial point of a contact with a linear representation of a video file displayed by the touch sensitive display, a final point of a disengagement from the touch sensitive display, and multiple vector components representing the single contiguous gesture from the initial point of the contact to the final point of the disengagement; generating a default selection having a midpoint along the linear representation of the video file in response to the single stream of input data describing the initial point of the contact; receiving a first vector component of the multiple vector components representing the single contiguous gesture, the first vector component associated with a first pre-defined command to temporally and equally expand boundaries of the default selection from the midpoint to generate an expanded default selection; receiving a second vector component of the multiple vector components representing the single contiguous gesture, the second vector component associated with a second pre-defined command to shift the midpoint and the expanded default selection forward in time along the linear representation of the video file;
receiving the single stream of input data describing the disengagement from the touch sensitive display, the single stream of input data describing the disengagement associated with a third pre-defined command to trim an unselected portion of the linear representation of the video file.
