Abstract

A multi-stage gesture control method and device. The method and device implement multi-stage gesture control using multi-touch sliding.

Description

Multi-level gesture control method and device

Field of invention

The present invention relates to a multi-level gesture control method and apparatus, and in particular to a multi-level gesture control method and apparatus that utilizes sliding under multi-touch.

Background technique

Since Apple released the iPhone in 2007, gesture control has spread to the extent that there is no way for the elderly and children, and a new era of human-computer interaction has arrived. Based on this era, we found that many control methods are too cumbersome:

• Regular audio and video playback control is performed via a remote control or a computer keyboard. The computer keyboard is too cumbersome, and the remote control is too cumbersome for applications that need to frequently switch audio and video sources.

• Regular radio/television makes jumps/channels with knobs and remote controls. For more than 50 broadcast/TV channels today, either jump one by one or remember channel numbers, which is extremely slow. Although TV can't be broadcasted on demand, consumers sometimes need to browse through the programs on each channel. However, digital broadcast/TV is sorted according to certain classifications. Users sometimes need to jump directly to a certain channel interval, and then browse this one by one. The current program in the channel section.

We can use multi-touch to achieve multi-level fast forward/rewind of audio and video playback, and multi-level platform for radio/television remote control:

· Single point left/right slip, each rewind / fast forward 10"; double point left / right slide, each rewind / fast forward 1 '; three left / right slide, each rewind / fast forward 10 '

· Single left/right slide, one fast rewind/fast forward 1 channel; double left/right slide, each fast rewind/fast forward 5 channels; three o'clock left/right slide, each rewind/fast Into 10 channels

Summary of invention

Devices that can sense touch, such as touchpads/touchscreens, are now supported or already support multi-touch. We can achieve a universal control method for multi-level gestures through multi-touch.

The lowest level change amount is taken as a constant, and the other level change amount is a multiple of the constant:

· Single point left/right slip, reducing/increasing 1 unit control variable each time

·Double-point left/right slip, each rewind/fast forward 5 unit control variable

The direction of the slide, as well as the change factor of the different levels of control variables, can be customized by the consumer according to their own habits.

However, it is to be understood that the invention is not intended to be limited or limited by the scope of the invention, and the invention disclosed herein The skilled artisan includes significant improvements and modifications thereto.

Detailed ways

The invention will now be described more fully hereinafter. However, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. The present invention is intended to be thorough and complete, and the scope of the invention will be fully conveyed by those skilled in the art.

It will be appreciated that various changes can be made in the function and arrangement of the elements without departing from the spirit and scope of the invention. Thus, embodiments are examples or implementations of the invention, not the only implementation. The appearances of "one embodiment", "an embodiment" or "an embodiment" are not necessarily referring to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may be provided separately or in any suitable combination. Conversely, although the invention may be described herein in the context of a separate embodiment, the invention may be practiced in a single embodiment or any combination of the embodiments.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the related art and the present disclosure, and will not be construed as idealized or excessive. Formal meaning, unless explicitly defined in this article.

Reference Terms such as "Left", "Right", "Top", "Bottom", "Front" and "After" are intended to be used in the practice of the present invention in relation to the particular features, structures or elements in the depicted embodiments. example. Obviously, this directional term for the actual use of the device has no specific meaning, as the device can be used by the user or multiple users in multiple directions.

The invention discloses a multi-level gesture control method and device, and an embodiment thereof mainly focuses on a touch screen and a touch panel. However, embodiments of the invention are not limited to dedicated gesture control devices. For example, through a mobile phone or a tablet computer, multi-screen interaction with a device such as a television can also utilize the technical solution described below, such as using a mobile phone as a gesture control device.

In order to distinguish the direction of the jump channel, and other playback control gestures, it is necessary to determine the sliding direction. We assume that when the user slides the finger, it does not exactly follow the absolute horizontal direction. Then the sliding trajectory can be decomposed into moving components in both horizontal and vertical directions.

If the horizontal movement is greater than the vertical movement and is to the left, slide to the left to perform the negative control variable of the corresponding level; if the horizontal movement is greater than the vertical movement and to the right, slide to the right to perform the positive control of the corresponding level. variable.

In general, three levels of gesture control are sufficient, and for smaller touch control devices (such as the touchpad of a regular notebook), the space for five fingers to slide is too narrow to slide the highest level to the left (four The finger swipe is set to the previous variable value of the current control variable, and the previous variable value of the current control variable is the previous variable value relative to the current broadcast control variable among the change amount history. The same can be used to define the next highest level gesture control.

The above description is only an embodiment of the invention and is not intended to limit the scope of the invention. Various changes and modifications of the claims and the description of the present invention are still within the scope of the claimed invention. Moreover, each of the embodiments and claims does not necessarily include all of the advantages or features disclosed.
