Problems solved by technology

[0003] Each of these control techniques has the following disadvantages: for example, controlling the device by touching the touch screen often smudges the entire screen, and / or the device cannot be controlled by touching the touch screen if the user is wearing gloves
This lack of coherence creates a lot of inconvenience
Also, it is more inconvenient when the user tries to control a computer that the user is not familiar with

example 3

[0015] Example 3 shows the user's hand 112 at the end of the gesture, which is now generally perpendicular to the display 108 . Also, when compared to Example 1, the content 110 has scrolled down. Also note that in Examples 1-3 the user does not need to physically touch the computer to perform the control functions.

[0016] As mentioned above, the computer 102 includes a speaker 104 and a microphone 106 . The speaker and microphone can be dedicated hardware devices used only for the user gesture detection function. However, this need not be the case. In fact, most computers already include at least one microphone and at least one speaker. These existing hardware devices can be utilized to reduce the complexity and cost involved in adding additional hardware devices. Furthermore, existing speakers and microphones can implement the present gesture detection functionality without interrupting or impairing the existing use of the device. For example, assume that in Example 1...

Abstract

The invention discloses user control gesture detection. In one embodiment, a loudspeaker and a microphone are allowed to execute a first function. The embodiment also utilizes the loudspeaker and the microphone to perform the second function. The second function includes utilizing the microphone to capture sound signals from the loudspeaker and detecting Doppler frequency shift in the sound signals. The user control gesture executed near a computer is correlated with Doppler frequency shift and the user control gesture is reflected to a control function.

Description

technical field [0001] The present disclosure relates to user control gesture detection. Background technique [0002] Computers are ubiquitous in our daily life. Users tend to own or interact with many different computers rather than having "one computer". For example, in general, a user may have a desktop computer at work, a laptop computer, smart phone, tablet computer, video game console, and / or e-book at home, and so on. In addition, users often interact with other computers integrated into other devices. For example, a user's car may have a computer with which the user interacts to get directions, listen to music, and so on. A variety of different user controls have been developed for these different types of computers. For example, mice and physical keyboards tend to be the most common ways of controlling and interacting with desktop computers. For notebook computers, the mouse is not very convenient, and it usually uses a touchpad type device instead of the mous...
