Embodiment Construction
[0020] The method for prompting the motion direction and speed intensity of gestures in the interactive system of the present invention comprises the following steps: (1) starting up; (2) acquiring a section of image sequence by the sensor, and sending the section of image sequence to the computing module; (3) The calculation module calculates the motion direction and velocity intensity of the gesture in the image sequence, and compares the motion direction and velocity intensity of the gesture with the comparison scale respectively; (4) obtains the comparison result, and calculates the gesture according to the actual gesture motion direction and velocity. The intensity prompt is displayed.
[0021] Wherein, in step (3), the comparison scale is provided with a direction scale and a speed scale.
[0022] The detection method described in this embodiment is described in detail again below:
[0023] Such as figure 1 and figure 2 As shown in , this embodiment predefines 8 gest...

The invention discloses an indicating method for motion direction and speed strength of a gesture in an interaction system. The indicating method comprises the following steps of: (1) starting up; (2) acquiring a segment of image sequence and transmitting the image sequence to a calculation module by a sensor; (3) calculating the motion direction and the speed strength of the gesture in the segment of image sequence and respectively comparing the motion direction and the speed strength of the gesture with a comparison rule by the calculation module; and (4) obtaining the comparison result and promoting and displaying according to the actual motion direction and speed strength of the gesture. According to the indicating method for the motion direction and the speed strength of the gesture in the interaction system, which is disclosed by the invention, the motion direction and the speed strength of the gesture can be obtained accurately and quickly and further the interaction system makes an accurate reaction.
Description
technical field [0001] The invention relates to the field of human-computer interaction, in particular to a method for prompting the motion direction and velocity intensity of gestures in an interactive system. Background technique [0002] Gesture is a way of communication widely used by people in daily life, and has a strong expressive function. Most of the development of human-computer interaction technology also revolves around gestures, such as traditional mouse, keyboard, remote control, touch screen and so on. Some emerging gesture-based human-computer interaction methods use ordinary cameras or depth cameras as front-end sensors to capture image sequences of gestures moving in the air, and use image processing, machine learning, pattern recognition and other technologies to analyze the image sequences captured by the sensor Perform analysis and processing, recognize and track gestures, and interact with the interface to realize long-distance non-contact human-comput...
