Drawings
Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:
fig. 1 is a flowchart illustrating steps of a gesture synchronous detection control method according to the present invention.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The gesture synchronous detection control method provided by the invention comprises the following steps:
a motion information acquisition step: acquiring motion information of the mobile terminal; the mobile terminal can be a handheld terminal such as a smart phone, a smart watch, a tablet computer, smart glasses, a smart bracelet, a smart toy, a smart remote controller and the like. The user holds the handheld terminal, can change the gesture of the mobile terminal through actions such as tilting, and meanwhile, the user holds the handheld terminal, and drives the mobile terminal to make gestures along with the hand through actions such as rotating the wrist and waving the arm. The mobile terminal generates motion information when changing the posture and making a gesture, or when the posture is kept unchanged, the motion information is considered as representing that the mobile device is in a static motion state relative to the hand of the user and is also used as the motion information. In this way, the four kinds of motion information, that is, the motion information that both of the gesture and the posture are changed, neither of the gesture and the posture is changed, one of the gesture and the posture is changed, the other of the gesture and the posture is not changed, and the other of the gesture and the posture is not changed can be simply arranged and combined. Accordingly, the four kinds of motion information can allow the user to correspondingly issue four kinds of control instructions. In a preferred example, the mobile terminal is an intelligent wearable device, for example, an intelligent wearable device worn on a forearm, and a posture of the intelligent wearable device corresponds to a posture of the forearm of the wearer, so that according to the posture of the intelligent wearable device, a posture of a body part of the wearer can be obtained as the posture information to enter subsequent analysis and control.
And (3) attitude analysis: analyzing to obtain attitude information according to the motion information; the gesture information reflects a small amplitude movement of the user, which may typically be a wrist movement, such as tilting or shaking.
A gesture analysis step: analyzing to obtain gesture information according to the motion information; the gesture information reflects the large range of movements of the user, which usually require the cooperation of the elbow joint and the shoulder joint. In particular, the mobile terminal is regarded as a mass point, and the motion track of the mass point is taken as a gesture.
And (3) controlling and analyzing: and obtaining control information according to the gesture information and the posture information. According to the invention, instead of obtaining one control information by gesture information and another control information by attitude information, the control information is obtained according to the combination of the gesture information and the attitude information at the same time or in the same time period. Wherein the same time period may be a time period between a start time and an end time of making a full gesture. For example, when the gesture information is satisfactory, i.e., the gesture is considered to be standard, and the posture information is unsatisfactory, i.e., the posture is considered to be not standard, the combination of the satisfactory gesture information and the satisfactory posture information cannot be obtained, and the control information desired by the user cannot be generated.
The present invention will be described in more detail below.
The motion information comprises acceleration sensing information, wherein the acceleration sensing information indicates an acceleration of the mobile terminal; the acceleration sensing information is acquired through an acceleration sensor in the mobile terminal. In the attitude analysis step, extracting an acceleration component related to the attitude from the acceleration sensing information, and recording the acceleration component as an attitude acceleration component; and matching the attitude acceleration component with attitude preset information to obtain attitude information. In the gesture analysis step, extracting an interference acceleration component of the attitude acceleration component from the acceleration sensing information, and recording the interference acceleration component as a gesture acceleration component; and matching the gesture acceleration component with gesture preset information to obtain gesture information. More specifically, the acceleration sensor may be one or several. For a mobile terminal having only one acceleration sensor, patent document CN107014386B discloses a solution capable of separating acceleration related to the attitude of an aircraft from acceleration unrelated to the attitude, and those skilled in the art can extract and separate acceleration components corresponding to attitude information and gesture information at least with reference to patent document CN 107014386B. For a mobile terminal having a plurality of, for example, two, acceleration sensors, acceleration information corresponding to each of the posture information and the gesture information may be acquired by the two acceleration sensors.
Further, in the gesture analysis step, the gesture acceleration component is matched with gesture preset information to obtain gesture information, then correction information corresponding to the gesture information is found, and the gesture information is corrected by using the correction information; wherein the correction information is used for correcting acceleration deviation caused by action deviation caused by limitation of human joint activity. In a preferred embodiment, the attitude preset information is a set of acceleration component templates, and the attitude information corresponding to the template in the set of acceleration component templates that is most matched with the attitude acceleration component is preset and used as the attitude information obtained after the attitude acceleration component is matched. However, due to the limitation of the mobility of the joints of the human body, especially the limitation of the wrist joints and elbow joints of the hand, it is difficult to make the desired movements in various directions, which is also related to the flexibility of the arm of the user, or it is difficult to exert force at some angles, etc. Therefore, the invention corrects the acceleration deviation caused by the action deviation caused by the limitation of the joint mobility of the human body so as to correct the slightly nonstandard action made by the user into the standard action, thereby facilitating the matching calculation of a subsequent computer and avoiding misjudgment. The types of the action deviation and the correction value of the action deviation of each type are preset and form a table, and the computer can obtain a correction scheme corresponding to the corresponding action deviation in a table look-up mode to correct the action deviation.
More specifically, in the control analysis step, according to the gesture information and the posture information, a current combination relationship of the gesture postures is obtained, and according to the current combination relationship, a corresponding control instruction is obtained, wherein the control instruction instructs the actuator to execute a preset action. For example, if the current combination relationship is that the gesture draws a circle and the posture is always kept horizontal, the corresponding control command is obtained to command the toy car to stop moving forward, and the toy car as the actuator executes the preset action of parking. For another example, if the current combination is that the gesture is drawing a 8-word, and the gesture is left-right shaking, then the corresponding control command is obtained to command the toy vehicle to accelerate forward according to the 8-word. In a preferred example, the current combination relationship includes a position relationship, where the position relationship is used to indicate a position of the mobile terminal in the gesture motion when the gesture posture is generated. For example, the current combination relationship including the position relationship is that the gesture draws a triangle, the gesture at the top corner of the triangle is forward tilting, the gesture at the left lower corner of the triangle is leftward tilting, and the gesture at the right lower corner of the triangle is rightward tilting, so that the corresponding control command is obtained as playing music.
