Description
Technical Field
The invention relates to the field of mice, in particular to a ring type mouse capable of prejudging a two-finger combination trend and a terminal control method thereof.
Background
Common terminals include desktop computers, notebook computers, smart phones, tablet computers, smart televisions, smart watches, smart projectors, smart glasses with a display function, and the like. With the development of portable terminals, people have made higher and higher requirements on the portability of peripheral devices of operation terminals, wherein the most common peripheral devices are a keyboard and a mouse, and the most portable keyboard at present is a film rollable keyboard and a projection keyboard, but for the mouse, although manufacturers are also promoting light and thin mice, the portability is still insufficient. Particularly, after the 5G era comes, the gradual popularization of cloud computers enables mobile phones and intelligent glasses to be used as computers slowly, but if a traditional mouse is carried when the mobile phones or the intelligent glasses are used for mobile office, a very smooth picture is obtained, and therefore a more miniature and portable peripheral capable of replacing the traditional mouse is urgently needed.
In order to solve the above problems, the inventor has previously filed two patent applications with patent names of "a ring mouse", application number of "2019109515241", and patent names of "a method for controlling a terminal of a ring mouse", and application number of "2019109515237" to the national patent office, and the two patent applications propose a ring mouse and a method for controlling a terminal thereof, wherein all functions of the conventional mouse are integrated on a simple ring, and after the ring mouse is worn, all operations of the conventional mouse, including clicking, double clicking, right clicking, cursor moving, dragging, roller rolling, middle mouse key pressing and middle mouse key dragging, can be completed by two fingers.
In the product development and test process of the ring-type mouse, the inventor finds a small problem, which is described as follows: if the wearing finger is separated from the adjacent finger, the gesture operation of moving the wearing finger along the working surface of the mouse is defined as cursor movement; defining the gesture that the two fingers perform single click together in a state that the wearing finger and the adjacent finger are combined as right click; in this case, when the pointing right-click operation is performed after the operation cursor is moved to a certain position, since the state between the wearing finger and the adjacent finger needs to be switched from the separated state to the combined state, in this switching process, due to the limitation of the operation flexibility of the fingers of a common person, it is difficult to move only the adjacent finger and keep the wearing finger still, the wearing finger inevitably moves, and the movement of the wearing finger causes the optical positioning sensor to move relative to the working surface of the mouse, so that the cursor on the controlled terminal also moves. Therefore, in this case, to implement the fixed-point right click, only after the operating cursor moves to a certain position, the two operating fingers are lifted slightly to make the distance between the optical position sensor and the working surface of the mouse exceed the silent distance, and then the two operating fingers are merged, so that the cursor does not move no matter how the wearing finger moves, and then the right click operation is performed. However, for a general user, the operation of lifting two operating fingers is added in the operation, and the use experience is influenced to a certain extent.
In order to solve the problem, the invention provides a ring type mouse capable of prejudging the merging trend of two fingers and a method for controlling a terminal thereof.

The utility model provides a ring formula mouse, is applied to the terminal, the terminal can be desktop computer, notebook computer, smart mobile phone, panel computer, smart television, intelligent wrist-watch, intelligent projecting apparatus, take intelligent glasses of display function etc..
In order to realize the operation of wearing two fingers by one finger, the first contact 5 is positioned in a gap between the wearing finger 1 and the adjacent finger 2 under the working state of the ring-type mouse, when the wearing finger 1 is closed with the adjacent finger 2, the first contact 5 is in a touched state, and when the wearing finger 1 is separated from the adjacent finger 2, the first contact 5 is in a non-touched state. Obviously, two different state signals of a touched state and a non-touched state can be simply and conveniently input into the ring type mouse by the first contact 5, and more operation gestures can be defined under the condition that a single finger wears the ring type mouse on the basis, so that more mouse operation instructions are realized. Fig. 2 shows a schematic diagram of the ring-type mouse in an operating state, in which the first contact 5 is located in a gap between the wearing finger 1 and the adjacent finger 2. Since the skin of the adjacent finger 2 is touched with the first contact 5 when the wearing finger 1 is close to the adjacent finger 2, if the touch state is to be sensed quickly and accurately, the first contact 5 is preferably a capacitive touch switch, and may be other types of touch switches. It should be noted that, according to the present invention, since the inter-finger distance sensor 13 is provided, which can also be used to detect whether the wearing finger 1 and the adjacent finger 2 are in the close state, the inter-finger distance sensor 13 can be used instead of the first contact 5 without considering the response speed, power consumption, and computational cost.
A method for controlling a terminal by a ring-type mouse comprises
Step 1: detecting and determining operation on a ring mouse, including
Detecting the touch of the first contact 5, namely detecting whether the first contact 5 is in a touched state, if so, determining that the operation is a two-finger operation, otherwise, determining that the operation is a one-finger operation;
displacement detection, namely detecting the effective working displacement of the ring-type mouse by adopting the displacement click detection unit; the displacement detection is mainly used for obtaining displacement input data when a cursor moves or drags;
detecting the click operation, namely detecting and judging whether the click operation belongs to one of a single effective click state, a double effective click state and a dragging waiting state by adopting the displacement click detection unit; the click operation detection is mainly used for judging the type of click, corresponds to a mouse operation instruction, and is used for judging whether the click is a single click or a double click or whether the dragging operation is prepared or not;
step 2: defining a preset operation gesture, and performing combination definition or collocation definition on the operation performed on the ring type mouse to form the preset operation gesture; the first contact 5 has two states of touched and non-touched, the clicking has three types of single effective clicking, two effective clicking and dragging waiting states, and whether displacement occurs or not is determined, and the operation states are arranged, combined and defined or matched and defined according to the logic of the traditional mouse operation to obtain a preset operation gesture;
and step 3: establishing a preset corresponding relation between the preset operation gesture and the ring-type mouse operation instruction, and judging the operation instruction corresponding to the current operation on the mouse according to the preset corresponding relation; the establishment of the corresponding relation needs to consider the operation logic of the traditional mouse, so that hands are not tired when the ring-type mouse is used, and more learning cost is not needed when the ring-type mouse is replaced by the traditional mouse;
and 4, step 4: and controlling the operated terminal by applying the operation instruction. The control of the terminal by applying the operation instruction is divided into three conditions: the first condition is that the corresponding from the operation gesture to the operation instruction is completed in the ring type mouse according to the preset corresponding relation, and then the operation instruction is directly sent to the operated terminal to realize the control; and the second situation is that the current operation gesture is directly sent to the operated terminal, and the operated terminal corresponds the received operation gesture into an operation instruction according to the preset corresponding relation, so that control is realized. And in the third situation, the state information of the current ring type mouse, including whether the first contact 5 is touched, whether clicking occurs and the number of times of clicking, displacement data and the time sequence of the state information of the three, is directly sent to the operated terminal, the operated terminal processes the state information to obtain a corresponding operation gesture, and then the operation gesture is corresponding to an operation instruction according to a preset corresponding relation, and finally the control of the terminal is realized. Preferably, the mode for sending the operation instruction or the operation gesture is a wireless transmission mode; preferably, the wireless transmission mode is a common wireless transmission mode such as bluetooth, WiFi, NFC, mobile communication network, and the like.
As shown in fig. 3, 4 and 5, preferably, the displacement click detection unit is an optical positioning sensor 4, and the first contact 5 and the optical positioning sensor 4 are located in such a way that, in the ring-type mouse operating state, the first contact 5 is located in a gap between two operating fingers, and the optical positioning sensor 4 is opened downwards,
the displacement detection method is that whether the distance between the optical positioning sensor 4 and the working surface of the mouse is smaller than or equal to the silent distance set in the optical positioning sensor 4 is detected, if the distance is smaller than or equal to the silent distance, the relative displacement between the optical positioning sensor 4 and the working surface of the mouse detected by the optical positioning sensor 4 is regarded as effective displacement input, otherwise, the relative displacement is regarded as invalid displacement input, and the working surface of the mouse can be the surface of any opaque object with certain roughness; the silent distance is a distance which can reflect a movement instruction after the mouse is lifted, the maximum upper limit of the distance is determined by the performance parameters of the optical positioning sensor 4, and the value of the silent distance can be modified and adjusted by the driving of the optical positioning sensor 4 within the maximum upper limit;
according to the principle that the optical positioning sensor 4 can sense the silent distance, the click operation is detected by detecting the distance change between the optical positioning sensor 4 and the working surface of the mouse,
within a first time threshold range which is less than or equal to a set value, if the distance completely changes from a value which is greater than a first distance threshold value to a value which is less than or equal to the first distance threshold value and then to a value which is greater than the first distance threshold value, judging that one effective click occurs; the distance change of the three stages actually corresponds to a process of lifting, down clicking and lifting the finger, namely corresponds to the operation logic of single clicking;
within a second time threshold range which is smaller than or equal to the set time threshold range, if the distance completely changes from being larger than the first distance threshold to being smaller than or equal to the first distance threshold, then to being larger than the first distance threshold, then to being smaller than or equal to the first distance threshold, and then to being larger than the first distance threshold in five stages, judging that two effective continuous clicks occur; the distance change of the five stages actually corresponds to a process of lifting the finger, clicking downwards, lifting again, then clicking downwards again and lifting again, namely the operation logic corresponding to two continuous clicks;
within a third time threshold range which is smaller than or equal to the set time threshold range, if the distance completely changes from being larger than the first distance threshold to being smaller than or equal to the first distance threshold, then to being larger than the first distance threshold, and then to being smaller than or equal to the first distance threshold, and then the time which is continuously kept smaller than or equal to the first distance threshold exceeds a fourth time threshold, the current operation is judged to be in a dragging waiting state; the distance change process actually corresponds to the operation logic of the finger lifting, downward clicking, lifting again, then downward clicking again, and then staying in the process of preparing dragging, namely continuously clicking twice, and after the last click, the finger does not leave the working surface of the mouse, namely the waiting state before dragging;
the method for detecting the clicking operation by utilizing the distance change between the optical positioning sensor 4 and the mouse working surface has requirements on the use mode of the ring-type mouse, namely the open end of the optical positioning sensor 4 is required to be contacted with the mouse working surface or to be close to the mouse working surface as much as possible when the finger is clicked downwards, if the finger is clicked under the bending state, the ring-type mouse is required to be worn on the finger joint near the fingertip, but if the ring-type mouse is worn on the finger joint close to the palm, the finger 1 is required to be worn by straightening when the finger is clicked, so that the wearing finger 1 is lifted upwards by a certain angle around the joint between the finger 1 and the palm and then is clicked;
the first time threshold to the fourth time threshold can be set according to actual needs, and corresponding time thresholds used in the click operation can be generally judged on the traditional notebook touch pad;
preferably, the first distance threshold is equal to a silent distance set in the optical positioning sensor 4;
because the ring-type mouse is worn on a finger and has a small size, the internal space of the ring-type mouse is very limited, and certain requirements are made on the size and the packaging mode of internal components. Preferably, the model of the optical positioning sensor 4 can be Agilent ADNS-2610 or ADNS-2620 or raw phase PAW3204LU-TJDU or PAW3220LU-TJDU, and the packaging size of the optical positioning sensors is small and can meet the internal space requirement of the ring mouse.
As shown in fig. 4 and 5, preferably, a proximity sensor 11 may be further used to detect a click operation, the proximity sensor 11 is located on the same surface as the open end of the optical pointing sensor 4 and is disposed near the optical pointing sensor 4, when a distance between the surface on which the optical pointing sensor 4 is located and the mouse working surface is greater than a second distance threshold, an output result of the proximity sensor 11 is in a non-proximity state, when the distance is less than or equal to the second distance threshold, an output result of the proximity sensor 11 is in a proximity state, and when the distance is changed from less than or equal to the second distance threshold to greater than the second distance threshold, the output result of the proximity sensor 11 returns to the non-proximity state. The approach of detecting a click operation using the proximity sensor 11 is,
within a first time threshold range which is less than or equal to a set value, if the output result of the proximity sensor 11 completely changes from a non-proximity state to a proximity state and then to a non-proximity state, determining that a valid click occurs;
within a second time threshold range which is less than or equal to the set value, if the output result of the proximity sensor 11 completely changes from a non-proximity state to a proximity state, then to a non-proximity state, then to a proximity state, and then to a non-proximity state, then two effective continuous clicks are determined to occur;
within a third time threshold range which is less than or equal to the set time threshold range, if the output result of the proximity sensor 11 completely changes from a non-proximity state to a proximity state, then to a non-proximity state, then to a proximity state, and then the time for continuously keeping the proximity state exceeds a fourth time threshold, the current operation is judged to be a dragging waiting state;
preferably, the proximity sensor 11 is an infrared distance sensor;
preferably, the proximity sensor 11 is a TOF distance sensor;
preferably, the proximity sensor 11 is a structured light distance sensor;
of course, the size and the internal space of the ring-type mouse are limited, so that no matter which sensor is selected, the model with the small packaging size is selected as far as possible in the selection of the components. Taking an infrared distance sensor as an example, the package size of the TMD2635 infrared distance sensor released by AMS EMIES semiconductor company is only 1 cubic millimeter, which can meet the requirements of a ring type mouse;
the second distance threshold is set according to the performance, characteristics and actual needs of the proximity sensor 11, and preferably, the second distance threshold is equal to the first distance threshold.
Preferably, a distance switch may be further used to implement the click operation detection, the distance switch and the open end of the optical positioning sensor 4 are located on the same surface and are disposed near the optical positioning sensor 4, when the distance between the surface where the optical positioning sensor 4 is located and the mouse working surface is greater than a third distance threshold, the open/close state of the distance switch is maintained in an initial state, when the distance is less than or equal to the third distance threshold, the open/close state of the distance switch is changed, which is called as the open/close state of the changed distance switch being a trigger state, and when the distance is less than or equal to the third distance threshold and is greater than the third distance threshold, the open/close state of the distance switch returns from the trigger state to the initial state. The method for detecting the click operation using the distance switch is,
within a first time threshold range which is less than or equal to a set value, if the on-off state of the distance switch completely changes from an initial state, a trigger state and the initial state, judging that one effective click occurs;
within a second time threshold range which is less than or equal to the setting range, if the on-off state of the distance switch completely changes from the initial state, the triggering state, the initial state, the triggering state and the initial state, two effective continuous clicks are determined to occur;
within the range of less than or equal to the set third time threshold, if the on-off state of the distance switch completely changes from the initial state, the trigger state, the initial state and the trigger state, and the time for continuously keeping the trigger state exceeds the fourth time threshold, the current operation is judged to be the dragging waiting state;
preferably, the distance switch is a spring-type reboundable switch, the spring-type reboundable switch is triggered when the distance switch is pressed to a certain degree and is changed into a triggered state from an initial state, and the spring-type reboundable switch rebounds when the distance switch is lifted to a certain degree, the triggered state is ended, and the distance switch returns to the initial state from the triggered state.
