Description
Technical Field
The invention relates to the field of mice, in particular to a finger ring type mouse capable of prejudging a two-finger merging trend and a method for controlling a terminal by the same.
Background
Common terminals include desktop computers, notebook computers, smart phones, tablet computers, smart televisions, smart watches, smart projectors, smart glasses with display functions, and the like. With the development of portable terminals, people have also put higher and higher demands on the portability of peripheral devices of the operation terminals, wherein the most common peripheral devices are a keyboard and a mouse, and the keyboard is the most portable at present, namely a film-rolled keyboard and a projection keyboard, but as for the mouse, although a wide range of manufacturers are pushing out a light and thin mouse, the mouse is still not portable enough. Particularly, after the 5G era, the popularization of the cloud computer gradually enables the mobile phone and the intelligent glasses to be used as the computer, but if the mobile phone or the intelligent glasses are used for mobile office, the mobile office is very popular with a traditional mouse, so that a more miniature and portable peripheral capable of replacing the traditional mouse is urgently needed.
In view of the above problems, the present inventors have previously filed a patent name of "a finger ring type mouse", an application number of "2019109515241", and two patent applications of "a finger ring type mouse control terminal" and an application number of "2019109515237", which propose a finger ring type mouse and a method for controlling a terminal thereof, wherein all functions of a conventional mouse are integrated into a compact finger ring, and after the finger ring type mouse is put on, all operations of the conventional mouse including clicking, double clicking, right clicking, cursor movement, dragging, scroll wheel scrolling, button pressing in the mouse and button dragging in the mouse can be completed by two fingers.
In the product development test process of the finger ring type mouse, the inventor finds a small problem, and the problem is described as follows: if the gesture operation of moving the wearing finger along the working surface of the mouse is defined as cursor movement in a state that the wearing finger is separated from the adjacent finger; defining a gesture of clicking the two fingers together for a single time as right clicking under the state that the wearing finger and the adjacent finger are combined; in this case, when the fixed point right click operation is performed after the operation cursor is moved to a certain determined position, the state between the wearing finger and the adjacent finger needs to be converted from the separated state to the combined state, and in this conversion process, it is difficult to move only the adjacent finger and keep the wearing finger stationary due to the limitation of the operation flexibility of the fingers of the ordinary person, the wearing finger is inevitably moved, 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 order to realize the right click at the fixed point, only after the operation cursor moves to a certain determined position, the two operation fingers are slightly lifted to enable the distance between the optical positioning sensor and the working surface of the mouse to exceed the silence distance, and then the combination is carried out, so that the cursor does not move no matter how the wearing finger is moved, and then the right click operation is carried out. However, for the common user, the operation of lifting two operation fingers is increased, which has a certain influence on the use experience.
In order to solve the problem, the invention provides a finger ring type mouse capable of prejudging the merging trend of two fingers and a method for controlling a terminal thereof.

As shown in fig. 1 to 5, a specific implementation manner of a method for predicting a finger ring type mouse control terminal with a two-finger merging trend according to the present invention is as follows:
the method for the finger ring type mouse control terminal capable of prejudging the two-finger merging trend is based on the finger ring type mouse capable of prejudging the two-finger merging trend, and comprises the following steps: when the inter-finger distance sensor 13 detects that the decrease of the distance between the wearing finger 1 and the adjacent finger 2 within the fifth time threshold is larger than or equal to the fourth distance threshold, it is determined that the wearing finger 1 and the adjacent finger 2 have a merging trend, and at the moment, the displacement input of the optical positioning sensor 4 is shielded, and the cursor on the controlled terminal is no longer moved along with the movement of the optical positioning sensor 4 relative to the working surface of the mouse.

In view of the improvement of the invention, namely, a finger ring type mouse, application number of 2019109515241 and a method for controlling a terminal by using the finger ring type mouse, and application number of 2019109515237, the invention is better understood, and the contents of the two inventions are supplemented in detail.
The finger ring type mouse is applied to a terminal, and the terminal can be a desktop computer, a notebook computer, a smart phone, a tablet computer, a smart television, a smart watch, a smart projector, smart glasses with display functions and the like.
In order to realize the operation of wearing two fingers by one finger, the first contact 5 is positioned in a crack between the wearing finger 1 and the adjacent finger 2 in 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 an untouched state. Obviously, two different state signals of a touched state and a non-touched state can be simply input to the ring type mouse by the first contact 5, and more operation gestures can be defined under the condition of wearing the ring type mouse by a single finger based on the two different state signals, so that more mouse operation instructions are realized. Fig. 2 shows a schematic diagram of the operating state of the ring mouse, in which the first contact 5 is located in the nip 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 in the state that the finger 1 is put together with the adjacent finger 2, if the touch state is quickly and accurately sensed, it is preferable that the first contact 5 is a capacitive touch switch, or may be another type of touch switch. It is 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 a closed state, the inter-finger distance sensor 13 can be used instead of the first contact point 5 without taking into consideration the response speed, power consumption and calculation effort.
A method for controlling a terminal by a ring mouse includes
Step 1: detecting and determining operations performed on a ring mouse, including
The first contact 5 is in touch detection, namely whether the first contact 5 is in a touched state is detected, if the first contact is in the touched state, the two-finger operation is judged at the moment, otherwise, the single-finger operation is judged at the moment;
detecting displacement, namely detecting effective working displacement of the ring 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;
click operation detection, namely detecting and judging which of single effective click, two effective clicks and dragging waiting states the generated click operation belongs to by adopting the displacement click detection unit; the click operation detection is mainly used for judging the type of clicking and corresponds to a mouse operation instruction, and whether clicking or double clicking is needed or whether dragging operation is ready to be carried out is judged;
step 2: defining a preset operation gesture, and carrying out combination definition or collocation definition on the operation of 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, twice effective clicking and dragging waiting states, and in addition, whether displacement occurs or not, the operating states are defined by permutation and combination or collocation according to the logic of the traditional mouse operation, so as to obtain a preset operation gesture;
step 3: establishing a preset corresponding relation between the preset operation gesture and the ring-type mouse operation instruction, and judging an 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;
step 4: and controlling the operated terminal by applying the operation instruction. The control of the terminal is realized by applying the operation instruction in three cases: the first case is that according to the preset corresponding relation, the corresponding from the operation gesture to the operation instruction is completed in the ring-shaped mouse, and then the operation instruction is directly sent to the operated terminal to realize control; in the second case, the current operation gesture is directly sent to the operated terminal, and the operated terminal corresponds the received operation gesture to an operation instruction according to a preset corresponding relation to realize control. And in the third case, the state information of the current ring mouse, including whether the first contact 5 is touched, whether the clicking and the clicking times and displacement data occur, 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, 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, etc.
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 positioned in a relationship that, in the working state of the ring-type mouse, the first contact 5 is located in a gap between two operation fingers, and at the moment, the optical positioning sensor 4 is opened downwards,
the displacement detection method is to detect whether the distance between the optical positioning sensor 4 and the working surface of the mouse is smaller than or equal to the silence distance set in the optical positioning sensor 4, if the distance is smaller than or equal to the silence distance, the relative displacement between the optical positioning sensor 4 and the working surface of the mouse is regarded as effective displacement input, otherwise, the relative displacement is regarded as ineffective displacement input, and the working surface of the mouse can be any opaque surface with certain roughness; the silence distance is a distance which can also 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 silence 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 silence distance, the clicking operation is detected by detecting the change of the distance between the optical positioning sensor 4 and the working surface of the mouse,
if the distance is completely changed from being greater than a first distance threshold to being less than or equal to the first distance threshold and then to being greater than the first distance threshold within a range of the first time threshold, judging that one effective click occurs; the distance change of the three stages actually corresponds to one process of finger lifting, clicking downwards and lifting again, namely corresponds to the operation logic of single clicking;
if the distance is completely changed from being greater than the first distance threshold to being less than or equal to the first distance threshold, to being greater than the first distance threshold, to being less than or equal to the first distance threshold, and to being greater than five stages of change of the first distance threshold, then determining that two effective continuous clicks are generated; the distance change of the five stages actually corresponds to one process of finger lifting, clicking downwards, lifting again, clicking downwards again and lifting again, namely, corresponds to the operation logic of two continuous clicks;
if the distance is completely changed from the first distance threshold value to the first distance threshold value, and to the first distance threshold value, in a third time threshold value range which is smaller than or equal to the set third time threshold value, and then the time of continuously keeping the first distance threshold value smaller than or equal to the first distance threshold value exceeds a fourth time threshold value, judging that the current operation is in a dragging waiting state; the distance change process actually corresponds to the process of lifting, clicking downwards, re-lifting, clicking downwards again, and then stopping for preparing the dragging, namely clicking twice continuously but the finger does not leave the working surface of the mouse after the last click, namely, the operation logic of waiting state before dragging;
in the method for detecting the clicking operation by using the distance change between the optical positioning sensor 4 and the working surface of the mouse, the use mode of the ring-shaped mouse is required, namely, when clicking downwards, the opening end of the optical positioning sensor 4 is required to be in contact with the working surface of the mouse or to be as close to the working surface of the mouse as possible, if clicking operation is performed in a finger bending state, the ring-shaped mouse is required to be worn on a finger joint near a fingertip, but if the ring-shaped mouse is worn on the finger joint close to a palm, the wearing finger 1 is required to be straightened when clicking, so that the wearing finger 1 is lifted upwards by a certain angle around the joint of the wearing finger 1 and the palm and then clicking is performed;
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 judged on the traditional notebook touch pad;
preferably, the first distance threshold is equal to a silence distance set in the optical positioning sensor 4;
because the ring mouse is worn on the finger, the size is small, the internal space is very limited, and certain requirements are imposed on the size and the packaging mode of the internal components. Preferably, the optical positioning sensor 4 may be Agilent ADNS-2610, ADNS-2620, or primary PAW3204LU-TJDU, or PAW3220LU-TJDU, which have smaller package size and can meet the internal space requirement of the ring mouse.
As shown in fig. 4 and 5, it is preferable that the click detection is performed by using a proximity sensor 11, where the proximity sensor 11 is located on the same surface as the opening end of the optical positioning sensor 4 and is disposed near the optical positioning sensor 4, and when the distance between the surface of the optical positioning sensor 4 and the working surface of the mouse is greater than a second distance threshold, the output result of the proximity sensor 11 is in an unoccupied state, and when the distance is less than or equal to the second distance threshold, the output result of the proximity sensor 11 is in an already-approximated state, and when the distance is changed from less than or equal to the second distance threshold to be greater than the second distance threshold, the output result of the proximity sensor 11 is changed back to an unoccupied state. The method of detecting a click operation using the proximity sensor 11 is,
if the output result of the proximity sensor 11 is completely changed from the non-approaching state to the approaching state and then to the non-approaching state within the set first time threshold range, determining that a valid click is generated;
if the output result of the proximity sensor 11 is completely changed from the non-proximity state to the proximity state, to the non-proximity state, to the proximity state, and to the non-proximity state within the set second time threshold range, determining that two effective continuous clicks occur;
if the output result of the proximity sensor 11 is completely changed from the non-approaching state to the approaching state, to the non-approaching state, to the approaching state, and then to the approaching state within a set third time threshold range, and the time for continuously maintaining the approaching state exceeds a fourth time threshold, determining that the current operation is a drag 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, since the size and the internal space of the ring mouse are limited, a model with a small package size is selected as much as possible for the type of the component no matter which sensor is selected. Taking an infrared distance sensor as an example, the packaging size of the TMD2635 infrared distance sensor pushed by AMS Ai Maisi semiconductor company is only 1 cubic millimeter, so that the requirements of the ring-type mouse can be met;
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, the click detection may be implemented by using a distance switch, where 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, and when the distance between the surface where the optical positioning sensor 4 is located and the working surface of the mouse is greater than a third distance threshold, the open-close state of the distance switch is maintained in an initial state, and when the distance is less than or equal to the third distance threshold, the open-close state of the distance switch is changed, and the open-close state of the distance switch after the change is called as a trigger state, and when the distance is changed from less than or equal to the third distance threshold to 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 of detecting a click operation using a distance switch is,
if the opening and closing state of the distance switch completely changes from the initial state to the trigger state and then to the initial state within a range smaller than or equal to a set first time threshold value, judging that one effective click occurs;
if the opening and closing state of the distance switch completely changes from the initial state to the trigger state, then to the initial state, then to the trigger state and then to the initial state within a second time threshold range which is smaller than or equal to the set value, judging that two effective continuous clicks occur;
if the opening and closing state of the distance switch completely changes from the initial state to the trigger state, then to the initial state and then to the trigger state within a third time threshold range which is smaller than or equal to the set value, and the time for continuously keeping the trigger state exceeds a fourth time threshold, judging that the current operation is in a dragging waiting state;
preferably, the distance switch is a spring type rebounding switch, the spring type rebounding switch is triggered when the distance switch is pressed down to a certain extent, the spring type rebounding switch is changed into a trigger state from an initial state, and when the distance switch is lifted up to a certain extent, the spring type rebounding switch rebounds, the trigger state is ended, and the distance switch returns to the initial state from the trigger state. The third distance threshold is determined by the mechanical structure and the design size of the distance switch, and preferably, the third distance threshold, the second distance threshold and the first distance threshold are equal.
Preferably, the displacement click detection unit is an acceleration sensor 6, the acceleration sensor 6 is positioned in the ring mouse,
the displacement detection method comprises the steps of carrying out secondary integration on acceleration signals acquired by the acceleration sensor 6 to obtain displacement distance information and displacement direction information;
the clicking operation detection method includes that the acceleration sensor 6 detects the acceleration change of the ring mouse, and if the acceleration change is detected and then the second acceleration change is detected within a range smaller than or equal to a set first time threshold value, the effective clicking is judged to occur; in a second time threshold range which is smaller than or equal to the set value, if four features of the first acceleration change feature, the second acceleration change feature, the first acceleration change feature and the second acceleration change feature are detected in sequence, judging that two effective continuous clicks occur; and in a third time threshold range which is smaller than or equal to the set value, if the three characteristics of the first acceleration change characteristic, the second acceleration change characteristic and the first acceleration change characteristic are detected continuously in sequence, and after that, the waiting time exceeds the fourth time threshold value, the second acceleration change characteristic is not detected yet, and the current operation is judged to be in a dragging waiting state. The first acceleration change characteristic is that a finger collides with the working surface of the mouse when clicking to suddenly reduce the speed, a very obvious acceleration abrupt change characteristic exists at the moment, and the acceleration abrupt change characteristic is defined as the first acceleration change characteristic; the second acceleration change feature is an acceleration change when the finger lifts up after clicking occurs, and is defined as a second acceleration abrupt change feature. If the click operation is detected by using the acceleration change feature, a large amount of acceleration change waveform data generated during the click operation needs to be machine-learned, so that the accuracy of detection and recognition can be improved.

As shown in fig. 1 and 2, the preset operation gestures preferably include
First gesture: wearing the finger 1 to click for a single time under the state that the wearing finger 1 is separated from the adjacent finger 2;
the second gesture: wearing the finger 1 to click twice continuously in a state that the wearing finger 1 is separated from the adjacent finger 2;
third gesture: when the wearing finger 1 and the adjacent finger 2 are combined, the two fingers click together for a single time;
fourth gesture: the wearing finger 1 moves along the working surface of the mouse in a state that the wearing finger 1 is separated from the adjacent finger 2;
fifth gesture: when the wearing finger 1 is separated from the adjacent finger 2, the wearing finger 1 does not leave the working surface of the mouse after being clicked twice, namely, is in a dragging waiting state, and then the wearing finger 1 moves along the working surface of the mouse;
sixth gesture: the wearing finger 1 and the adjacent finger 2 move along the working surface of the mouse together in a combined state;
seventh gesture: when the wearing finger 1 and the adjacent finger 2 are combined, the two fingers perform two continuous clicks together;
eighth gesture: when the finger 1 is worn and the adjacent finger 2 is combined, the two fingers do not leave the working surface of the mouse after being clicked twice continuously, namely, the two fingers are in a dragging waiting state, and then the two fingers are moved along the working surface of the mouse;
ninth gesture: in a state that the wearing finger 1 is separated from the adjacent finger 2, the wearing finger 1 does not leave the working surface of the mouse after being clicked for a single time, and then the wearing finger 1 moves along the working surface of the mouse;
tenth gesture: when the wearing finger 1 and the adjacent finger 2 are combined, the two fingers do not leave the working surface of the mouse after clicking for a single time, and then the two fingers are moved along the working surface of the mouse;
for the fourth gesture, the fifth gesture, the sixth gesture, the eighth gesture, the ninth gesture and the tenth gesture, because there is a moving process, a gesture instruction for ending movement needs to be given, and preferably, the gesture instruction for ending movement includes:
first end move instruction: in the moving process, when the finger leaves the working surface of the mouse, the gesture operation is finished;
second end move instruction: in the moving process, when the separation or combination state between the wearing finger 1 and the adjacent finger 2 is changed, the gesture operation is finished; that is, the state between the wearing finger 1 and the adjacent finger 2 ends the current gesture operation regardless of whether it is changed from split to merge or from merge to split.
According to the operation logic of the traditional mouse, there are eight main conventional operation instructions, namely single click, double click, right click, cursor movement, dragging, roller scrolling, key pressing in the mouse and key dragging in the mouse. According to the operation instructions of the conventional mouse, the operation instructions also comprise single click, double click, right click, cursor movement, dragging, roller scrolling, key pressing in the mouse and key dragging in the mouse.
As shown in fig. 1 and 2, preferably, the operation manners of the first gesture to the tenth gesture are:
the wearing mode of the finger ring type mouse is the working state shown in figure 2;
when the mouse moves, the palm stretches and moves against the working surface of the mouse;
during clicking, the joints of the fingers 1 and the adjacent fingers 2 are not bent, and the fingers participating in the operation only lift up a certain angle around the joint of the fingers and the palm and then click.
If the optical positioning sensor 4 is adopted to realize displacement detection, the above operation mode has the advantages that the palm postures of all operations are basically unchanged, the bending or straightening states of the fingers and the palm do not need to be changed greatly and frequently, even the clicking operation is finished by only slightly lifting the fingers to a certain angle and then clicking downwards, so that the complexity and difficulty of the operation are reduced, and meanwhile, the hands are not tired.
As shown in fig. 1 and fig. 2, the conventional operation instructions of the conventional mouse are eight, and in order to avoid two-by-two conflicts between different operation instructions, preferably, the preset corresponding relationship is as follows:
the operation instruction corresponding to the first gesture is a click; as shown in a in fig. 1;
the operation instruction corresponding to the second gesture is double-click; as shown in B in fig. 1;
the operation instruction corresponding to the third gesture is right click; as shown at C in fig. 1;
the operation instruction corresponding to the fourth gesture is cursor movement; as shown at D in fig. 1;
the operation instruction corresponding to the fifth gesture is dragging; as shown by E in fig. 1;
the operation instruction corresponding to the sixth gesture is roller scrolling; as shown by F in fig. 1;
the operation instruction corresponding to the seventh gesture is a key press in the mouse; as shown at G in fig. 1;
and the operation instruction corresponding to the eighth gesture is dragging of a middle button of the mouse. As indicated by H in fig. 1;
under the preset corresponding relation, the main problem solved by the invention is that the cursor can be greatly moved and far away from the current cursor position when the cursor is clicked right;
according to the preset corresponding relation, the two gestures of the ninth gesture and the tenth gesture are not applied, so that the ninth gesture and the tenth gesture can be used as standby gestures or redundant gestures, and operation instructions and functions corresponding to the ninth gesture and the tenth gesture can be customized according to actual needs in actual application;
preferably, in the sixth gesture, the instruction corresponding to forward movement is consistent with the instruction of the conventional mouse for forward scrolling the wheel, and the instruction corresponding to backward movement is consistent with the instruction of the conventional mouse for backward scrolling the wheel. Of course, the correspondence between the two instructions may be reversed, and the use experience is not substantially affected after the exchange.
Finally, it should be noted that, the above description of the directions in the finger ring type mouse wear and the operation gestures uses the mouse working surface as a reference frame, and if the mouse working surface is not horizontal, the corresponding direction description should also deflect with the deflection of the mouse working surface relative to the horizontal direction.
