In an embodiment of the present embodiment, determines and be expected according to the depth of the display stereo content and operation instruction Depth value the step of include：

Depth adjusted value is determined according to operation instruction；

In present embodiment, the first, second predetermined trend is given tacit consent to or is set by the user.

Such as when the operation instruction is single point gesture, the first predetermined trend can be input body and electronic equipment The distance between display screen become close, the second predetermined trend can be between input body and the display screen of electronic equipment Distance become remote.

For another example when the operation instruction is that single-point presses, the first predetermined trend can be that pressure becomes larger.

For another example when the operation instruction be single point movement when, the first predetermined trend can be input point position to Right or upward or upper movement to the right；The second predetermined trend can be the position of input point to the left downwards or to left down It is mobile.

For another example when the operation instruction is 2 points of slidings, the first predetermined trend can be between two input points Distance become larger；The second predetermined trend can be that the distance between two input points become smaller.

For another example when the operation instruction is 2 points of rotations, the first predetermined trend can be that two input points are constituted Vector rotate clockwise, the second predetermined trend can be the vector rotation counterclockwise that two input points are constituted.

When the operation instruction includes a variety of, the first, second predetermined trend can include accordingly a variety of, for example grasp It includes that single-point presses and single point gesture to make instruction, then the first predetermined trend includes that pressure becomes larger and input body and electronic equipment Show that the distance between screen becomes close.

When the operation instruction includes a variety of, the described first, second predetermined trend can also be limited to one kind, such as Operation instruction includes single point movement and two point sliding, can the first predetermined trend be limited to any one direction or specific direction Single point movement, the second predetermined trend is limited to the distance between two input points and changes the one kind of/becoming larger/in becoming smaller.

In present embodiment, the depth adjusted value is the product of adjusting ratio and adjustable range；

The adjustable range can be preset or determine according to the user's choice, can also be according to the electronic equipment sheet The display performance of body determines；It is anti-fake can also to obtain the adjusting in different ways according to variation tendency, such as this implementation It is arranged in a kind of scheme of mode：

When the operation instruction matches the first predetermined trend, the adjustable range is the maximum of the display stereo content The difference of depth value and initial depth value；When the operation instruction matches the second predetermined trend, the adjustable range is described aobvious Show the difference of the initial depth value of stereo content and the minimum depth value of the display stereo content；The initial depth value is to receive When the depth adjustment trigger signal, the depth of the detected display stereo content.

In a kind of alternative of present embodiment, the adjusting ratio can be, but not limited to input the Parameters variation of body The ratio between value and scheduled maximum amplitude value.

The parameter of the input body can be, but not limited to：The input body and the electronic equipment when single point gesture Pressure, single point movement when the distance between screen, single-point pressing to electronic equipment application（The input body is set in electronics Standby input area forms an input point and movement）When position of the input point in input area, 2 points of slidings（The input body Two input points and close to each other or separate are formed in electronic equipment input area）When the distance between two input points, 2 points Rotation（The input body forms two input points, and the Vector rotation that two input points are constituted in electronic equipment input area） The vector etc. that two input points are constituted in input area.The input area can be, but not limited to include electronic equipment touch Screen, Trackpad, the input area for projecting formation in the plane or the region etc. of other detectable input body actions.It can be by touching Parameter described in any of detection hardware such as screen/touch tablet, range sensor, pressure sensor or arbitrary combine detection is touched to become Change value；The detection hardware had both included detection hardware built-in in the electronic equipment, also included with the electronic equipment with nothing Line or the detection hardware of wired mode connection.

Such as when the operation instruction is single point movement, the adjusting ratio is displacement distance and scheduled amplitude peak The ratio between value；Between position when the displacement distance is input point current location and receives the depth adjustment trigger signal away from From.

For another example when the operation instruction is 2 points of slidings, the adjusting ratio is the variable quantity of two input point distances The ratio between with scheduled maximum amplitude value；The variable quantity of described two input point distances be two input point current times distance with The absolute value of the difference of distance when receiving the depth adjustment trigger signal.

For another example when the operation instruction is 2 points of rotations, the adjusting ratio isWith it is scheduled most Substantially the ratio between angle value, V₀It is the vector that two input points are constituted when receiving the depth adjustment trigger signal, V_tIt is current time institute State the vector of two input points composition.

For another example when the operation instruction be single-point press when, the adjusting ratio be pressure value variable quantity with it is scheduled The ratio between maximum amplitude value；The pressure when variable quantity of the pressure is vertex pressure value and receives the depth adjustment trigger signal Since the absolute value of the difference of value, the vertex pressure value are receiving the depth adjustment trigger signal, until current time Maximum pressure value.

For another example when the operation instruction is single point gesture, the adjusting ratio is input body and the electronic equipment The ratio between the variable quantity of distance and scheduled maximum amplitude value between display screen；The variable quantity of the distance is described in current time The distance between the display screen for inputting body and the electronic equipment, with input when receiving the depth adjustment trigger signal The absolute value of the difference of body and the distance between the display screen of the electronic equipment.

The maximum amplitude value can be preset fixed value or determine according to the user's choice, can also be according to the behaviour The type for making to indicate accordingly selects the corresponding parameter of electronic equipment or display area as the maximum amplitude value, can also basis Different variation tendencies selects different maximum amplitude value.

For example when the operation instruction is single point movement or 2 points of slidings, the maximum amplitude value can be electronic equipment Display screen or the display area height or width, or preset length.When the operation instruction is When 2 points of slidings, it can also be arranged to：When variation tendency is that the distance between two input points become small, to receive the depth The distance between two input points are used as the maximum amplitude value when adjusting trigger signal；When variation tendency is two input points Between distance when becoming larger, to receive the maximum distance being likely to be breached between two input points as the maximum amplitude value.

For another example when the operation instruction is 2 points of rotations, maximum amplitude value can be certain preset angle or can The maximum rotation angle that can occur.

For another example when the operation instruction is single point gesture, maximum amplitude value can be preset distance or can examine The maximum range value measured.

For another example when the operation instruction is that single-point presses, maximum amplitude value can be the maximum pressure being likely to occur Value.

In the present embodiment, the maximum amplitude value can be definite value, can also change according to fineness is adjusted；Different It adjusts fineness and corresponds to different maximum amplitude value；The adjusting fineness is higher, and corresponding maximum amplitude value is bigger.

Since the performance accuracy of human hand or finger is limited, it is difficult to accurate perception amplitude of variation；Therefore, when need to depth into When row fine tuning, higher adjusting fineness may be selected, since the corresponding maximum amplitude value of higher adjusting fineness is larger, For same parameter variation value, obtained adjusting ratio is smaller, and depth adjusted value is also just corresponding smaller.

For example corresponding maximum amplitude value is 10 centimetres when high adjustment fineness, when operation instruction is single point movement and movement When distance is 1 centimetre, the ratio that adjusts is 0.1, and depth adjusted value is 1/10th of adjustable range；And when top adjustment fineness pair The maximum amplitude value answered is 50 centimetres, and when operation instruction is single point movement and displacement distance is 1 centimetre, adjusting ratio is 0.02, depth adjusted value is 1st/50th of adjustable range；As it can be seen that even if the case where being used as input body using hand or finger Under, it can similarly carry out point-device depth adjustment.

It, can be with the coarse adjustment side of set depth other than allowing user to select to adjust the mode of fineness in the present embodiment Formula and fine-tuning mode；Depth adjusted value is just determined according to the parameter variation value under coarse adjustment mode；Under fine-tuning mode, depth adjustment Value is a preset, smaller definite value, does not change with parameter variation value and changes.When selecting fine-tuning mode, the depth The size of adjusted value is preset value.

Such as being slided on the touch screen of electronic equipment with finger, when selecting fine-tuning mode, finger sliding Direction determines that depth is to increase or reduce, but no matter the distance of finger sliding is how many, and depth adjusted value is all described pre- If value；The preset value can be for default value or by user setting；When the preset value is smaller, even if using hand or finger as defeated Enter body, subtle depth adjustment can also be carried out.

Embodiment two, a kind of device adjusting depth of three-dimensional content, including：

In the present embodiment, the display device can also include a UI（User interface）Module：It can show or close solid Content depth value adjusts prompt message.

In an embodiment of the present embodiment, depth and operation of the processing module according to the display stereo content Instruction determines that expected depth value can refer to specifically：

In present embodiment, the processing module determines depth adjusted value specifically according to operation instruction to refer to：

In a kind of alternative of present embodiment, the processing module can be also used for when operation instruction matching the When one predetermined trend, by the adjustable range be set as the display stereo content maximum depth value and initial depth value it Difference；When the operation instruction matches the second predetermined trend, it sets the adjustable range to the first of the display stereo content The difference of the minimum depth value of beginning depth value and the display stereo content；The initial depth value is to receive the depth adjustment to touch When signalling, the depth of the detected display stereo content.

In present embodiment, the processing module can be also used for when the operation instruction is single point movement, will be described It is the ratio between displacement distance and scheduled maximum amplitude value to adjust ratio setting；The displacement distance is input point current location and receipts The distance between position when to the depth adjustment trigger signal.

Embodiment three, a kind of adjusting method of depth of three-dimensional content value, the embodiment adjust stereo content by touch screen Depth value；Coordinate involved by the embodiment is planar x-y coordinate system, such as on touch screen 11 as shown in Figure 2 a, x-axis It is the width direction of the touch screen 11, y-axis is the length direction of the touch screen 12；When touch screen is aobvious according to mode shown in Fig. 2 b Show and in use, x-axis is the length direction of the touch screen 11, y-axis is the width direction of the touch screen 12.In Fig. 2 a and Fig. 2 b institutes Show in situation, is for horizontal sliding when moving along the x-axis, is vertical sliding when being slided along y-axis.

In the present embodiment and following embodiment, the meaning expressed by each letter is as follows：

Expected depth value：Z_t；

Initial depth value：Z₀；

Adjusting ratio Mar；The product of Mar and adjustable range i.e. during adjusting three-dimensional depth value, stereo content Depth adjusted value；

Maximum adjustable-depth：Z_Max（Constant）；

Minimum adjustable-depth：Z_Min（Constant）.

In an embodiment of the present embodiment, when the input gesture detected in display area is single-touch（It can be with It is singly to refer to, can also be the more fingers gathered on one point, can also be the input point that other input bodies are formed）When, it is considered as receipts The depth adjustment trigger signal is arrived.The operation instruction is single point movement, and the displacement distance of input point is：

In above formula, coordinate points P_1-0(x_1-0,y_1-0) represent the touch point coordinates of initial time, coordinate points P_1-t(x_1-t,y_1-t) Represent the touch point coordinates at current time.Sliding distance when the input gesture of user is slip gesture is expressed as sliding amplitude, ao L, using Δ l as the size of parameter variation value.

When the operation instruction is horizontal slip gesture, (y_1-t-y_1-0) value can ignore, then Δ l can abbreviation such as Under：

Δl=|x_1-t-x_1-0| （1-1）

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value WndWidth uses the width value of current stereo content display window.It is assumed that primary During adjusting depth of three-dimensional content value, the width value of current stereo content display window is constant.From the above equation, we can see that working as institute When stating the horizontal width value for sliding amplitude, ao l no more than current stereo content display window of operation instruction, ratio is adjusted For ratio between two：When the horizontal sliding amplitude, ao l of the operation instruction is more than current stereo content display window Width value when, it is maximum to adjust ratio, value 1.Understand that the value of Mar meets：0≤Mar≤1.

It is slided to the right it is assumed that the first predetermined trend is level, the second predetermined trend is that level is slided to the left（Vice versa）, Then expected depth value, institute are worth to plus depth adjustment when the operation instruction is horizontal sliding to the right with initial depth value It is to subtract depth adjustment with initial depth value when level is slided to the left to be worth to expected depth value to state operation instruction.

When the operation instruction is that level is slided to the right, because initial depth value is Z₀, depth of three-dimensional content value maximum It can be adjusted to Z_Max, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,_Max-Z₀).It is expected that depth value can indicate For：

Z_t=Z₀+Mar×(Z_Max-Z₀) （1-3）

Because the value range of the ratio of adjusting Mar is 0~1, it is known that Z_tValue meet：Z₀≤Z_t≤Z_Max。

When the operation instruction is that level is slided to the left, because initial depth value is Z₀, depth of three-dimensional content value minimum It can be adjusted to Z_Min, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,₀-Z_Min).It is expected that depth value can indicate For：

Z_t=Z₀-Mar×(Z₀-Z_Min) （1-4）

Because the value range of the ratio of adjusting Mar is 0~1, it is known that Z_tValue meet：Z_Min≤Z_t≤Z₀。

To sum up, it is contemplated that depth value Z_tExpression formula it is as follows：

When the operation instruction is vertical sliding gesture, (x_1-t-x_1-0) value can ignore, then Δ l can abbreviation such as Under：

Δl=|y_1-t-y_1-0| （2-1）

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value Wndlength uses the height value of current stereo content display window.It is assumed that primary During adjusting depth of three-dimensional content value, the length value of current stereo content display window is constant.From the above equation, we can see that working as institute State operation instruction vertical sliding amplitude, ao l be not more than current stereo content display window height value when, adjust ratio For ratio between two：When the vertical sliding amplitude, ao l of the operation instruction is more than current stereo content display window When the height value of mouth, ratio maximum, value 1 are adjusted.Understand that the value of Mar meets：0≤Mar≤1.

It is assumed that the first predetermined trend is to slide straight up, the second predetermined trend is to slide straight down（Vice versa）, It then is worth to expected depth value plus depth adjustment with initial depth value when the operation instruction is to slide straight up, when The operation instruction is to subtract depth adjustment with initial depth value when sliding straight down to be worth to expected depth value.

When the operation instruction is to slide straight up, because initial depth value is Z₀, depth of three-dimensional content value maximum It can be adjusted to Z_Max, so it is Z that depth of three-dimensional content, which is worth actual adjustable range,_Max-Z₀.It is expected that depth value can indicate For：

Z_t=Z₀+Mar×(Z_Max-Z₀) （2-3）

When the operation instruction is to slide straight down, because initial depth value is Z₀, depth of three-dimensional content value minimum It can be adjusted to Z_Min, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,₀-Z_Min).It is expected that depth value can indicate For：

Z_t=Z₀-Mar×(Z₀-Z_Min) （2-4）

In the another embodiment of the present embodiment, when the input gesture detected in display area be two touches and away from When from variation, it is considered as and has received the depth adjustment trigger signal.The operation instruction is 2 points of slidings, two input points（I.e. Touch point）Distance change amount：

In above formula, coordinate points P_1-0(x_1-0,y_1-0) represent one of initial time touch point coordinates, coordinate points P_2-0(x_2-0, y_2-0) represent initial time another touch point coordinates, coordinate points P_1-t(x_1-t,y_1-t) represent the touch point at current time Coordinate, coordinate points P_2-t(x_2-t,y_2-t) represent current time another touch point coordinates.Line between two touch point of current time Line segment between two touch point of segment distance and initial moment apart from size delta l' of the absolute value of the difference as the parameter variation value.

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value WndWidth uses the width value of current stereo content display window.It is assumed that primary During adjusting depth of three-dimensional content value, the width value of current stereo content display window is constant.From the above equation, we can see that working as institute State the distance change amount Δ l' of two input points of operation instruction no more than current stereo content display window width value when It waits, adjusting ratio is ratio between two：When the distance change amount Δ l' of two input points of the operation instruction is big When the width value of current stereo content display window, ratio maximum, value 1 are adjusted.Understand that the value of Mar meets：0 ≤Mar≤1。

It is assumed that the distance that the first predetermined trend is two input points becomes larger, the second predetermined trend is the distance of two input points Become smaller（Vice versa）, then when the distance of two input points of the operation instruction becomes larger, depth tune is added with initial depth value Section is worth to expected depth value；The distance of two input points of the operation instruction becomes hour, and depth is subtracted with initial depth value Degree adjusts and is worth to expected depth value.

When the distance of two input points of the operation instruction becomes larger（For example the gesture of the operation instruction is amplification hand Gesture）When, because initial depth value is Z₀, depth of three-dimensional content value maximum can be adjusted to Z_Max, so depth of three-dimensional content value is practical Adjustable range be (Z_Max-Z₀).It is expected that depth value be represented by：Z_t=Z₀+Mar×(Z_Max-Z₀) （3-3）

When the distance of two input points of the operation instruction becomes smaller（For example it is to reduce gesture that user, which inputs gesture,）When, because It is Z for initial depth value₀, depth of three-dimensional content value minimum can be adjusted to Z_Min, so depth of three-dimensional content is worth actual adjusting model It encloses for (Z₀-Z_Min).It is expected that depth value be represented by：

Z_t=Z₀-Mar×(Z₀-Z_Min) （3-4）

In an embodiment of the present embodiment, when the input gesture detected in display area is two touches and rotation Gesture when, be considered as and have received the depth adjustment trigger signal.The operation instruction is 2 points of rotations, if coordinate points P_1-0 (x_1-0,y_1-0) represent one of initial time touch point coordinates, coordinate points P_2-0(x_2-0,y_2-0) represent initial time another Touch point coordinates, coordinate points P_1-t(x_1-t,y_1-t) represent one of current time touch point coordinates, coordinate points P_2-t(x_2-t,y_2-t) Represent another touch point coordinates at current time.Coordinate points P_1-0、P_2-0Constitute vector V₀, coordinate points P_1-t、P_2-tConstitute vector V_t, then the variation for the vector that two input points are constituted is：

In above formula, initial time two touches the vectorial V that point coordinates is constituted₀Point coordinates is touched with current time two to be constituted Vectorial V_tBetween angle absolute value representation be rotational steps Δ θ, using Δ θ as the size of parameter variation value.

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value pi/2 rotates the maximum rotational steps of gesture using depth of three-dimensional content value is adjusted, because The rotational steps of two fingers of user are limited under regular situation, and disposable rotation angle range is to hold within ± pi/2 It is facile；Certainly, maximum amplitude value may be set to be other values.

From the above equation, we can see that when the rotational steps Δ θ of the operation instruction is not more than maximum rotational steps pi/2, ratio is adjusted Example is ratio between two：When the rotational steps Δ θ of the operation instruction is more than maximum amplitude value pi/2, ratio is adjusted most Greatly, value 1.Understand that the value of Mar meets：0≤Mar≤1.

It is assumed that the vector that two input points that the first predetermined trend is the operation instruction are constituted rotates clockwise, second is pre- Determine the vector rotation counterclockwise that two input points that trend is the operation instruction are constituted（Vice versa）, then when the operation refers to It is worth to expected depth value plus depth adjustment with initial depth value when being shown as clockwise rotation gesture, when the operation instruction Depth adjustment is subtracted with initial depth value be worth to expected depth value when to rotate gesture counterclockwise.

When the operation instruction is clockwise rotation gesture, because initial depth value is Z₀, depth of three-dimensional content value is most It can be adjusted to Z greatly_Max, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,_Max-Z₀).It is expected that depth value can table It is shown as：

Z_t=Z₀+Mar×(Z_Max-Z₀) （4-3）

When the operation instruction is rotation gesture counterclockwise, because initial depth value is Z₀, depth of three-dimensional content value is most It is small to can be adjusted to Z_Min, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,₀-Z_Min).It is expected that depth value can table It is shown as：

Z_t=Z₀-Mar×(Z₀-Z_Min) （4-4）

Example IV, a kind of adjusting method of depth of three-dimensional content value, the embodiment are adjusted three-dimensional by range sensor Content depth value；Assuming that input body is palm, when user's mobile palm within the scope of the detecting distance of range sensor, it is considered as Have received the depth adjustment trigger signal.The operation instruction is single point gesture, and the mobile range of palm is：

Δd=|l_t-l₀|（5-1）

In above formula, l₀Palm that initial time range sensor is detected is represented to the distance of display screen, l_tIndicate current The distance of palm detected by moment range sensor to display screen.The absolute value of the difference of the distance of the two becomes as parameter The size delta d of change value.

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value l_MaxThe maximum distance that can be detected using range sensor.User is in display screen Front palm mobile range Δ d meets：0≤Δd≤l_Max.Understand that the value of Mar meets：0≤Mar≤1.

It is assumed that the first predetermined trend is the separate display screen of palm, the second predetermined trend is palm close to display screen（Instead Also may be used）, then when the operation instruction, which is that user's palm is separate, shows screen, it is worth plus depth adjustment with initial depth value To expected depth value；When the operation instruction, which is that user's palm is separate, shows screen, depth tune is subtracted with initial depth value Section is worth to expected depth value.

When the operation instruction, which is that user's palm is separate, shows screen, because initial depth value is Z₀, stereo content depth Angle value maximum can be adjusted to Z_Max, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,_Max-Z₀).It is expected that depth Value is represented by：

Z_t=Z₀+Mar×(Z_Max-Z₀) （5-3）

When the operation instruction, which is that user's palm is close, shows screen, because initial depth value is Z₀, stereo content depth Angle value minimum can be adjusted to Z_Min, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,₀-Z_Min).It is expected that depth Value is represented by：

Z_t=Z₀-Mar×(Z₀-Z_Min) （5-4）

Embodiment five, a kind of adjusting method of depth of three-dimensional content value, the embodiment are adjusted three-dimensional by pressure sensor Content depth value；It is considered as when user, which presses, shows screen and has received the depth adjustment trigger signal, the operation instruction is Single-point presses, and pressing amplitude is：

ΔN=|N_t-N₀| （6-1）

In above formula, N₀The pressure that initial time pressure sensor is detected is represented, because of initial time i.e. user hand At the time of referring to just contact display screen, it is known that its value is 0.During user's finger is increased to the pressure of display screen application N_tIndicate the pressure that current time pressure sensor is detected；In the process that the pressure that user's finger applies display screen reduces Middle N_tIt remains unchanged.The absolute value of the difference of the two is the pressing amplitude that user's finger pressing shows screen, as parameter variation value Size delta N.

Current adjusting ratio Mar can be calculated：

In above formula, maximum amplitude value N_MaxThe maximum pressure value of screen, N are pressed using user's finger under regular situation_Max's Value is within the scope of the maximum pressure that pressure sensor can be detected.From the above equation, we can see that user's finger pressing shows pressing for screen Amplitude, ao N is pressed to be not more than maximum amplitude value N_MaxWhen, it is ratio between two to adjust ratio Mar；User's finger pressing shows pressing for screen Amplitude, ao N is pressed to be more than set maximum amplitude value N_MaxWhen, it is 1 to adjust ratio Mar.Understand that the value of Mar meets：0≤Mar ≤1。

It is assumed that the first predetermined trend, which is finger pressing, shows screen.Then when the operation instruction is user's finger pressing display When screen, because initial depth value is Z₀, depth of three-dimensional content value maximum can be adjusted to Z_Max, so depth of three-dimensional content value is real The adjustable range on border is (Z_Max-Z₀).It is expected that depth value be represented by：Z_t=Z₀+Mar×(Z_Max-Z₀) （6-3）

When the operation instruction is that user's finger pressing shows screen, because initial depth value is Z₀, stereo content depth Angle value minimum can be adjusted to Z_Min, so it is (Z that depth of three-dimensional content, which is worth actual adjustable range,₀-Z_Min).It is expected that depth Value is represented by：

Z_t=Z₀-Mar×(Z₀-Z_Min) （6-4）

Since the input attribute of pressure sensor is limited, merely using pressure variety as Parameters variation amount when, solid in Hold depth value and only supports a kind of variation tendency（Increase depth of three-dimensional content value or reduces depth of three-dimensional content value）.Based on this Characteristic can also particularly be operated when pressure reaches vertex value, such as when pressure value reaches preset maximum pressure threshold When value, it is changed to two-dimentional display mode, is equivalent to and depth value is zeroed, user is allow to restart to adjust.

Current adjusting ratio Mar can be calculated：

Because initial depth value is Z₀, depth of three-dimensional content value maximum can be adjusted to Z_Max, so depth of three-dimensional content value is real The adjustable range on border is (Z_Max-Z₀).It is expected that depth value be represented by：

Z_t=Z₀+Mar×(Z_Max-Z₀) （7-3）

When user wishes to reduce the depth value of stereo content, the operation instruction is that finger pressing shows screen, at this time Pressure sensor can detect the pressure change of finger pressing screen：

ΔN=|N_t-N₀| （7-4）

In above formula, N₀The pressure that initial time pressure sensor is detected is represented, because of initial time i.e. user hand At the time of referring to just contact display screen, it is known that its value is 0.During user's finger is increased to the pressure of display screen application N_tIndicate the pressure that current time pressure sensor is detected；In the process that the pressure that user's finger applies display screen reduces Middle N_tIt remains unchanged.The absolute value of the difference of the two is expressed as finger pressing amplitude, ao N, and Δ N is also as the size of parameter variation value.
