Such as when described operation is designated as single point movement, described adjusting ratio is displacement and the ratio of predetermined amplitude peak value; Described displacement is the distance between input point current location and the position while receiving described depth adjustment trigger pip.

For another example when described operation is designated as at 2 while sliding, the ratio of the variable quantity that described adjusting ratio is two input point distances and predetermined amplitude peak value; The variable quantity of described two input point distances is the absolute value of the difference of the distance of two the input point current times distance when receiving described depth adjustment trigger pip.

When described operation is designated as 2 rotations, described adjusting ratio is for another example

In the present embodiment, described amplitude peak value can be definite value, also can be according to regulating fineness to change; Different amplitude peak value corresponding to adjusting fineness; Described adjusting fineness is higher, and corresponding amplitude peak value is larger.

Because the performance accuracy of staff or finger is limited, be difficult to accurately grasp amplitude of variation; Therefore,, when needs are finely tuned the degree of depth, can select higher adjusting fineness, the amplitude peak value corresponding due to higher adjusting fineness is larger, therefore for same parameter changing value, resulting adjusting ratio is less, and degree of depth adjusted value is also just corresponding less.

During such as low adjusting fineness, corresponding amplitude peak value is 10 centimetres, and when operation is designated as single point movement and displacement and is 1 centimetre, adjusting ratio is 0.1, and degree of depth adjusted value is range of adjustment 1/10th; And high while regulating fineness corresponding amplitude peak value be 50 centimetres, when operation is designated as single point movement and displacement and is 1 centimetre, adjusting ratio is 0.02, degree of depth adjusted value is range of adjustment 1/50th; Visible, even in the situation that adopting hand or finger as input body, can carry out point-device depth adjustment too.

Maximum adjustable-depth: Z _max(constant);

Minimum adjustable-depth: Z _min(constant).

In an embodiment of the present embodiment, when the input gesture detecting in viewing area is that single-point touches (can be singly to refer to, also can be many fingers of gathering on one point, can also be the input point that other input body forms) time, be considered as having received described depth adjustment trigger pip.Described operation is designated as single point movement, and the displacement of input point is:

$\mathrm{\Δl}=\sqrt{{(x_{1-t}-x_{1-0})}^2+{(y_{1-t}-y_{1-0})}^2}---\left(0\right)$

In above formula, coordinate points P _1-0(x _1-0, y _1-0) represent the touch point coordinate of initial time, coordinate points P _1-t(x _1-t, y _1-t) represent the touch point coordinate of current time.Sliding distance when user's input gesture is slip gesture is expressed as slip amplitude, ao l, the size using Δ l as parameter changing value.

When described operation is designated as horizontal slip gesture, (y _1-t-y _1-0) value can ignore, so Δ l is can abbreviation as follows:

Δl＝|x _1-t-x _1-0| （1-1）

Can calculate current adjusting ratio Mar:

$\mathrm{Mar}=\left\{\begin{array}{cc}\frac{\mathrm{\Δl}}{\mathrm{WndWidth}}& (\mathrm{\Δl}\≤\mathrm{WndWidth})\\ 1& (\mathrm{\Δl}>\mathrm{WndWidth})\end{array}\right.---(1-2)$

In above formula, amplitude peak value WndWidth adopts the width value of current stereo content display window.Suppose that, in the process of Primary regulation stereo content depth value, the width value of current stereo content display window is constant.From above formula, when the horizontal slip amplitude, ao l of described operation indication is not more than the width value of current stereo content display window, adjusting ratio is ratio between two: when the horizontal slip amplitude, ao l of described operation indication is greater than the width value of current stereo content display window, adjusting ratio is maximum, and its value is 1.The value of known Mar meets: 0≤Mar≤1.

Suppose that the first predetermined trend is that level is slided to the right, the second predetermined trend is level slide left (vice versa), when described operation is designated as level and slides, by initial depth value, add that depth adjustment value obtains the depth value of expection to the right, described operation is designated as level by initial depth value deducts depth value that depth adjustment value obtain expection while sliding left.

When described operation is designated as level and slides to the right, because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is (Z _max-Z ₀).So the depth value of expection can be expressed as:

Z _t＝Z ₀+Mar×(Z _Max-Z ₀) （1-3）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When described operation is designated as level and slides left, because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Z _t＝Z ₀-Mar×(Z ₀-Z _Min) （1-4）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.

To sum up, the depth value Z of expection _texpression formula as follows:

When described operation is designated as vertical slip gesture, (x _1-t-x _1-0) value can ignore, so Δ l is can abbreviation as follows:

Δl＝|y _1-t-y _1-0| （2-1）

Can calculate current adjusting ratio Mar:

$\mathrm{Mar}=\left\{\begin{array}{cc}\frac{\mathrm{\Δl}}{\mathrm{Wndlength}}& (\mathrm{\Δl}\≤\mathrm{Wndlength})\\ 1& (\mathrm{\Δl}>\mathrm{Wndlength})\end{array}\right.---(2-2)$

In above formula, amplitude peak value Wndlength adopts the height value of current stereo content display window.Suppose that, in the process of Primary regulation stereo content depth value, the length value of current stereo content display window is constant.From above formula, when the vertical slip amplitude, ao l of described operation indication is not more than the height value of current stereo content display window, adjusting ratio is ratio between two: when the vertical slip amplitude, ao l of described operation indication is greater than the height value of current stereo content display window, adjusting ratio is maximum, and its value is 1.The value of known Mar meets: 0≤Mar≤1.

Suppose that the first predetermined trend is for sliding straight up, the second predetermined trend is slide straight down (vice versa), when described operation is designated as while sliding straight up, by initial depth value, add that depth adjustment value obtains the depth value of expection, when described operation is designated as while sliding straight down, by initial depth value, deduct the depth value that depth adjustment value obtains expection.

When described operation is designated as while sliding straight up, because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is Z _max-Z ₀.So the depth value of expection can be expressed as:

Z _t＝Z ₀+Mar×(Z _Max-Z ₀) （2-3）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When described operation is designated as while sliding straight down, because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Z _t＝Z ₀-Mar×(Z ₀-Z _Min) （2-4）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.

To sum up, the depth value Z of expection _texpression formula as follows:

In the another kind of embodiment of the present embodiment, when the input gesture detecting in viewing area is 2 touches and variable in distance, be considered as having received described depth adjustment trigger pip.Described operation is designated as 2 slips, the variable in distance amount of two input points (being touch point):

$\mathrm{\Δ}{l}^{\′}=|\sqrt{{(x_{1-t}-x_{2-t})}^2+{(y_{1-t}-y_{2-t})}^2}-\sqrt{{(x_{1-0}-x_{2-0})}^2+{(y_{1-0}-y_{2-0})}^2}|---(3-1)$

In above formula, coordinate points P _1-0(x _1-0, y _1-0) represent a touch point coordinate of initial time, coordinate points P _2-0(x _2-0, y _2-0) represent another touch point coordinate of initial time, coordinate points P _1-t(x _1-t, y _1-t) represent a touch point coordinate of current time, coordinate points P _2-t(x _2-t, y _2-t) represent another touch point coordinate of current time.The absolute value of the line segment distance between current time two touch points and the difference of the line segment distance between touch point of the initial moment two is as the size delta l' of described parameter changing value.

In above formula, amplitude peak value WndWidth adopts the width value of current stereo content display window.Suppose that, in the process of Primary regulation stereo content depth value, the width value of current stereo content display window is constant.From above formula, when the variable in distance amount Δ l' of two input points of described operation indication is not more than the width value of current stereo content display window, adjusting ratio is ratio between two:

when the variable in distance amount Δ l' of two input points of described operation indication is greater than the width value of current stereo content display window, adjusting ratio is maximum, and its value is 1.The value of known Mar meets: 0≤Mar≤1.

Suppose that the first predetermined trend is that the distance of two input points becomes large, the second predetermined trend is the distance of two input points diminish (vice versa), when the distance of two input points of described operation indication becomes large, by initial depth value, add that depth adjustment value obtains the depth value of expection; When the distance of two input points of described operation indication diminishes, by initial depth value, deduct the depth value that depth adjustment value obtains expection.

When the distance of two input points of described operation indication becomes large (such as the gesture of described operation indication is amplifying gesture), because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is (Z _max-Z ₀).So the depth value of expection can be expressed as: Z _t=Z ₀+ Mar * (Z _max-Z ₀) (3-3)

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When the distance of two input points of described operation indication diminishes (such as user inputs gesture for dwindling gesture), because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Z _t＝Z ₀-Mar×(Z ₀-Z _Min) （3-4）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.

To sum up, the depth value Z of expection _texpression formula as follows:

In an embodiment of the present embodiment, when the input gesture detecting in viewing area is 2 gestures that touch and rotate, be considered as having received described depth adjustment trigger pip.Described operation is designated as 2 rotations, establishes coordinate points P _1-0(x _1-0, y _1-0) represent a touch point coordinate of initial time, coordinate points P _2-0(x _2-0, y _2-0) represent another touch point coordinate of initial time, coordinate points P _1-t(x _1-t, y _1-t) represent a touch point coordinate of current time, coordinate points P _2-t(x _2-t, y _2-t) represent another touch point coordinate of current time.Coordinate points P _1-0, P _2-0form vectorial V ₀, coordinate points P _1-t, P _2-tform vectorial V _t, two vectorial being changed to that input point forms:

In above formula, amplitude peak value pi/2 adopt to regulate the maximum rotation amplitude of stereo content depth value rotate gesture because the rotation amplitude of user's two fingers is limited under regular situation, and disposable rotation angle range ± pi/2 with interior be hold facile; Certainly, amplitude peak value also can be set to other value.

From above formula, when the rotation amplitude, ao θ of described operation indication is not more than maximum rotation amplitude pi/2, adjusting ratio is ratio between two:

when the rotation amplitude, ao θ of described operation indication is greater than amplitude peak value pi/2, adjusting ratio is maximum, and its value is 1.The value of known Mar meets: 0≤Mar≤1.

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When described operation is designated as while being rotated counterclockwise gesture, because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

In above formula, amplitude peak value l _maxthe ultimate range that adopts range sensor to detect.User palm mobile range Δ d before display screen meets: 0≤Δ d≤l _max.The value of known Mar meets: 0≤Mar≤1.

Suppose that the first predetermined trend is that palm is away from display screen, the second predetermined trend is that palm is near display screen (vice versa),, when described operation is designated as user's palm away from display screen, by initial depth value, add that depth adjustment value obtains the depth value of expection; When described operation is designated as user's palm away from display screen, by initial depth value, deduct the depth value that depth adjustment value obtains expection.

When described operation is designated as user's palm away from display screen, because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is (Z _max-Z ₀).So the depth value of expection can be expressed as:

Z _t＝Z ₀+Mar×(Z _Max-Z ₀) （5-3）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When described operation is designated as user's palm near display screen, because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Z _t＝Z ₀-Mar×(Z ₀-Z _Min) （5-4）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.

ΔN＝|N _t-N ₀| （6-1）

In above formula, N ₀represent the pressure that initial time pressure transducer detects because initial time namely user finger rigidly connect the moment of touching display screen, known its value is 0.N in process display screen applied pressure being increased at user's finger _trepresent the pressure that current time pressure transducer detects; N in process display screen applied pressure being reduced at user's finger _tremain unchanged.The amplitude of pressing that the absolute value of both differences is user's finger presses display screen, as the size delta N of parameter changing value.

Can calculate current adjusting ratio Mar:

$\mathrm{Mar}=\left\{\begin{array}{cc}\frac{\mathrm{\&Delta;N}}{N_{\mathrm{Max}}}& (\mathrm{\&Delta;N}\&le;N_{\mathrm{Max}})\\ 1& (\mathrm{\&Delta;N}>N_{\mathrm{Max}})\end{array}\right.---(6-2)$

In above formula, amplitude peak value N _maxadopt the maximum pressure value of user's finger presses screen under regular situation, N _maxthe value maximum pressure that can detect at pressure transducer within the scope of.From above formula, the amplitude, ao N that presses of user's finger presses display screen is not more than amplitude peak value N _maxtime, regulating ratio Mar is ratio between two; The amplitude, ao N that presses of user's finger presses display screen is greater than the amplitude peak value N setting _maxtime, regulating ratio Mar is 1.The value of known Mar meets: 0≤Mar≤1.

Suppose that the first predetermined trend is finger presses display screen.When described operation is designated as user's finger presses display screen, because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is (Z _max-Z ₀).So the depth value of expection can be expressed as: Z _t=Z ₀+ Mar * (Z _max-Z ₀) (6-3)

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When described operation is designated as user's finger presses display screen, because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.

To sum up, the depth value Z of expection _texpression formula as follows:

Because the input attributes of pressure transducer is limit, using merely pressure variety during as parameter variable quantity, stereo content depth value is only supported a kind of variation tendency (increase stereo content depth value or reduce stereo content depth value).Based on this specific character, can also work as when pressure arrives summit value and operate especially, when arriving default maximum pressure threshold value when force value, change to two-dimentional display mode, be equivalent to depth value to make zero, make user can restart adjustment.

First need to suppose that any sensor controls any regulative mode.Suppose when described operation is designated as finger presses display screen and reduce to save stereo content depth value by pressure transducer; When being designated as palm away from display screen, described operation increases stereo content depth value by range sensor.(two kinds regulative mode exchange also can).

When user wishes to increase stereo content depth value, described operation is designated as mobile palm in the detection distance range of range sensor, and now range sensor can detect palm apart from the variable in distance of display screen:

Because initial depth value is Z ₀, stereo content depth value maximum can be adjusted to Z _maxso the range of adjustment of stereo content depth value reality is (Z _max-Z ₀).So the depth value of expection can be expressed as:

Z _t＝Z ₀+Mar×(Z _Max-Z ₀) （7-3）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z ₀≤ Z _t≤ Z _max.

When user wishes to reduce the depth value of stereo content, described operation is designated as finger presses display screen, and now pressure transducer can detect the pressure variation of finger presses screen:

ΔN＝|N _t-N ₀| （7-4）

In above formula, N ₀represent the pressure that initial time pressure transducer detects because initial time namely user finger rigidly connect the moment of touching display screen, known its value is 0.N in process display screen applied pressure being increased at user's finger _trepresent the pressure that current time pressure transducer detects; N in process display screen applied pressure being reduced at user's finger _tremain unchanged.The absolute value representation of both differences is finger presses amplitude, ao N, and Δ N is also as the size of parameter changing value.

Because initial depth value is Z ₀, stereo content depth value minimum can be adjusted to Z _minso the range of adjustment of stereo content depth value reality is (Z ₀-Z _min).So the depth value of expection can be expressed as:

Z _t＝Z ₀-Mar×(Z ₀-Z _Min) （7-6）

Because the span of the ratio of adjusting Mar is 0～1, known Z _tvalue meet: Z _min≤ Z _t≤ Z ₀.
