Abstract

PURPOSE:To provide a means which can easily improve the operability of a mouse device with use of any type of devices and without requiring any special device. CONSTITUTION:An arithmetic part 4 receives the moved amount data outputted from a mouse 1 via a reception buffer 2 and estimates the time when the moving speed of the mouse 1 is equal to zero based on the received moved amount data and the characteristic value received from a characteristic holding part 3 which holds the characteristic value proper to the mouse 1. Then, the face contact state of the mouse 1 is detected. If the mouse face is separates from a plane, the moved amount data used for estimation of the separating time are outputted to a system processing part 5. Then, a cursor is shown on a display part 6. Therefore, it is possible to detect the mouse face contact state with use of an ordinary mouse, to use the output obtained by an optional function as long as the mouse is kept separated from a plane, and to easily apply the mouse face contact detecting method to a mouse device having various characteristics.

【Example】

Example 1. FIG. 1 is a block diagram showing an embodiment of a mouse controller according to the present invention. In FIG. 1, reference numeral 1 denotes a reception buffer for receiving mouse movement amount data (Δx, Δy) sampled at a predetermined sampling interval tS,
2 is a characteristic holding unit that holds a characteristic value specific to the type of mouse in advance, and 3 is a movement amount data (Δx, Δy) output from the reception buffer 1 and a characteristic value from the characteristic holding unit 2 that is used for calculation and grounding. A determination unit for determining the state, 4 is a system processing unit, and 6 is a display unit.

Next, the operation of the first embodiment will be described. The mouse 1 outputs movement amount data (Δx, Δy) of the X-direction and Y-direction components of the speed at which the mouse is moved. This movement amount data (Δx, Δy) is input to the reception buffer 2 and temporarily held, then sent to the system processing unit 4 and processed to display the movement of the cursor on the display unit 5.

On the other hand, the movement amount data (Δx, Δy) from the reception buffer 2 is also sent to the arithmetic unit 3, and the arithmetic unit 3
Based on the movement amount data (Δx, Δy) and the characteristic value peculiar to the mouse read from the characteristic holding unit 2, the prediction calculation of the time when the movement amount data becomes zero is performed.

Here, the characteristic value peculiar to the mouse held by the characteristic holding unit 2 will be described. FIG. 2 is a diagram showing an example of characteristics of a mouse, and FIG. 2 (a) is a diagram showing characteristics of a mechanical mouse, for example, a mouse that has a rotating body and outputs a moving speed by rotation of the rotating body. . In addition, FIG.
FIG. 6 is a diagram showing an example of characteristics of an optical mouse.

First, the characteristics of the mechanical mouse of FIG. 2A will be described. When the mouse is in contact with a surface on a desk and is moving, the speed characteristic (the portion A in FIG. 2A, hereinafter referred to as characteristic A) is shown, and the mouse is moved away from the surface in contact at time t0. And the rotating body show a characteristic (the portion B in FIG. 2A, hereinafter referred to as characteristic B) in which the speed rapidly decreases due to friction with the case of the mouse. If the moving speed of the mouse at this time t0 is v0, the speed vt after t seconds becomes vt = v0-α1t, and the speed becomes zero after Δt1. Here, the characteristic value α1 indicates acceleration.

At time t0, when the mouse is released from the hand and slid on the surface, the speed decreases due to the friction between the rotating body and the plane (the portion C in FIG. 2A, hereinafter referred to as characteristic C). . Similarly to the above, the velocity vt after t seconds becomes vt = v0-.alpha.2t, and the velocity becomes zero after .DELTA.t2.

In general, since α1 takes a considerably larger value than α2, the relationship between time and speed is as shown by characteristics B and C in FIG.

At the time t0, when the mouse is held with the hand and is made to stand still, the speed decelerates abruptly as when the mouse is released from the surface, but since it is held by the hand, it is shown in FIG. 2 (a).
The velocity does not converge to zero immediately like the part D of.

Next, the characteristics of the optical mouse which emits the light of FIG. 2B to the contact surface and receives the reflected light to output the moving speed will be described. When the mouse is moved away from the reflector at time t0, the same speed as when the mouse is continuously in contact with the reflector is detected while the distance from the reflector is short, but when the distance from the reflector increases (after Δt1). , The mouse can no longer detect the reflected light and the speed suddenly becomes zero.

Characteristics of the above mouse ((a) of FIG. 2)
In (b)), the portions of characteristic B and characteristic C show characteristic values specific to the type of mouse. Therefore, if the characteristic values α1 and α2 representing the characteristic B and the characteristic C are known in advance, the time when the speed becomes zero can be predicted.

That is, the time Δt1 from when the mouse is released from the surface until the velocity becomes zero is Δt1 = v0 / α1, and the time until the velocity becomes zero when the mouse is released from the hand and slid on the surface. Δt2 is Δt2 = v0 / α2.

Therefore, if α such that α2 <α ≦ α1 is predetermined, the time when the speed becomes zero can be predicted. The predicted time ΔT until the speed becomes zero is Δt1 <Δ
The relationship is T <Δt2. Whether or not the mouse is on the surface is determined by continuously measuring whether or not the velocity at this ΔT is zero.

Since the output data from the mouse is the amount of movement per unit time, when the unit time is long, the apparent characteristics are from the characteristics B of FIG. 2 (b) to the characteristics B of FIG. 2 (a).
Various characteristics such as are detected.

However, when the unit time is Δt, 2Δ
Since it always converges to zero within t, it is easy to set ΔT, and whether or not the mouse is on the surface can be determined by continuously measuring whether or not the velocity at ΔT is zero.

Then, the characteristic value α of such a mouse is provided in the characteristic holding unit 2 in advance, so that the movement amount data (Δx, Δ) input from the reception buffer 1 in the arithmetic unit 3 is obtained.
Based on y) and the characteristic value α of the characteristic holding unit 2, a calculation for predicting a time T0n until the velocity becomes zero is performed from the movement amount data (Δx, Δy) at a certain time tn. T0n = (Δx2 + Δy2) 1/2 / α

The predicted time for each sampling calculated by the above equation is rounded up and stored in the table together with the movement amount data at that time. Then, when the input movement amount data at a certain sampling time is zero, it is searched and stored if the predicted time at which the velocity becomes zero at the current sampling time is stored in the sampling calculation before that time. For example, it is determined that the mouse is not in contact with the face. Then, the movement amount data at the time of predicting the matching predicted time is output to the system processing unit 5. The system processing unit 5 processes based on this data and sends it to the display unit 6 to display a cursor. This will be described in detail with reference to the storage table shown in FIG. 3 and the flowchart of FIG. The table of FIG. 3 shows a table of depth 7, and has a storage area of movement amount data D (x) and D (y) at each sampling and a predicted time P (t) which becomes zero.

Movement amount data Δx from the reception buffer 2,
Δy is taken in and stored in the table of the calculation unit (steps 41 and 42). If the fetched movement amount data is not zero, a prediction calculation of the time at which the velocity becomes zero is performed from the characteristic value α held in the characteristic holding unit 3 and the movement amount data Δx, Δy just fetched (step 43), and the calculation is performed. The result prediction time is rounded up to the nearest whole number and stored in the table (steps 44 and 45).

Next, when the fetched movement amount data Δx and Δy are zero, the table is searched and the predicted time P (t) stored in the table up to that time is compared with the current sampling time. (Step 46), and if the matching predicted time is stored, the movement amount data D (x) and D (y) at that time are read out and held (step 4).
7). If there is data having a value larger than the movement amount data held in the subsequent search, that data is held (step 4).
7).

When the table search is completed (completed), the held D (x) and D (y) are sent to the system processing section (step 48). That is, when there is the same predicted time, the one with the highest moving speed is output.

Here, a detailed description will be given with reference to FIG.
When the input movement amount data ΔX6 and ΔY6 are zero at time 6, the prediction time column P (t) is searched, and, for example, when the predicted value tp3 is equal to time 6, when tp3 is predicted and calculated (time 3). The used movement amount data ΔX3 and ΔY3 are output.

Example 2. Although the time when the movement amount data D (x) and D (y) become zero is predicted and calculated in the first embodiment, the number of times of sampling may be calculated. That is, the number of sampling times required to reach zero may be calculated and stored in the table.

Example 3. Further, in the above-described first embodiment, when the same predicted time is present, the largest movement amount is held and output to the system processing unit. However, the average value of the movement amount at the same predicted time is output. May be.

Example 4. In the first embodiment described above, the characteristics corresponding to various mice are previously checked and stored in the characteristic value holding unit 2, but in the fourth embodiment, the characteristics of the connected mouse are measured and the measurement results An example of controlling based on the characteristics will be described. FIG. 5 is a block diagram corresponding to the fifth embodiment. In FIG. 5, reference numeral 7 denotes an input unit, which is an input unit such as a personal computer, and 8 measures the characteristics of a mouse according to a characteristic measurement instruction input through the input unit 7. It is a measuring unit. Other parts are the same as in FIG. In addition, FIG.
Is the flowchart.

Next, the operation of mouse characteristic measurement will be described. When the operator inputs a mouse characteristic measurement instruction from the input unit 6, the system processing unit 5 outputs a measurement instruction signal to the measurement unit 8 to enter the measurement mode. In the measurement mode, the operator lifts the mouse while moving it on a surface such as a desk at a substantially constant speed. By this operation, the movement amount data corresponding to the characteristic shown in FIG. 2 is input to the reception buffer 2, the movement amount data is fetched from the reception buffer 2 to the characteristic measuring unit 8, and the data from the reception buffer 2 is continuously monitored. A point where the numerical value suddenly decreases is detected, and this is the mouse release point ((t0) in Fig. 2).
Then, a point at which the movement amount data becomes zero is detected, and this is taken as a stationary point ((t1) in FIG. 2) to obtain the acceleration .alpha.M from V0 at t0 (step 61), which is sent to the characteristic holding unit 3 and stored therein. (Step 62).

If the numerical value does not converge to zero even after a lapse of a certain period of time, it is judged that the detection of the mouse emission point is wrong and the detection of the mouse emission point is started again.

While the mouse characteristic is being measured in the system processing section 5, the operator is made to determine whether or not the determination result of the mouse grounding by the calculating section 4 is correct, and the mouse characteristic measuring section is instructed by the input from the input section 7 to confirm the result. Tell 8.

Then, if the result is good, if the measured characteristic value is already held, a new average value of the measured characteristic value and the measured characteristic value is obtained and transmitted to the characteristic holding unit (step 65). The concrete calculation formula is as follows. If the number of measurements so far is n, the average characteristic value of the characteristic values so far is αn, and the characteristic value measured this time is αM, the new average characteristic value is αn + 1 = ( It can be obtained by nαn + αM) / (n + 1).

If the measurement result is not good, the measured characteristic value is discarded (step 66).

When the operator determines that the characteristic measurement of the mouse is completed, the termination instruction input from the input section 8 is transmitted to the characteristic measurement section 7 via the system processing section 5, and the measurement is performed by then. Then, the obtained average characteristic value α is transmitted to the characteristic holding unit 3 (step 67).

Then, based on this characteristic value, it is detected whether or not the mouse is in contact, and when the mouse is not in contact, the movement amount data is sent out in the same manner as in the above-mentioned embodiment.

Example 5. In the first and second embodiments, when the speed becomes zero at the prediction time, the one showing the largest speed is output from the movement amount data captured when the prediction calculation is performed. An example of outputting movement amount data based on a function stored in advance will be described.

FIG. 7 is a flow chart of this embodiment. When the mouse is in the grounded state, data is sent from the reception buffer 2 to the system processing section 5 and the cursor is displayed on the display section 6. When it is determined that the mouse is not in the grounded state, the movement amount data to be output is calculated by the function stored in advance or the function (fx, fy) that can be arbitrarily set, and the value is transmitted as the movement amount.

For example, if a function expressed by the following equation is used as an example of the function to be stored in advance, the deceleration due to constant friction is simulated, so that the cursor can be displayed naturally. Where the velocity at the time of release is v
x0 and vy0. fx (t) = vx0−αxt fy (t) = vy0−αyt

However, when the unit time (measurement interval) is Δt, it always converges to 0 within 2Δt.
It is easy to set T (207), and it is determined whether or not the mouse is on a plane by continuously measuring whether or not the velocity at ΔT (207) is zero.

[0054]

As described above, according to the present invention, since the state detecting section for holding the output characteristic of the mouse is provided, the grounding state of the mouse which has been conventionally detected by using a special device can be detected. There is an effect that can be obtained without using a special device.

Further, according to the present invention, when the mouse device is not in contact with the plane, its output is calculated by a speed at the time when the mouse device is separated from the plane or a function having an arbitrary speed as an initial speed, and Since the function can be changed arbitrarily, there is an effect that a free user interface can be provided depending on the use environment and application.

Further, according to the present invention, the output characteristic of the mouse device used by the state detecting section is automatically measured and stored by the operator's instruction, so that the mouse can be grounded to any mouse device. This has the effect of easily providing a state detection function.
