Abstract

PURPOSE:To easily control an equipment by obtaining the information relating to the input moving direction from the change of the time on the position information given to an input sensing means, thereby only designating the direction on the input sensing means. CONSTITUTION:An input sensing means 1 senses an input position and outputs the value as the coordinates in a 2-dimensional orthogonal coordinate system. The contact coordinate value is given to an input direction calculating means 3 from the input sensing means 1 at a fixed time interval with a time counting means 2. Then the means 3 calculates the component of an input direction vector from the input coordinate value received right before the calculation and the input coordinate value obtained at the present time point. An equipment control means 4 selects the equipment to be controlled and the control method based on the calculated input direction vector. Thus it is possible to obtain the equipment controller which gives instructions the input with the use of the information on the moving information not based on the position information but on the input moving direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device control device based on a direction of movement.

[Conventional technology]

Conventionally, an instruction to input device control information is given by pressing a specific key or clicking a mouse button.

[Problem to be solved by the invention]

In the conventional method as described above, only position information is used for input, so although it is accurate, there is a problem in that it is difficult to grasp intuitively.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such conventional drawbacks and to provide a device control device based on a moving direction that provides an input instruction using moving direction information rather than position information.

[Means to solve the problem]

The device control device based on the movement direction of the present invention includes an input sensing means for sensing an input position, a time measuring means for measuring time, and a time at the input position based on information from the input sensing means and the time measuring means. and an apparatus control means for controlling the apparatus based on information from the input direction calculation means.

[Effect]

The device control device based on the movement direction according to the present invention controls the device by obtaining information regarding the movement direction of the input by examining changes over time in position information on the input sensing means.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention.

The input sensing means 1 senses an input position and outputs a value as coordinates in a two-dimensional orthogonal coordinate system. The input direction calculating means 3 is given contact coordinate values from the input sensing means 1 at constant time intervals t by the time measuring means 2. The input coordinate value given immediately before (Xo.

yo), and the current input coordinate value is (xx + ys), the components (x, y') of the input direction vector are calculated by the input direction calculation means 3 using the following equation.

x = x1 - xO y = 'J l 3'.

The device control means 4 selects a device to be controlled and a control method based on the calculated input direction vector. After the control, the above-described process is repeated with x, l = xQ + yt = 310.

Note that depending on the case, the coordinate system may be limited to one dimension, or a three-dimensional or more coordinate system may be considered as necessary. Alternatively, a polar coordinate system may be used.

In the above, an information display device is considered as the device to be controlled. In this case, the device control means 4 moves the displayed image information in the direction calculated by the input direction calculation means 3. Of the pixels that were displayed before the movement, those whose coordinate values exceed those that can be displayed on the information display device after the movement are ignored. There are two methods for controlling the portion that will become blank after the movement by the device control means 4 as follows. One method is to assume that there is a virtual large screen and apply the above equation to pixels in areas that are not displayed before movement. The other method is to divide the display information into sections according to the size (pages) that can be displayed simultaneously on the information display device, and to fill in blank areas after the move with pages other than those that were displayed on the information display device before the move. This is a method of displaying part or all of a page.

Next, consider the case where multiple devices are selected. For example, assume that device 1, device 22, device 32, and device 4 are arranged vertically and horizontally in the selection menu on the information display device. At this time, according to the present invention, the direction in which the menu exists can be given to the input sensing means without specifying the position. The input direction calculation means 3 determines the up, down, left and right directions, and the device control means 4 selects the corresponding device based on this information. Note that the arrangement within the selection menu is not limited to the top, bottom, left, and right, but may be stored at an appropriate position as necessary.

Third, consider the case of changing the control amount of equipment.

For example, assume that an increase and a decrease are arranged above and below in a selection menu on an information display device. At this time, according to the present invention, the direction in which the menu exists can be given to the input sensing means 1 without specifying the position.The input direction calculation means 3 determines the up and down direction and based on this information. Then, the device control means 4 increases or decreases the controlled amount.

Note that the arrangement within the selection menu is not limited to the top and bottom, but may be stored at an appropriate position as necessary.

Fourth, consider the case of changing the control direction of equipment.

For example, assume that the control target space corresponds to the information display device. At this time, according to the present invention, the control direction may be given to the input sensing means 1.

The input direction calculation means 3 identifies the direction to be controlled, and based on this information, the device control means 4 controls in that direction.

Fifth, consider the output from the central controller to peripheral devices and the input from peripheral devices to the central controller. for example,
It is assumed that a central control unit and peripheral devices are arranged on the left and right sides of an information display device. At this time, according to the present invention, the direction in which information flows can be given to the input sensing means 1 without specifying the function of output or input as a position.

That is, in order to output from the central control unit (displayed on the left side of the information device) to the peripheral device (displayed on the right side of the information device), an instruction is given to the input sensing means 1 as a direction from the left side to the right side. Furthermore, in order to input from the peripheral device to the central control unit, it is sufficient to give an instruction to the input sensing means 1 as a direction from the right side to the left side.

The input direction calculation means 3 determines the left and right directions, and the device control means 4 selects input or output based on this information. Note that the placement within the selection menu is not limited to the left and right, but may be placed at an appropriate position as necessary. The same applies even if there are a plurality of peripheral devices.

〔Effect of the invention〕

According to the present invention, the device can be easily controlled by simply indicating a direction on the input sensing means.
