Description

Apparatus for processing pointing device data and method therefor}

The present invention relates to a pointing device displacement value processing apparatus and a method thereof. More particularly, the present invention relates to an apparatus and a method for processing a pointing device displacement value received from a remote control having a pointing device.

Pointing devices such as a mouse are being applied as a user interface for convenient use of general portable electronic devices.

Recently, many display devices (e.g., smart TVs) have been developed to emit a detection light and to detect an optical signal that changes according to the movement of a finger, which allows the user to move a pointer on the screen or to select a desired data. Or it is applied to the remote control for controlling the set-top box.

However, in the case of a conventional display device or a set-top box, it is possible to process a sensing value (that is, a pointing device displacement value) received from a remote control equipped with a pointing device to move a pointer on the screen or to select and execute data desired by a user. In doing so (see Fig. 1), the following problem occurred.

For example, the pointer does not move quickly on user's intention on the large screen, when the pointer is moved within a narrow range, the pointer is slightly shaken, or when the pointer moves, it may appear to be bouncing (pointer jumping), There was a problem that the correct click was not made when clicking a specific link on the screen.

An object of the present invention is to provide a method for solving the above-mentioned problems,

More specifically, when the user moves the pointer displayed on the large screen using the pointing device mounted on the remote controller, the inconvenience of having to repeatedly move the finger several times during long distance movement is minimized, and more precise pointer when the short distance movement is performed. Provides a method to enable manipulation.

In addition, when a user moves a pointer displayed on a large screen using a pointing device mounted on a remote controller, a method for preventing the pointer on the screen from moving in a non-linear movement (pointer jumping) is provided.

In addition, when the user moves the pointer on the large screen using the pointing device mounted on the remote control, there is provided a method for enhancing the user's pointing device operation feeling.

In addition, the present invention provides a method of preventing a pointer shaking on a screen (Trembling / Jiggling) from occurring when a pointer is moved near a large screen using a pointing device mounted on a remote controller.

In addition, when searching for a list including a plurality of items displayed on the screen by using a pointing device, a method for enabling items to be searched at a high speed is provided.

In addition, when searching for a list including a plurality of items displayed on the screen by using the pointing device, the sound output when the scrolling device is changed according to the size and number of items constituting the menu may be used. It provides a way to increase.

The pointing device displacement value processing apparatus according to the present invention reduces the moving distance of the pointer by applying a deceleration factor to the displacement value when the displacement value of the pointing device falls within the area A, and when the displacement value belongs to the area B, Acceleration factor is applied to the displacement value to increase the moving distance of the pointer.

Also, based on the displacement value of the pointing device, before moving the pointer from the a position to the a 'position, the intermediate values are interpolated between the a and a' positions so that the pointer is displayed in linear motion without jumping.

In addition, additional movement is added to the movement of the pointer according to the acceleration factor (Facc) and the screen resolution, so that the movement of the pointer is naturally expressed when the hand is released after the pointing device is manipulated.

In addition, among the displacement values of the pointing device sensed during the unit time, the small displacement values that are opposite to the direction in which the fingers are moved are ignored, so that the pointer is displayed as a stable movement without trembling / jigging.

Also, the scroll value of the cursor is determined corresponding to the number of items included in the list displayed on the screen (when the number of items included in the list is large, the scroll value of the cursor is amplified).

Also, the sound output when scrolling varies according to the size and number of items constituting the menu. For example, a Dull sound is output when scrolling a menu composed of relatively few items, and a high pitch sound is output when scrolling a menu composed of relatively many items.

According to the embodiment of the present invention, the following effects are obtained.

When the user moves the pointer displayed on the large screen using a pointing device mounted on the remote controller, it is possible to minimize the inconvenience of repeatedly moving the finger several times during long distance movements, and to enable more precise pointer manipulation during the short distance movement. Can be.

In addition, when the user moves the pointer displayed on the large screen using the pointing device mounted on the remote controller, it is possible to prevent the pointer on the screen from moving in a nonlinear motion (pointer jumping).

The terms used in this specification will be briefly described and the present invention will be described in detail.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. Also, in certain cases, there may be a term selected arbitrarily by the applicant, in which case the meaning thereof will be described in detail in the description of the corresponding invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the contents throughout the present invention, rather than the names of the simple terms.

When an element is referred to as "including" an element throughout the specification, it is to be understood that the element may include other elements, without departing from the spirit or scope of the present invention. In addition, the terms "... unit", "module", etc. described in the specification mean a unit for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, a pointing device displacement value processing apparatus according to the present invention may be applied to a TV (eg, a smart TV) or a set-top box, and receives a pointing device displacement value transmitted from a remote controller 100 equipped with a pointing device. . In this case, the remote controller may further include a touch pad, a qwerty keyboard, and the like in addition to the pointing device.

The pointing device generates and moves a cursor or pointer on a TV screen through the movement of a finger so that the same pointing technology as in a personal computer (PC) is implemented. In addition, the pointing device allows the scroll function to move the displayed contents on the screen up or down or left or right.

For example, if you move your finger after raising your finger on a pointing device, the cursor on the TV screen moves according to the direction in which you move the finger. At this time, the pointing device can sense the physical contact of the finger or can sense the light reflected on the finger, thereby generating a motion detection signal (i.e., a pointing device displacement value).

Here, 'fingers' can be understood as other parts of the body, and even if the body is not a body, the pointing device can be another replaceable object capable of grasping the movement.

In this case, the pointing device may be implemented as an optical track pad (OTP), but may be implemented in various forms including an optical joystick, a hall sensor, a fingerprint sensor, and a pressure sensor. In addition, a dome click switch (Dome click S / W) that can detect the user's finger pressing operation may be provided.

Here, the optical track pad (OTP) is an optical mouse for a portable terminal, and is an optical pointing device that implements an optical mouse function used in a personal computer in a mobile device. The technology for such an optical touch pad (OTP) is a disclosed technology, and a detailed description thereof will be omitted.

The communication unit 210 receives the pointing device displacement value transmitted from the remote controller 100 and transmits the pointing device displacement value to the control unit 220. The communication unit 210 can be implemented through a communication method such as Zigbee, UART, RF, infrared, Bluetooth.

If the displacement value of the pointing device falls within the screen area A, the controller 220 reduces the moving distance of the pointer by applying a deceleration factor to the displacement value. When the displacement value falls within the area B, the controller 220 accelerates the displacement factor. Apply to increase the moving distance of the pointer (see Fig. 3).

Also, the controller 220 interpolates arbitrary intermediate values between the a and a 'positions before moving the pointer from the a position to the a' based on the displacement value of the pointing device so that the pointer is displayed as a linear movement without jumping. (See FIG. 4).

In addition, the controller 220 adds an additional movement to the movement of the pointer according to the acceleration factor Facc and the screen resolution so that the pointer movement is naturally expressed when the hand is released after the pointing device is manipulated (see FIG. 5).

In addition, the controller 220 ignores small displacement values that are opposite to the direction of finger movement among the displacement values of the pointing device detected during the unit time, so that the pointer is displayed as a stable movement without the Trembling / Jiggling phenomenon (see FIG. 6). ).

In addition, the controller 220 determines the scroll value of the cursor in response to the number of items included in the list displayed on the screen (when the number of items included in the list is large, the scroll value of the cursor is amplified) (see FIG. 7). .

In addition, the controller 220 varies the sound output when scrolling according to the size and number of items constituting the menu. For example, when scrolling a menu composed of relatively few items, a Dull sound is output, and when scrolling a menu composed of relatively many items, a high pitch sound is output (see FIG. 8).

The UI processing unit 300 provides a scrolling function to move a pointer on the screen or to search for items constituting a menu based on a value transmitted from the control unit 220 of the pointing device displacement value processing device 200. do.
