1 is a block diagram illustrating a configuration of a scroll control system according to an exemplary embodiment, and FIG. 2 is a flowchart illustrating a scroll method in the scroll control system according to an exemplary embodiment.

The processor included in the scroll control system 100 may include a touch sensing unit 110 , an input information obtaining unit 120 , and a scroll control unit 130 . The processor and its components may control the scroll control system to perform steps 210 to 230 included in the scrolling method of FIG. 2 . In this case, the processor and the components of the processor may be implemented to execute instructions according to the code of the operating system included in the memory and the code of at least one program. Here, the elements of the processor may be expressions of different functions performed by the processor according to a control command provided by the program code stored in the scroll control system 100 .

The processor may load the program code stored in the file of the program for the scrolling method into the memory. For example, when a program is executed in the scroll control system 100 , the processor may control the scroll control system to load a program code from a file of the program into the memory according to the control of the operating system.

In step 210 , the touch sensing unit 110 may detect whether the electronic device is touched by the user. The touch sensing unit 110 may determine that the touch sensor 110 is in an idle state by detecting that a meter is measured by the wheel of the input device.

In operation 220 , the input information acquisition unit 120 may acquire input information including information on whether or not the detected electronic device has been touched or speed information of the electronic device generated according to the sensed touch of the electronic device. The electronic device may be an input device including a mouse. The input information acquisition unit 120 is equipped with an optical sensor for measuring the rotation speed of the wheel configured in the mouse, and recognizes the wheel rotation speed at which the rotation shaft rotates by recognizing the surface pattern of the wheel rotation shaft through the attached optical sensor, As a touch is sensed by the user on the wheel configured in the mouse, a change in capacitance of the copper tape attached to the wheel configured in the mouse is recognized to detect whether touch including touch-up or touch-down is sensed.

In operation 230 , the scroll controller 130 may control the scroll state of the electronic device based on the obtained input information. The scroll control unit 130 detects that the wheel of the electronic device is stopped based on a metric measured by the user on the wheel of the electronic device or that the wheel of the electronic device is stopped, and thus the virtual wheel rotation calculated using the current scroll speed of the electronic device You can control the flick state to keep scrolling according to the speed. The scroll controller 130 may calculate a virtual wheel rotation speed based on a virtual wheel rotation speed deceleration algorithm using the current scroll speed of the electronic device. In this case, the virtual wheel rotation speed deceleration algorithm is a linear algorithm in which the virtual wheel rotation speed is constantly reduced with the passage of time, an exponential algorithm in which the virtual wheel rotation speed decreases in an exponential function form with the passage of time, the screen It may include any one of the virtual wheel rotation speed algorithms implemented by a method such as a content-based algorithm that adjusts the virtual wheel rotation speed according to the amount of content displayed on the screen.

The scroll control unit 130 activates a scroll function including a dormant state, a scroll state, or a flick state through a method of controlling a scroll state using a speed threshold value or a method of controlling a scroll state without using a scroll threshold value. can At this time, the deceleration algorithm may be operated using the wheel rotation speed (Scroll Velocity) and whether the wheel is touched (TOUCH_DOWN or TOUCH_UP) information. The scroll control unit 130 detects a touch on the wheel of the electronic device from the user, recognizes it as a touch-down signal, operates the electronic device in a scroll state, and the current scroll speed in the scroll state of the operated electronic device As the screen scroll speed and the screen scroll speed are mapped at a certain ratio, screen scrolling is generated in response to the current scroll speed, and when the user's finger is removed from the wheel of the electronic device in the scrolling state of the electronic device being operated, touch-up (touch-up) is detected. -up), the wheel of the electronic device can be stopped within a preset time by recognizing it as a signal. In the scrolling state of the electronic device, when the current scroll speed of the electronic device exceeds the speed threshold value based on the speed threshold value, the scroll control unit 130 determines a flick state to display the screen based on the current scroll speed of the electronic device. You can control scrolling. In the scrolling state of the electronic device, the scroll control unit 130 determines a flick state as the user senses that the wheel of the electronic device is metered by the user. may be rapidly reduced, and as the current scroll speed of the electronic device is greater than a preset reference, the scroll speed of the screen may be decreased slowly.

In the embodiment, the inertia of the scroll speed of the electronic device can be adjusted by adding inexpensive hardware devices and software without fatigue of repeated wheel scrolling. For example, the scroll control system may be configured in hardware and software inside the electronic device to control the scroll state. To this end, it is possible to measure the physical rotation speed of the scroll wheel and whether to touch it, and control the scroll speed in software by using this.

As an input for manipulating inertia in the electronic device, the physical rotation speed of the wheel and whether or not it is touched may be measured. The electronic device may be a rotatable input device, and may include, for example, a mouse, a smart watch, a crown, a trackball mouse, a dial, and the like. Hereinafter, a mouse among the input devices will be described as an example.

The mouse is an input for manipulating inertia, and it is possible to measure the physical rotation speed of the wheel configured in the mouse and whether it is touched. Referring to FIG. 3 , an optical sensor for measuring the rotation speed of the wheel may be attached to the mouse. An optical sensor facing in the direction of the arrow may be installed at a starting position of the arrow indicated on the optical sensor circuit. The optical sensor may recognize the speed at which the rotation shaft rotates by recognizing the surface pattern of the rotation shaft of the mouse wheel located in the direction of the arrow. In this case, a rotation axis may be set in the optical sensor. The optical sensor can measure the wheel rotation speed more accurately and more precisely than the wheel rotation speed transmitted by the mouse, and transmit the measured wheel rotation speed to the mouse's software.

Copper tape may be attached to the mouse wheel in order to recognize whether a touch is made through the wheel configured in the mouse. To fix the copper tape, a thin piece of rubber less than the elastic preset standard may be used, or the wheel surface may be made of a conductive material. The conductive wheel surface can be connected with a small wire to copper tape wrapped around the axle of the wheel configured on the mouse. The copper tape wrapped around the shaft can be connected to the circuit using a very low friction brush. As the user touches the wheel, the capacitance of the copper tape changes, and the changed capacitance can be recognized and transmitted to the software of the mouse. At this time, the electric capacity is a certain threshold value (

), it is determined as a touch-down state, and when the electric capacity does not exceed a predetermined threshold value, it may be determined as a touch-up state. The hardware for measuring wheel rotation speed and touch can be easily installed inside an existing mouse, and it is economical because it uses a small circuit with a simple circuit complexity.

The scroll control system will describe the operation of detecting and executing the flick state of the wheel configured in the mouse. The scroll control system may determine a scroll state of the wheel including an idle state, a scroll state, and a flick state. If the user releases the hand while rotating the mouse wheel at a speed greater than or equal to the threshold speed with a hand (finger), the inertial scroll function may be activated in the mouse. An algorithm for determining the scroll state of the wheel by using the wheel rotation speed (Scroll Velocity) and whether the wheel is touched (touch-down or touch-down) may be operated.

In order to describe the scroll state of FIG. 4 , reference will be made to input information including whether touch is sensed and speed information (rotation speed) of the wheel of FIG. 6 . The scroll control system may determine that the user is in a dormant state when the wheel configured in the mouse is not manipulated by the user and the user interface (UI) is not scrolled ( 410 ). Here, the user interface may mean a screen/screen on which a mouse is displayed in the embodiment. The dormant state may mean a state in which the user does not operate the wheel or the user's finger does not touch the wheel.

In the dormant state, the scroll control system may determine the scroll state as a state in which the user touches the mouse wheel (touch-down) is recognized ( 420 ). The scroll state in which a finger is touched may refer to a state in which wheel movement and scrolling of the user interface are mapped at a predetermined ratio. This is the same as the wheel operation of a normal mouse. In the scrolling state, scrolling may occur on the screen in response to a current scroll velocity. In this case, the current scroll speed and the screen screen speed may be mapped at a constant ratio. In the scrolling state, when the user releases a finger from the mouse wheel, a touch-up signal is generated and the wheel can stop within a short time. For example, friction between the wheel and the area around the wheel may cause the wheel to stop in a short period of time. In this case, it may be switched to one of two states including a dormant state and a flick state according to the current scroll speed.

In the scrolling state, the scroll control system may determine the current scroll speed of the mouse wheel as the user reaches a state (touch-up) measured by the user's mouse wheel ( 430 ). The touch-up, which is a metered state on the mouse wheel, means a state in which the wheel and the finger are separated. The scroll control system may determine whether the current scroll speed of the mouse wheel is 0 when the touch-up signal is generated. When the current scroll speed of the mouse wheel is not 0, the scroll control system may determine the flick state ( 440 ), and when the current scroll speed of the mouse wheel is 0 , determine the dormant state ( 410 ). In other words, the current scroll speed of the mouse wheel is

), it may be converted to a dormant state, and if the current scroll speed of the mouse wheel exceeds a speed threshold value, it may be converted to a flick state. In the idle state, the scrolling on the screen is also stopped because the wheel is stopped. In this case, FIG. 4 shows a case in which the speed threshold value is set to 0, and the speed threshold value may be set to a value other than 0 according to a user or situation. The flick state may mean a state in which the user interface (screen) continues to scroll naturally due to inertia even when the actual mouse wheel stops.

The scroll control system can determine the scroll state when the mouse wheel is in a touch-down state in the flick state (420), and when the mouse wheel speed is updated in the flick state, determine the current scroll speed of the mouse wheel again can (450). In other words, the updated mouse wheel speed may mean that the scroll speed is newly calculated and updated according to the implemented deceleration algorithm. When the current scroll speed is 0, the scroll control system may determine the dormant state ( 410 ), and when the current scroll speed is not 0 , determine the flick state ( 440 ).

It has been described that the scroll state is determined using the speed threshold in FIG. 4 . Also, the scroll state can be determined without using the speed threshold value. Previously, to determine whether the next state will be a dormant state or a flick state when the user releases the hand from the scroll state, check whether the last wheel rotation speed, that is, the current wheel rotation speed, exceeds the speed threshold value. did Alternatively, the interaction can be designed using only the last wheel rotation speed without using the speed threshold value. In a method that does not use a speed threshold, it is always in flick mode when the hand is released, which is equivalent to a threshold value of 0. In such a flick mode, the screen scroll speed is gradually decreased. As the last wheel rotation speed is smaller, the alpha value is set to a larger number, so that the screen scroll speed may be rapidly reduced. As the last wheel rotation speed decreases, the alpha value increases, and when the last wheel rotation speed is smaller than a preset reference, the operation may be similarly performed as in a dormant state. In addition, as the last wheel rotation speed increases, the scroll speed is set to a number having a small alpha value, so that the screen scroll speed is slowly decreased, thereby increasing the flick effect. The advantage of the method that does not use the speed threshold is that it can implement a state change in which the flick effect gradually increases compared to the method of switching the scroll state such as the dormant state or the flick state based on the speed threshold value. You can learn and use the interaction comfortably without considering it.

The scroll control system may execute a flick algorithm in a flick state. Referring to FIG. 7 , even when the actual wheel is stopped, the flick algorithm calculates a virtual wheel rotation speed using the current scroll speed with a software setting algorithm, and based on the calculated virtual wheel rotation speed, Scrolling of the screen may be continued. The initial value of the virtual wheel rotation speed is the current scroll speed, and the scroll speed may be gradually reduced based on a preset setting value. In this case, the wheel rotation speed deceleration algorithm may be implemented as a linear function, a function without deceleration, an exponential function, or the like in order to decelerate the scroll speed.

Referring to FIGS. 8 and 9 , when there are many characters on the screen, a content-based algorithm that scrolls more slowly may be implemented. When the virtual wheel rotation speed becomes 0 while decelerating, screen scrolling stops and it goes into a dormant state. If the user touches down the wheel before the virtual wheel rotation speed becomes 0, the flick state is stopped and the screen becomes scrollable again in proportion to the user's wheel manipulation amount. The scroll control system can manipulate the scroll state of the mouse wheel with virtual wheel rotation speed reduction software. When an inertial rotation mouse wheel is manufactured using an actual physical device, the deceleration algorithm cannot be used in various ways because the rotation speed of the actual wheel cannot be varied. In the embodiment, a user's preferred algorithm or a content-based algorithm may be used as the virtual wheel rotation speed algorithm.

As an example, a linear algorithm will be described. As time t passes, the virtual wheel rotation speed may be reduced at a constant rate (a).

Alternatively, a constant value may be decreased. If a=0, the algorithm does not decelerate. In this case, the screen may continue to scroll at the last wheel speed until the user touches the wheel.

As another example, an exponential algorithm will be described. As time t passes, the virtual wheel rotation speed may be reduced in the form of an exponential function.

In this case, since the virtual wheel rotation speed is not exactly 0, it is approximated to 0 if it is less than a certain value. In the exponential algorithm, the virtual wheel rotation speed is rapidly reduced at the beginning compared to the linear algorithm. Conversely, if the 2-exp(t) function is used instead of exp(-t), an algorithm that decreases slowly at the beginning and then decreases rapidly may be used.

As another example, a content-based algorithm will be described. It takes a lot of time for the user to scan the screen while the content is displayed on the screen by more than a preset standard. By applying this, it is possible to create an algorithm that scrolls slowly when content is displayed on the screen higher than a preset standard, and scrolls quickly when content is displayed on the screen less than a preset standard. For example, it may scroll slowly while there is a lot of content on the screen, and quickly when there is little content on the screen. In other words, the scroll speed may be controlled according to the ratio, range, or density occupied by content (eg, text data) on the screen. If the amount of text currently displayed on the screen is C and the amount of text at the slowest scrolling time is maxC, it can be configured as follows.

In this case, the function uses a linear proportional function for the amount of text, but an exponential function or a log function can be applied.

In the embodiment, a mouse wheel operation for more natural and efficient scrolling will be described using touch sensing and wheel rotation information (rotation amount, rotation speed, etc.) like a flick gesture in a mobile environment.

The first graph (upper graph) of FIG. 5 shows a case in which the user quickly rotates the wheel but does not release their hand, and the second graph (lower graph) shows a case in which the user quickly rotates the wheel and releases the hand to execute a flick will be. In these two cases, the wheel rotation speed graphs can be very similar. By analyzing the rotation speed graph, it can be determined whether the hand is released or not, but at the time of determination, the speed of the wheel may have already decreased to some extent. In order to apply the flick at the right time, you need to know immediately that the hand has fallen the moment it is released. If you detect and figure out a speed change, you can't give the user a flick state because the screen scrolling is already slowing down.

A scroll control system according to an embodiment may increase usability of a mouse wheel. While the prior art has a problem of accumulating physical fatigue when the user rotates the wheel several times in succession to scan a long list or document, in the embodiment, the mouse wheel rotates continuously with inertia through touch sensing. In operation, the user does not have to laboriously rotate the wheel several times. In addition, it is difficult to rotate the wheel repeatedly at a constant speed. According to the embodiment, because the wheel has inertia, the document can be scrolled at the same speed for a long time or the scroll speed can be controlled according to the user's preferred deceleration model. do.

According to an embodiment, by adding a touch sensing function and high-resolution rotation amount measurement to the existing mouse wheel, flick scrolling can be performed using the mouse wheel. A configuration in which a capacitive sensor and an optical sensor are added for touch sensing function and high-resolution rotational amount measurement was presented. Here, the capacitive sensor is attached to the surface of the mouse wheel to detect when a finger touches and leaves the wheel, and the optical sensor detects the rotation amount by recognizing the axis of the wheel. E, by dividing the amount of rotation of the mouse wheel by the time taken to rotate that much, the rotation speed required for the inertia model can be obtained. According to the embodiment, it is expected that the scrolling operation can be used faster and more conveniently than in the prior art, and it is expected to be a scrolling method with high ease of learning.
