Description

  The present invention relates to an information processing apparatus, an information processing method, and a program.

  Devices that allow a user to input information directly on a display screen with a finger or a pen include a tablet terminal. This tablet terminal is equipped with a device called a touch panel in the display unit, thereby enabling input of information with a finger or a pen. The touch panel is a sensor that detects the position of a finger or pen that touches the touch panel and gives an instruction to the tablet terminal by integrating a position detection sensor or the like with the display unit. In recent years, tablet terminals having a touch panel that combines two functions of display and input are rapidly spreading.

  There are various types of touch panels provided in the display unit of the tablet terminal. A resistive film method that detects the position of the screen pressed with a finger or pen by measuring the voltage change, or a weak current generated when you touch the screen with your finger, that is, a change in capacitance (charge) is detected by the sensor, The main method is a capacitance method for grasping the touched position. In recent years, as in Patent Document 1, a tablet terminal is provided with a vibration actuator, and a technique of giving vibration (haptic) by a user touching the touch panel has also been released. Development is progressing.

  Since the tablet terminal is lighter and more compact than a notebook personal computer, it can be easily used outdoors. Under such circumstances, there is an increasing need for a tablet terminal that can realize a certain operability in any place. The tablet terminal detects a position where the sensor is applied by applying force to the screen with a finger or a pen, and performs predetermined processing. For example, in a train or the like, the user applies force to the screen with a finger or a pen in an unstable place such as on the knee. In such an unstable situation, the tablet terminal moves when the user applies a force with a finger or a pen, which is very difficult to operate.

  Based on such a situation, a technique is disclosed that allows a user to change an output value output based on a pressure applied to the screen of the tablet terminal according to the situation. In other words, the pressure applied to the screen in an unstable situation such as on the user's knee and the pressure applied to the screen in a stable situation such as placement are different output values even at the same pressure, so depending on the situation Improved operability can be expected.

  However, the change of the output value based on the pressure applied to the screen of the tablet terminal so far had to be performed by the user himself on the screen. Since the user himself / herself determines a stable situation and an unstable situation and performs a change procedure, there is a problem that the burden on the user is heavy.

  Hereinafter, embodiments of the present invention will be described in detail.

  First, the configuration of the information processing apparatus 1 according to the present embodiment will be described with reference to FIG. Note that the configuration of the information processing apparatus 1 is not necessarily the same as that shown in FIG. 1, and it is sufficient if it has hardware and functions capable of realizing the present embodiment.

  The information processing apparatus 1 includes a control unit 100 for realizing overall control of the information processing apparatus 1 by executing a predetermined program, and a display unit including a display using a panel such as liquid crystal and organic EL 110, a sensor unit 130 that detects the state of the information processing device 1, a communication I / F 150 that enables connection to a network and an external device, a program read by the information processing device 1, and various data are stored in a nonvolatile manner The storage unit 160 includes an input unit 170 configured by hardware input keys necessary for power ON / OFF and various settings, and a storage unit 180 that temporarily stores data and the like.

  The control unit 100 of the information processing apparatus 1 realizes overall control of the information processing apparatus 1 by executing a predetermined program. In conjunction with various functions constituting the information processing apparatus 1, processing is executed based on a predetermined program. The control unit 100 can be configured by a ROM, which is a read-only memory that reads various programs, and a CPU.

  The display unit 110 of the information processing apparatus 1 displays an image according to image information and a video signal supplied from the control unit 100. The information processing apparatus used in the present embodiment includes a touch panel 120 for inputting information such as characters, numbers, symbols, and the like on the display unit of the display unit based on the displayed image.

  Although not shown, a position detection sensor is coupled to the touch panel 120. By using this position detection sensor, it is possible to sense the position of a finger or pen in contact with the screen and give an instruction to the computer. The touch operation detection method includes a resistive film method that detects the position of the screen pressed with a finger or pen by measuring the voltage change, or a weak current generated when a finger touches the screen, that is, a capacitance ( There is a capacitance method in which a change in charge) is sensed by a sensor, but a touch panel employing these detection methods may be used, or other detection methods may be used.

  The sensor unit 130 of the information processing apparatus 1 includes a sensor that detects a value that serves as an index for determining the state of the information processing apparatus 1. The state here is a state where the information processing apparatus 1 is placed. Although various indicators for determining the state are assumed, in this embodiment, the acceleration sensor 140 is used to tilt the information processing apparatus 1 with respect to the horizontal line, and the degree of vibration of the information processing apparatus 1. And the control unit 100 determines the state of the information processing apparatus 1 based on the information.

  In order to detect the state of the information processing apparatus 1, it can be detected using a sensor other than the acceleration sensor. For example, a gyro sensor can be used instead of the acceleration sensor or in combination with the acceleration sensor. Or there exists a method of measuring the pressure concerning the contact surface of the member which contacts the information processing apparatus 1 directly using a pressure sensor. If a threshold value is set for such pressure and a pressure higher than a predetermined pressure is applied to the contact surface, it is determined that the pressure is stable. In addition, an optical sensor is used to detect how much the member in direct contact with the information processing apparatus 1 is in contact with the light quantity, and whether the state is stable or unstable is determined from the detection result. Although an acceleration sensor is used in this embodiment, a configuration in which the state of the information processing apparatus 1 is detected using a pressure sensor, an optical sensor, or other sensors is also possible.

  The communication I / F 150 of the information processing apparatus 1 is an interface for inputting / outputting various types of information to / from external devices and electronic devices such as computers via a network. The communication I / F 150 includes, for example, a USB port, a LAN port, a wireless LAN port, and the like. Any communication I / F 150 may be used as long as data can be transmitted / received to / from an external device.

  The storage unit 160 of the information processing apparatus 1 stores a program read by the information processing apparatus 1 and various data in a nonvolatile manner. The storage unit 160 can be constituted by, for example, a RAM used as a working memory by the control unit 100 or an HDD capable of holding various data records when the power is turned off.

  The input unit 170 of the information processing apparatus 1 includes hardware input keys necessary for power ON / OFF and various settings.

  The storage unit 180 of the information processing apparatus 1 preliminarily stores table data indicating the relationship between the data of processing performed by the control unit 100 based on a predetermined program, or in this embodiment, the state of the information processing apparatus 1 and the pressure range pattern. However, the table information may be stored. The table information will be described later. The stored data is read by the control unit 100 based on a predetermined program. Note that information provided in advance, such as table information used in the present embodiment, can be stored in the storage unit 160 instead of the storage unit 180. The storage unit 180 can be configured by a RAM or the like used by the control unit 100 as a working memory.

  Next, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 2 shows functional blocks of the information processing apparatus of this embodiment. The information processing apparatus 1 according to the present embodiment includes a sensor 10, a sorting unit 11, and a control unit 12.

  The sensor 10 of the information processing device 1 detects the state of the information processing device 1. In this embodiment, an acceleration sensor is used to detect the inclination angle of the information processing apparatus 1 with respect to the horizontal line and how much the information processing apparatus 1 is vibrating.

  The sensor 10 of the information processing apparatus 1 can be realized by the sensor unit 130.

  The sorting means 11 of the information processing apparatus 1 includes a first state in which the information processing apparatus maintains a state parallel to the horizontal line based on the output of the sensor, and the information processing apparatus in parallel to the horizontal line. It is divided into a second state that does not hold a new state. The first state is, for example, a state placed on a desk or the like, and maintains a state parallel to the horizontal line. That is, the first state can be said to be a stable state that does not move or vibrate even when pressure is applied to the touch panel from the outside.

  In the second state, for example, a part of the information processing apparatus 1 is supported by being inclined with respect to the horizontal line by a support member or the like. In addition, the second state may be a state where a person is holding by hand. Moreover, if it is in a state held by a person, it may be in a state parallel to the horizon in some cases, but it is in a state where it vibrates slightly, so it does not fall under the first state. The first state and the second state are classified according to the inclination angle of the information processing device 1 output from the sensor with respect to the horizontal line and the presence or absence of vibrations generated in the information processing device.

  The sorting unit 11 of the information processing apparatus 1 can be realized by the control unit 100 and the sensor unit 130.

  The control means 12 of the information processing apparatus 1 will explain the relationship between the pressure applied to the touch panel and the output value with reference to FIG.

  FIG. 3 is a diagram showing the relationship between the pressure applied to the touch panel and the output value according to the embodiment of the present invention. The output value here is the intensity of the signal output based on the pressure applied to the touch panel. In the present embodiment, the output value is assumed to be 128 steps, and a plurality of pressure range patterns are provided. Note that the output value can be applied not only in 128 steps but also in 256 steps and other output value steps. In the pressure range pattern A of the output value, the pressure required to obtain the output value of 128 steps that is the maximum of the output value is 1 (pa), whereas in the pressure range pattern B of the output value, the output value The pressure required to obtain the output value of 128 steps which is the maximum of the required pressure is 0.6 (pa).

  With respect to the pressure range pattern A of the output value, the pressure range pattern B of the output value can obtain a large output value with a small pressure. In this embodiment, the output value pressure range pattern A is applied to the first state, and the output value pressure range pattern B is applied to the second state. Since it can be said that the second state is unstable with respect to the first state, it is necessary to output a large output value with less pressure. Here, the unstable state is a state in which, when pressure is applied to the touch panel, the information processing apparatus 1 moves, or the information processing apparatus 1 vibrates, so that it is difficult to apply pressure.

  Next, the relationship between the state of the information processing apparatus according to the embodiment of the present invention and the pressure range of the output value will be described. FIG. 4 is a diagram for explaining the relationship between the state of the information processing apparatus according to the embodiment of the present invention and the pressure range of the output value.

  The table of FIG. 4 shows the detection result (the presence or absence of vibration, the angle formed by the information processing device and the horizontal line) by the acceleration sensor in the state pattern (first state, second state) sorted by the sorting unit 11; This corresponds to the pressure range pattern of the output value. In the state example, the possible situations are described based on the output result detected from the acceleration sensor, and therefore, this is not the case. This table is stored in the storage unit 160 or the storage unit 180, and is read out and referred to by the control unit 100 in response to an output from the acceleration sensor.

  If the output result from the acceleration sensor is “no vibration” and “the angle θ = 0 ° with the horizontal line”, it is determined that the state is the first state. The pressure range pattern of the output value at that time is set as A. Further, if the output result from the acceleration sensor is “no vibration”, “the angle θ ≠ 0 ° with the horizontal line”, or the output result from the acceleration sensor is “vibration”, it is determined to be in the second state. The In the state of “with vibration”, it is determined that the “angle θ with the horizontal line” is the second state regardless of the value.

  When it is determined that the state is the second state, the pressure range pattern of the output value is set to B.

  The control unit 12 of the information processing apparatus 1 can be realized by the control unit 100, the sensor unit 130, the storage unit 160, and the storage unit 180.

  Next, a flowchart according to the embodiment of the present invention will be described. FIG. 5 is a flowchart according to an embodiment of the present invention.

  First, it is assumed that the current state of the information processing apparatus 1 is the first state (step 1). Next, an inclination angle and a vibration state are output from the acceleration sensor (step 2). Based on the output from the acceleration sensor, the determination table is read to determine the current state of the information processing apparatus 1 (step 3). The state of the information processing apparatus 1 is confirmed, and when the state is changed from the first state (step 4), the pressure range of the output value is changed based on the determination table (step 5).

  In step 4, if the state of the information processing device 1 has not changed from the first state, it is determined that the state has not changed, and the pressure range pattern of the output value is not changed (step 6). .

  In the above, the Example which performs this embodiment with a suitable form was described. Although a specific specific example has been shown and described here, various modifications and form changes of the specific example can be made without departing from the spirit and scope of the claims.

  As an example of a change in the embodiment, a configuration that uses a pressure sensor, an electrostatic sensor, or an optical sensor instead of an acceleration sensor as a sensor that detects the state of the sensor unit 130 is possible. Further, not only one type of sensor but also a plurality of sensors are combined to define various states, and if the pressure range of the output value can be changed for each state, further improvement in usability can be expected. .

  By using various state detection sensors, variations of the stable state A and the non-stable state B can be expanded. For example, it is possible to determine whether or not the state is stable by detecting the pressure applied to the contact surface that is in contact with the information processing apparatus 1 with a pressure sensor or the like, and the information processing as described in the present embodiment is possible. It is possible to define a stable state that is not limited to the case where the device 1 is horizontal. It is possible to define elements other than the tilt state and vibration state of the information processing apparatus 1 in addition to the state stability and instability.

  According to the present invention, there is provided an information processing apparatus capable of realizing smooth touch operability by changing an output result output based on a pressure applied to a touch panel according to a state of the device according to a state of the device. can do.
