Abstract
Description
A haptic controller device that senses movement for each switch
[0001] The present invention relates to a haptic controller device that senses movement for each switch, and more specifically, to a haptic controller device that senses a pressure value applied to each switch and controls movement for each switch.
[0002] In order to enhance the sense of immersion and presence in a virtual reality environment in conjunction with virtual reality, various technologies are being researched and developed to provide natural user interface technology using both hands and haptic feedback such as tactile and kinesthetic sensations through this.
[0003] User interfaces equipped with vibration elements provide haptic feedback by modulating vibration patterns to indicate the start / end or termination of an interaction, or to indicate whether the interface has been manipulated. However, this method suffers from the difficulty of providing realistic feedback due to the lack of kinesthetic feedback.
[0004] User interfaces in the form of gloves or exoskeletons have been proposed to provide kinesthetic sensations such as grasping objects in virtual reality, applying force to hold or press them, but these cases have limitations in use due to issues such as the complexity of wearing them and the size of the external device.
[0005] Meanwhile, Korean Patent Publication No. 10-2017-0016695 (Patent Document 1) discloses “Interaction Controller, Haptic Feedback Providing System and Method Using Interaction Controller,” wherein the interaction controller comprises a sensor unit including a gyro sensor and an acceleration sensor; and a haptic unit including a plurality of haptic actuators arranged at regular intervals on a handle portion and operating according to movements detected by the sensor unit.
[0006] In the case of Patent Document 1 as described above, although it is possible to provide various spatial tactile feedback according to the movement of the interaction controller through a plurality of haptic actuators arranged in two dimensions, it only presupposes a situation in which tactile feedback is provided at the surface where the interaction controller and the user's hand (fingers and palm) come into contact, and there was a problem in that it could not properly respond to the physical displacement and kinesthetic feedback that occur in situations such as when gripping or pressing an object with force by hand.
[0007] The problem to be solved by the present invention is to provide a haptic controller device that can control movement for each switch by measuring the pressure applied to each switch.
[0008] Another object of the present invention is to provide a haptic controller device capable of controlling movement for each switch to adjust the intensity of rehabilitation exercise for each finger of a rehabilitation patient.
[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.
[0010] A haptic controller device according to the present invention comprises: a housing having an accommodation space therein; a plurality of rotary switches rotatably installed in the housing; a sensor structure having a plurality of thin plates installed on one side of the rotary switches; and at least one pressure sensor installed on one side of each of the thin plates, wherein the pressure sensor may include at least one pressure sensor that measures a pressure applied to each of the rotary switches.
[0011] Specific details of other embodiments are included in the detailed description and drawings.
[0012] According to embodiments of the present invention, the present invention can control movement of each switch by measuring the pressure applied to each switch.
[0013] By controlling the movement of each switch, the intensity of rehabilitation exercise can be adjusted for each finger of the rehabilitation patient.
[0014] Additionally, by controlling the movement of the switch according to the pressure applied to each switch, it is possible to provide precise tactile feedback to the user.

The fifth connection connector portion (3185) can be connected to the connection board (3186) while passing between the second rotation shaft (280) and the fifth side wall portion (252). Accordingly, when the second to fifth rotary switches (220, 230, 240, 250) rotate, interference of the second to fifth connecting connector parts (3182, 3183, 3184, 3185) can be minimized.
[0082]
[0083] The first pressure sensor (321) may be installed on one side of the first plate (311). One or more first pressure sensors (321) may be installed on the first plate (311). In an embodiment, two first pressure sensors (321) may be installed on the first plate (311). The first pressure sensor (321) may measure a pressure (or force) applied to the first rotary switch (210). For example, the first pressure sensor (321) may measure a first pressure value applied by a user's thumb to the first rotary switch (210). The first pressure sensor (321) may transmit the measured first pressure value to the control unit (500).
[0084] The second pressure sensor (322) may be installed on one side of the second plate (312). One or more second pressure sensors (322) may be installed on the second plate (312). The second pressure sensor (322) may measure the pressure (or force) applied to the second rotary switch (220). The second pressure sensor (322) may transmit the measured second pressure value to the control unit (500).
[0085] The third pressure sensor (323) may be installed on one side of the third plate (313). One or more third pressure sensors (323) may be installed on the third plate (313). The third pressure sensor (323) may measure the pressure (or force) applied to the third rotary switch (230). The third pressure sensor (323) may transmit the measured third pressure value to the control unit (500).
[0086] The fourth pressure sensor (324) may be installed on one side of the fourth plate (314). One or more fourth pressure sensors (324) may be installed on the fourth plate (314). The fourth pressure sensor (324) may measure the pressure (or force) applied to the fourth rotary switch (240). The fourth pressure sensor (324) may transmit the measured fourth pressure value to the control unit (500).
[0087] The fifth pressure sensor (325) may be installed on one side of the fifth plate (315). One or more fifth pressure sensors (325) may be installed on the fifth plate (315). The fifth pressure sensor (325) may measure the pressure (or force) applied to the fifth rotary switch (250). The fifth pressure sensor (325) may transmit the measured fifth pressure value to the control unit (500).
[0088] In the embodiment, each of the first to fifth pressure sensors (321, 322, 323, 324, 325) may be a force sensitive resistor (FSR) whose resistance value changes depending on physical force, weight, etc., but is not limited thereto.
[0089] In an embodiment, three of the second to fifth pressure sensors (322, 323, 324, 325) may be installed on each of the second to fifth plates (312, 313, 314, 315). The number of the second to fifth pressure sensors (322, 323, 324, 325) installed on each of the second to fifth plates (312, 313, 314, 315) may be greater than the number of the first pressure sensors (321) installed on the first plate (311). For example, three of the second to fifth pressure sensors (325) may be installed on each of the second to fifth plates (312, 313, 314, 315). This allows an external force of the thumb to act on the first plate (311). This is because the contact area between the thumb and the first rotary switch (210) is smaller than the contact area between the other fingers and the second to fifth rotary switches (220, 230, 240, 250). Therefore, the number of first pressure sensors (321) installed on the first plate (311) can be reduced, thereby lowering the production cost.
[0090] The button sensor (326) may be installed on the first button-type switch (260). The button sensor (326) may be a motion sensor capable of measuring the position and posture of the user's hand, but is not limited thereto. In an embodiment, the button sensor (326) may include an IMU (Inertial Measurement Unit) as a sensor for detecting the position and posture of the housing (100). Information measured by the button sensor (326) may be transmitted to the control unit (500).
[0091] The actuator unit (400) can be installed within the housing (100). The actuator unit (400) is connected to the other side of the first to fifth rotary switches (210, 220, 230, 240, 250) so as to individually rotate the first to fifth rotary switches (210, 220, 230, 240, 250). Accordingly, the actuator unit (400) can independently rotate each of the first to fifth rotary switches (210, 220, 230, 240, 250) without interference from other rotary switches.
[0092] In an embodiment, the actuator unit (400) can pull the first to fifth rotary switches (210, 220, 230, 240, 250). Accordingly, the actuator unit (400) can rotate the first to fifth rotary switches (210, 220, 230, 240, 250) by providing an external force in the same direction as the rotational direction of the first to fifth rotary switches (210, 220, 230, 240, 250).
[0093] In addition, the actuator unit (400) can push the first to fifth rotary switches (210, 220, 230, 240, 250). Accordingly, the actuator unit (400) can rotate the first to fifth rotary switches (210, 220, 230, 240, 250) by providing an external force in a direction opposite to the rotational direction of the first to fifth rotary switches (210, 220, 230, 240, 250). By the actuator unit (400) providing an external force in a direction opposite to the rotational direction of the first to fifth rotary switches (210, 220, 230, 240, 250), the haptic controller device (10) can provide a tactile feedback to the user, thereby providing a tactile sensation of touching an object with the hand in virtual reality.
[0094] The actuator unit (400) may include a first driving unit, a second driving unit (402), a third driving unit (403), a fourth driving unit (404), and a fifth driving unit (405).
[0095] The first driving unit is connected to the first rotary switch (210) and can rotate the first rotary switch (210). The second driving unit (402) is connected to the second rotary switch (220) and can rotate the second rotary switch (220). The third driving unit (403) is connected to the third rotary switch (230) and can rotate the third rotary switch (230). The fourth driving unit (404) is connected to the fourth rotary switch (240) and can rotate the fourth rotary switch (240). The fifth driving unit (405) is connected to the fifth rotary switch (250) and can rotate the fifth rotary switch (250).
[0096] Each of the first to fifth drive units (402, 403, 404, 405) may include a case (410), a screw member (430), a rotational power unit (450), a sliding member (420), a gear unit (440), and a displacement sensor (not shown). In an embodiment, the case (410) of each of the first to fifth drive units (402, 403, 404, 405) may be formed as one. Alternatively, in another embodiment, the case (410) of each of the first to fifth drive units (402, 403, 404, 405) may be individually separated.
[0097] The case (410) may have a space therein for accommodating components such as a screw member (430) and a rotational power unit (450). The case (410) may include a sliding hole through which a sliding member (420) passes, facing the first opening (O1) or the second opening (O2) of the housing (100).
[0098] The rotational power unit (450) may be installed within the case (410). The rotational power unit (450) may generate rotational power. In an embodiment, the rotational power unit (450) may be an electric motor, but is not limited thereto. The rotational power unit (450) may be driven in response to a control signal from the control unit (500). Accordingly, the control unit (500) may control the rotational power of the rotational power unit (450).
[0099] The sliding member (420) may be installed on one side of each of the rotary switches. The sliding member (420) may be formed in the shape of a bar or rod that is elongated in one direction. The sliding member (420) may have an insertion groove (423) on the other side thereof into which a screw member (430) is inserted. Screw threads may be formed on the inner surface of the insertion groove (423).
[0100] One side of the sliding member (420) can be fastened to the first fastening guide part, the second fastening guide part (223), etc., as described above. As illustrated in Fig. 17, the sliding member (420) can include an insertion hole (425) on one side into which any one of the first to fifth fastening members (224, 234, 244, 254) is inserted.
[0101] The sliding member (420) can move linearly by the rotational power of the rotational power unit (450). Accordingly, the sliding member (420) can provide an external force that pushes or pulls each of the rotary switches.
[0102] The screw member (430) may be positioned within the case (410). The screw member (430) may be formed to be elongated in one direction. In an embodiment, the screw member (430) may be positioned on the same line as the sliding member (420). The screw member (430) may be formed in a circular rod shape. The screw member (430) may be rotated by the rotational power of the rotational power unit (450).
[0103] The screw member (430) can be inserted into the insertion groove (423) of the sliding member (420). The screw member (430) can have screw threads formed on the outer surface thereof that engage with the screw threads of the insertion groove (423). Accordingly, when the screw member (430) is rotated by the rotational power unit (450), the sliding member (420) can move linearly along the longitudinal direction of the screw member (430). In other words, the screw member (430) can move the sliding member (420) linearly by being rotated by the rotational power unit (450). The gear unit (440) can control the rotational power of the rotational power unit (450).
[0104] A displacement sensor may be installed within the case (410). The displacement sensor may be positioned adjacent to the sliding member (420). The displacement sensor may measure the displacement of the linearly moving sliding member (420). Displacement information measured by the displacement sensor may be transmitted to the control unit (500).
[0105] The control unit (500) may be installed within the housing (100). The control unit (500) may be electrically connected to the sensor structure (310). Accordingly, the control unit (500) may receive information measured by the first to fifth pressure sensors (321, 322, 323, 324, 325). In addition, the control unit (500) may receive information measured by the displacement sensors of the first to fifth driving units (402, 403, 404, 405) described above.
[0106] The control unit (500) may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), or an ARM processor, or may be defined by the terms thereof. In addition, the control unit (500) may be implemented as a system on chip (SoC) or large scale integration (LSI) having a built-in processing algorithm, or may be implemented in the form of an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA).
[0107] The control unit (500) can control the actuator unit (400) using the first to third pressure values measured by the first to fifth pressure sensors (321, 322, 323, 324, 325). In an embodiment, the control unit (500) can control the rotational power unit (450) of the first drive unit using the first pressure value. The control unit (500) can receive a plurality of first pressure values measured by the plurality of first pressure sensors (321). The control unit (500) can control the actuator unit (400) (first drive unit) to rotate the first rotary switch (210) using the largest pressure value among the plurality of first pressure values.
[0108] Alternatively, in another embodiment, the control unit (500) may calculate an average value of a plurality of first pressure values. The control unit (500) may control the actuator unit (400) (first drive unit) to rotate the first rotary switch using the average value of the first pressure values.
[0109] The control unit (500) can control the rotational power unit (450) of the second drive unit (402) using the second pressure value. The control unit (500) can receive a plurality of second pressure values measured by a plurality of second pressure sensors (322). The control unit (500) can control the actuator unit (400) (second drive unit (402)) to rotate the second rotary switch (220) using the largest pressure value among the plurality of second pressure values.
[0110] Alternatively, in another embodiment, the control unit (500) may calculate an average value of a plurality of second pressure values. The control unit (500) may control the actuator unit (400) (second drive unit) to rotate the second rotary switch using the average value of the second pressure values.
[0111] The control unit (500) can control the rotational power unit (450) of each of the third to fifth drive units (403, 404, 405) using the third to fifth pressure values. The method by which the control unit (500) controls the third to fifth drive units (403, 404, 405) can be the same as the method by which the control unit (500) controls the first drive unit or the second drive unit (402).
[0112] In an embodiment, when first to fifth pressure values are input, the control unit (500) can calculate displacement values corresponding to the first to fifth pressure values. Each of the displacement values may be a value corresponding to the position of the sliding member (420) of each of the first to fifth driving units (402, 403, 404, 405).
[0113] For example, when a user grips the second rotary switch (220) using an index finger, the second pressure values of the index finger measured by each of the second pressure sensors (322) can be transmitted to the control unit (500).
[0114] The control unit (500) can calculate a second displacement value corresponding to the position of the sliding member (420) of the second driving unit (402) using the largest value among the second pressure values. As a method of calculating the second displacement value, the second displacement value corresponding to the second pressure value can be calculated from data table information that calculates the relationship between the pressure value and the displacement value.
[0115] The control unit (500) can control the rotational power unit (450) of the second driving unit (402) so that the sliding member (420) of the second driving unit (402) linearly moves to a position corresponding to the second displacement value. Accordingly, the sliding member (420) can pull the second rotary switch (220) while moving to a position corresponding to the second displacement value. Accordingly, the second rotary switch (220) can rotate at a certain angle. In addition, as the second rotary switch (220) rotates at a certain angle, the user can receive a repulsive force at a position where the second rotary switch (220) stops rotating and a position where the linear movement of the sliding member (420) of the second driving unit (402) stops. Accordingly, the user can feel a feedback feedback.
[0116] In this way, the control unit (500) can control the exercise intensity of the user's finger movement by controlling the actuator unit (400). In an embodiment, the control unit (500) can control the actuator unit (400) so as to provide the user with feedback inversely proportional to the pressure value measured by the pressure sensors.
[0117] The control unit (500) can obtain displacement information of the sliding member (420) from the displacement sensors of each of the first to fifth driving units (402, 403, 404, 405) and compare the calculated displacement values with the measured displacement values. If a difference occurs between the calculated displacement values and the measured displacement values, the control unit (500) can control the actuator unit (400) to correct the position of the sliding member (420). The control unit (500) can transmit motion information, pressure values, etc. measured by the motion sensor unit (300) to the outside through the communication unit (700).
[0118] The communication unit (700) may be installed in the housing (100). The communication unit (700) may perform wireless communication with an external device (e.g., a mobile phone, a computer, etc.). The communication unit (700) may transmit motion information, pressure values, etc. input from the control unit (500) to the external device. In addition, the communication unit (700) may receive various types of information from the external device. In an embodiment, the communication unit (700) may be a wireless communication module such as Wi-Fi, LTE, Bluetooth, etc.
[0119] The battery unit (600) may be installed within the housing (100). The battery unit (600) may store power supplied from an external source. The battery unit (600) may supply power to electronic components such as the actuator unit (400), the control unit (500), and the motion sensor unit (300). The battery unit (600) may be connected to a charging terminal. Accordingly, the battery unit (600) may receive external power from the charging terminal and store electricity.
[0120] The operation of the haptic controller device (10) according to the present invention configured as described above is described as follows.
[0121] A user can hold the haptic controller device (10) with his / her hand. Accordingly, the thumb can press the first rotary switch (210), the index finger can press the second rotary switch (220), the middle finger can press the third rotary switch (230), the ring finger can press the fourth rotary switch (240), and the little finger can press the fifth rotary switch (250).
[0122] The first to fifth pressure sensors (321, 322, 323, 324, 325) installed in the first to fifth rotary switches (250) can measure the pressure applied by the user's finger. Accordingly, the first to fifth pressure sensors (321, 322, 323, 324, 325) can transmit the first to fifth pressure values to the control unit (500).
[0123] The control unit (500) can control the actuator unit (400) using each of the first to fifth pressure values. In other words, each of the first to fifth drive units (402, 403, 404, 405) corresponding to the first to fifth pressure values can be controlled. Accordingly, each of the first to fifth drive units (402, 403, 404, 405) can pull the first to fifth rotary switches (210, 220, 230, 240, 250) corresponding to each of the first to fifth pressure values.
[0124] As the first to fifth driving units (402, 403, 404, 405) pull the first to fifth rotary switches (210, 220, 230, 240, 250), the first to fifth rotary switches (210, 220, 230, 240, 250) can rotate at a certain angle. Accordingly, the user can feel the sensation of grasping an object. In addition, as the first to fifth rotary switches (210, 220, 230, 240, 250) rotate only by a certain angle, the user can feel a repulsive force at the point where the rotation of the first to fifth rotary switches (210, 220, 230, 240, 250) stops. Accordingly, the user can feel a feedback.
[0125] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by a person skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be understood individually from the technical idea or prospect of the present invention.
