Summary of the Invention

Problems to be Solved by the Invention

[0005] The main purpose of measuring and evaluating study time is to motivate children or the like who are studying. The method of changing the displayed image according to the amount of writing, as in the inventions described in Patent Documents 1 and 2, is effective.

[0006] However, depending on the content being studied, the study time and the amount of note-taking do not always match. For example, in the case of writing Chinese characters, the amount of note-taking is important, but in the case of word problems in arithmetic, time is required to think in one's head while stopping the pen or hand before filling in the answer. Therefore, it is necessary to properly evaluate the time other than the note-taking action as study time as well.

[0007] The present invention solves the above-described conventional problems, and provides a study time measurement device and a study time measurement method capable of properly evaluating not only the note-taking action but also the time other than the note-taking action as study time.

Means for Solving the Problems

[0008] To solve the above problems, the study time measurement device of the present invention includes a note-taking action detection means for detecting a note-taking action, a study start determination means for determining that study has started when the note-taking action detection means detects a note-taking action, a study end determination means for determining that study has ended when the time during which the note-taking action detection means does not detect a note-taking action reaches a predetermined time or more, and a study time calculation means for calculating, as the study time, the time obtained by subtracting the predetermined time from the time from the study start determination by the study start determination means to the study end determination by the study end determination means.

[0009] Also preferably, it has a reference state registration means for registering a reference state before the note-taking action, and the note-taking action detection means detects a note-taking action based on a change from the reference state.

[0010] Also preferably, the study time calculation means sets the study time to 0 when the calculated study time is equal to or less than a predetermined minimum time.

[0011] In addition, the study time measurement method of the present invention includes a writing motion detection step for detecting a writing motion, a study start determination step for determining that study has started when a writing motion is detected in the writing motion detection step, a study end determination step for determining that study has ended when the time during which no writing motion is detected in the writing motion detection step reaches a predetermined time or more, and a study time calculation step for calculating, as the study time, the time obtained by subtracting the predetermined time from the time from the study start determination in the study start determination step to the study end determination in the study end determination step. It is characterized by having these steps.

Effect of the Invention

[0012] The study time measurement device of the present invention has a writing motion detection means, a study start determination means, a study end determination means, and a study time calculation means. When the writing motion detection means detects a writing motion, the study start determination means determines that study has started. When the time during which the writing motion detection means does not detect a writing motion reaches a predetermined time or more, the study end determination means determines that study has ended. The study time calculation means calculates, as the study time, the time obtained by subtracting the predetermined time from the time from the study start determination to the study end determination. That is, when the time during which no writing motion is detected continues, if it is less than the predetermined time, it is included in the study time, and if it is the predetermined time or more, it is excluded from the study time. Therefore, not only the writing motion but also the time other than the writing motion can be properly evaluated as the study time.

[0013] In addition, if it has a reference state registration means for registering the reference state before the writing motion, and the writing motion detection means detects the writing motion based on the change from the reference state, the writing motion can be accurately detected even if the reference state varies depending on the user.

[0014] In addition, if the study time calculated by the study time calculation means is set to 0 when it is less than a predetermined minimum time, it is possible to exclude a time that is too short to be evaluated as the study time.

[0015] The study time measurement method of the present invention has a note-taking action detection step, a study start determination step, a study end determination step, and a study time calculation step. When a note-taking action is detected in the note-taking action detection step, it is determined that study has started in the study start determination step. When the time during which no note-taking action is detected in the note-taking action detection step reaches a predetermined time or more, it is determined that study has ended in the study end determination step. In the study time calculation step, the time obtained by subtracting a predetermined time from the time from the study start determination to the study end determination is calculated as the study time. That is, when the time during which no note-taking action is detected continues, if it is less than the predetermined time, it is included in the study time, and if it is equal to or more than the predetermined time, it is excluded from the study time. Therefore, not only the note-taking action but also the time other than the note-taking action can be properly evaluated as the study time.

[0016] As described above, according to the present invention, it is possible to provide a study time measurement device and a study time measurement method capable of properly evaluating not only the note-taking action but also the time other than the note-taking action as the study time.

Modes for Carrying Out the Invention

[0018] Next, with reference to FIGS. 1 to 5, a study time measurement device and a study time measurement method according to an embodiment of the present invention will be described. The study time measurement device and the study time measurement method according to the present embodiment are for properly measuring and evaluating the study time of a child or the like who is studying (hereinafter referred to as "user") and for arousing the motivation of the user.

[0019] FIG. 1 is a diagram showing the usage state of the study time measurement device 10 according to the present embodiment. The study time measurement device 10 is a band-type device worn on the wrist of the dominant arm of a user holding a writing instrument 1.

[0020] The study time measurement device 10 is provided with a three-axis acceleration sensor, a microcomputer-mounted module having a communication function, an EEPROM, and a full-color LED, and realizes each means (see FIG. 2) described later.

[0021] The study time measurement device 10 is wirelessly connected to a terminal 20 such as a smartphone. The connection method can be, for example, Bluetooth (registered trademark), but may also be a wireless LAN or the like, or a wired connection.

[0022] The terminal 20 is provided with an application for operating the study time measurement device 10, and the user operates the study time measurement device 10 by means of the application on the terminal 20. Note that operation buttons or the like can also be provided on the study time measurement device 10 side. Further, the study time data measured by the study time measurement device 10 is transmitted to the terminal 20.

[0023] Next, the functions of the study time measurement device 10 will be described. FIG. 2 is a configuration diagram of the study time measurement device. The study time measurement device 10 has a writing operation detection means 11, a study start determination means 12, a study end determination means 13, a study time calculation means 14, and a reference state registration means 15.

[0024] The writing operation detection means 11 detects the writing operation of the user and is realized by a three-axis acceleration sensor. The three-axis acceleration sensor can detect the direction and minute vibration of the user's hand (arm), and detects the writing operation based on the change from the reference state described later.

[0025] When the writing motion detection means 11 detects a writing motion, the study start determination means 12 determines that the user has started studying. The information on the study start determination by the study start determination means 12 is transmitted to the study time calculation means 14.

[0026] When the time during which the writing motion detection means 11 does not detect a writing motion becomes equal to or longer than a predetermined time, the study end determination means 13 determines that the study has ended. The information on the study end determination by the study end determination means 13 is transmitted to the study time calculation means 14. The predetermined time is determined in advance and can be set to any time, for example, it can be set to 10 minutes.

[0027] The study time calculation means 14 calculates the study time as the time obtained by subtracting a predetermined time determined in advance from the time from the study start determination by the study start determination means 12 to the study end determination by the study end determination means 13. In addition, when the calculated study time is equal to or less than a predetermined minimum time (for example, 1 minute), the study time calculation means 14 can set the study time to 0.

[0028] The reference state registration means 15 registers the reference state before the user's writing motion. The writing motion detection means 11 detects a writing motion based on a change from the registered reference state.

[0029] Next, a method for measuring the study time by the study time measuring device 10 will be described. FIG. 3 is a flowchart of reference state registration, and FIG. 4 is a flowchart of study time measurement.

[0030] First, as shown in FIG. 3, the user wearing the study time measuring device 10 holds a writing instrument and remains stationary in the usual writing posture with the writing tip touching the paper (step S101), and taps the recording start button displayed on the terminal 20.

[0031] The reference state registration means 15 acquires data in a stationary state from the note-taking operation detection means 11 (3-axis acceleration sensor) (step S102) and registers it as data in the reference state (step S103). When the registration is completed, the LED of the study time measurement device 10 may be lit to give a signal. As described above, data in the reference state before the user's note-taking operation is registered in the study time measurement device 10, and the preparation for measuring the study time is completed.

[0032] Next, as shown in FIG. 4, the note-taking operation detection means 11 acquires data from the 3-axis acceleration sensor in order to detect the user's note-taking operation (step S201). As a result of the data acquisition, when a note-taking operation is detected due to a change from the reference state (step S202 Yes), the study start determination means 12 determines that the study has started (step S203) and transmits information on the study start determination to the study time calculation means 14. When a note-taking operation is not detected (step S202 No), the note-taking operation detection means 11 repeats the data acquisition.

[0033] Subsequently, the note-taking operation detection means 11 acquires data from the 3-axis acceleration sensor in order to detect the user's note-taking operation (step S204). When a predetermined time has elapsed without detecting the user's note-taking operation (step S205 Yes), the study end determination means 13 determines that the study has ended (step S206) and transmits information on the study end determination to the study time calculation means 14. When a note-taking operation is detected without the elapse of the predetermined time (step S205 No), the note-taking operation detection means 11 repeats the data acquisition.

[0034] The study time calculation means 14 calculates the time obtained by subtracting a predetermined time determined in advance from the time from the study start determination by the study start determination means 12 to the study end determination by the study end determination means 13 as the study time (step S207). The LED of the study time measurement device 10 may be lit according to the calculated length of the study time.

[0035] FIG. 5 is an explanatory diagram of specific study time calculation, where the predetermined time is set to 10 minutes.

[0036] In the case of Fig. 5(1), it is calculated as follows. · Detect the writing operation at time A and determine the start of study. · Continuously detect the writing operation until time B. · Determine the end of study when 10 minutes have passed without detecting the writing operation until time C. · Time from time A to time C (34 minutes) - Predetermined time (10 minutes) = Study time (24 minutes)

[0037] In the case of Fig. 5(2), it is calculated as follows. · Detect the writing operation at time D and determine the start of study. · Continuously detect the writing operation until time E. · 6 minutes have passed without detecting the writing operation until time F (no end determination). · Continuously detect the writing operation until time G. · Determine the end of study when 10 minutes have passed without detecting the writing operation until time H. · Time from time D to time H (56 minutes) - Predetermined time (10 minutes) = Study time (46 minutes)

[0038] The calculated study time data is sent to the terminal 20 and used to enhance the user's learning motivation. For example, it can be set up such that a monster grows according to the length of the study time, or the study time data can be shared with guardians or teachers and set up to give praise.

[0039] The study time measurement device 10 according to this embodiment includes a writing operation detection means 11, a study start determination means 12, a study end determination means 13, and a study time calculation means 14. When the writing operation detection means 11 detects a writing operation, the study start determination means 12 determines that the study has started. When the time during which the writing operation detection means 11 does not detect a writing operation reaches a predetermined time or more, the study end determination means 13 determines that the study has ended. The study time calculation means 14 calculates, as the study time, the time obtained by subtracting a predetermined time from the time from the study start determination to the study end determination. That is, when the time during which no writing operation is detected continues, if it is less than the predetermined time, it is included in the study time, and if it is more than the predetermined time, it is excluded from the study time. Therefore, not only the writing operation but also the time other than the writing operation can be properly evaluated as the study time.

[0040] Further, if it has a reference state registration means 15 for registering the reference state before the writing operation, and the writing operation detection means 11 detects the writing operation due to a change from the reference state, the writing operation can be accurately detected even if the reference state varies depending on the user.

[0041] Also, if the study time calculated by the study time calculation means 14 is set to 0 when it is less than a predetermined minimum time, it is possible to exclude a time that is too short to be evaluated as the study time.

[0042] As described above, according to the study time measurement device according to this embodiment, not only the writing operation but also the time other than the writing operation can be properly evaluated as the study time.

[0043] As described above, the study time measurement device and the study time measurement method according to the embodiment of the present invention have been described. However, the present invention is not limited to the above-described embodiment, and various other modifications are possible.

[0044] For example, something other than a three-axis acceleration sensor may be used as the writing operation detection means, or the writing operation may be detected from other than a change from the reference state.

[0045] In addition to the band-type device, the study time measurement device can also be a ring-type device or a device attached to a writing instrument.

[0046] Also, a part of the functions other than the writing operation detection means of the study time measurement device in the present embodiment may be provided and processed on the terminal side connected by communication, for example, instead of on the device side worn by the user, and the device and the terminal may be configured together as a study time measurement device.
