The speaker 9 has a function of broadcasting sound information such as a buzzer sound and a sound announcement. For example, the speaker 9 broadcasts an audio announcement indicating the operation status of the elevator based on a signal from the control panel 3.
　行先階釦５は、例えば、かごが停止可能な各階に対応して複数設けられている。行先階釦５は、対応する階へ移動するための通常の呼び登録操作を受け付ける。通常の呼び登録操作は、例えば、手で行先階釦５に触れること又は行先階釦５を押し込むこと等である。 For example, a plurality of destination floor buttons 5 are provided corresponding to each floor where the car can be stopped.

　図１に示すように、操作盤１には、例えば、視線認識カメラ１０及び入力開始マーク１１が設けられている。視線認識カメラ１０は、例えば、複数設けられている。図１は、視線認識カメラ１０として第１カメラ１２及び第２カメラ１３の２つが設けられた場合を例示している。 As shown in FIG. 1, the operation panel 1 is provided with, for example, a line-of-sight recognition camera 10 and an input start mark 11. For example, a plurality of line-of-sight recognition cameras 10 are provided. FIG. 1 exemplifies a case where the first camera 12 and the second camera 13 are provided as the line-of-sight recognition camera 10.
　入力開始マーク１１は、例えば、操作盤１の上下方向における中央よりも上側に配置されている。入力開始マーク１１は、例えば、操作盤１において報知部４よりも下側に配置されている。入力開始マーク１１は、例えば、操作盤１において行先階釦５よりも上側に配置されている。 The input start mark 11 is, for example, arranged above the center of the operation panel 1 in the vertical direction. For example, the input start mark 11 is arranged below the notification unit 4 on the operation panel 1. For example, the input start mark 11 is arranged on the operation panel 1 above the destination floor button 5.
　第１カメラ１２は、例えば、操作盤１の上下方向における中央よりも上側に配置されている。第１カメラ１２は、例えば、操作盤１において報知部４よりも下側に配置されている。第１カメラ１２は、例えば、操作盤１において入力開始マーク１１よりも下側に配置されている。第１カメラ１２は、例えば、操作盤１において行先階釦５よりも上側に配置されている。 The first camera 12 is disposed, for example, above the center of the operation panel 1 in the vertical direction. For example, the first camera 12 is disposed below the notification unit 4 in the operation panel 1. For example, the first camera 12 is disposed below the input start mark 11 on the operation panel 1. For example, the first camera 12 is arranged on the operation panel 1 above the destination floor button 5.
　第２カメラ１３は、例えば、操作盤１の上下方向における中央よりも下側に配置されている。第２カメラ１３は、例えば、操作盤１において行先階釦５よりも下側に配置されている。第２カメラ１３は、例えば、操作盤１において戸開釦６及び戸閉釦７よりも上側に配置されている。 The second camera 13 is disposed, for example, below the center of the operation panel 1 in the vertical direction. For example, the second camera 13 is disposed below the destination floor button 5 on the operation panel 1. For example, the second camera 13 is disposed above the door opening button 6 and the door closing button 7 in the operation panel 1.
　このように、視線認識カメラ１０は、例えば、高さが異なる複数の位置に設けられている。第１カメラ１２の位置する高さは、例えば、立っている状態の大人１４の目の高さに近い。第２カメラ１３の位置する高さは、例えば、立っている状態の子供１５の目の高さに近い。また、第２カメラ１３の位置する高さは、例えば、車椅子利用者の目の高さに近い。視線認識カメラ１０で撮影された映像は、視線認識装置２に送られる。 Thus, the line-of-sight recognition camera 10 is provided at a plurality of positions having different heights, for example. The height at which the first camera 12 is positioned is, for example, close to the height of the eyes of the adult 14 standing. The height at which the second camera 13 is positioned is, for example, close to the height of the eyes of the standing child 15. Moreover, the height at which the second camera 13 is located is close to the eye level of the wheelchair user, for example. The video imaged by the line-of-sight recognition camera 10 is sent to the line-of-sight recognition device 2.
　図２は、実施の形態１におけるエレベーターの呼び登録システムの機能ブロック図である。 FIG. 2 is a functional block diagram of the elevator call registration system in the first embodiment.
　図２に示すように、行先階釦５には、釦灯１６が内蔵されている。例えば、利用者により行先階釦５に対して通常の呼び登録操作が行われた場合、当該行先階釦５の釦灯１６が点灯する。釦灯１６は、戸開釦６及び戸閉釦７にも内蔵されていてもよい。 As shown in FIG. 2, the destination floor button 5 has a button light 16 incorporated therein. For example, when a normal call registration operation is performed on the destination floor button 5 by the user, the button lamp 16 of the destination floor button 5 is turned on. The button lamp 16 may be incorporated in the door opening button 6 and the door closing button 7.
　図２に示すように、視線認識装置２は、例えば、視線認識部１７、開始判定部１８、補正部１９、距離演算部２０、操作検出部２１、釦灯制御部２２、通信部２３及び発報部２４を有する。制御盤３は、呼び登録部２５及び運転制御部２６を有する。 As shown in FIG. 2, the line-of-sight recognition device 2 includes, for example, a line-of-sight recognition unit 17, a start determination unit 18, a correction unit 19, a distance calculation unit 20, an operation detection unit 21, a button lamp control unit 22, a communication unit 23, and a calling unit. An information section 24 is provided. The control panel 3 includes a call registration unit 25 and an operation control unit 26.
　視線認識部１７は、視線認識カメラ１０で撮影された映像に基づいて、利用者の視線が向けられている位置を検出する。視線認識部１７は、例えば、利用者の視線の向きだけでなく、まばたきを検出してもよい。 The line-of-sight recognition unit 17 detects the position where the line of sight of the user is directed based on the video taken by the line-of-sight recognition camera 10. For example, the line-of-sight recognition unit 17 may detect not only the direction of the user's line of sight but also blinking.
　視線認識部１７は、例えば、操作盤１の表面と平行な予め設定された平面領域における位置を検出する。当該平面領域は、例えば、操作盤１の物理的な表面でもよい。当該平面領域は、例えば、かご内の物理的な壁面でもよい。当該平面領域は、例えば、仮想的な平面でもよい。 The line-of-sight recognition unit 17 detects, for example, a position in a preset plane region parallel to the surface of the operation panel 1. For example, the planar area may be a physical surface of the operation panel 1. The plane area may be, for example, a physical wall surface in the car. The plane area may be a virtual plane, for example.
　当該平面領域は、例えば、仮想的な複数のマス目に分割されている。視線認識部１７は、例えば、利用者の視線が向けられている位置として、当該平面領域におけるいずれかのマス目を検出する。仮想的なマス目の大きさは、例えば、行先階釦５の大きさ以下に設定されている。仮想的なマス目の大きさは、例えば、行先階釦５の大きさの５分の１以上に設定されている。 The plane area is divided into a plurality of virtual squares, for example. The line-of-sight recognition unit 17 detects, for example, any square in the plane area as a position where the user's line of sight is directed. The size of the virtual grid is set to be equal to or smaller than the size of the destination floor button 5, for example. The size of the virtual cell is set to, for example, one fifth or more of the size of the destination floor button 5.
　開始判定部１８は、利用者によって操作盤１に対する視線入力が開始されたか否かを判定する。開始判定部１８は、例えば、入力開始マーク１１に対応する位置に一定時間継続して利用者の視線が向けられたことが視線認識部１７により検出された場合に、視線入力が開始されたと判定する。また、開始判定部１８は、例えば、入力開始マーク１１に対応する位置に一定時間継続して利用者の視線が向けられたことに加えて、複数回のまばたきが視線認識部１７により検出された場合に、視線入力が開始されたと判定してもよい。 The start determination unit 18 determines whether or not the line of sight input to the operation panel 1 has been started by the user. The start determination unit 18 determines that the line-of-sight input has been started, for example, when the line-of-sight recognition unit 17 detects that the user's line of sight has been directed to a position corresponding to the input start mark 11 for a certain period of time. To do. In addition, the start determination unit 18 detects, for example, that the user's line of sight has been directed to a position corresponding to the input start mark 11 for a certain period of time, and a plurality of blinks have been detected by the line-of-sight recognition unit 17. In this case, it may be determined that the line-of-sight input has started.
　このように、入力開始マーク１１は、利用者が視線入力を開始するために見つめる目印として設けられている。なお、当該目印として、例えば、入力開始マーク１１の代わりにインジケーター８又はいずれかの行先階釦５等を用いてもよい。 As described above, the input start mark 11 is provided as a mark that the user looks at in order to start the line-of-sight input. As the mark, for example, the indicator 8 or any destination floor button 5 may be used instead of the input start mark 11.
　補正部１９は、例えば、入力開始マーク１１に対して利用者の視線が向けられている時の視線認識部１７による検出位置と入力開始マーク１１の中央位置とのズレに基づいて、視線認識部１７による検出位置を補正する。補正部１９は、例えば、入力開始マーク１１に対して利用者の視線が向けられている間に補正を行う。 For example, the correction unit 19 is based on the deviation between the detection position by the line-of-sight recognition unit 17 and the center position of the input start mark 11 when the user's line of sight is directed toward the input start mark 11. The detection position by 17 is corrected. For example, the correction unit 19 performs correction while the user's line of sight is directed toward the input start mark 11.
　図３は、実施の形態１における入力開始マークの拡大図である。図３は、仮想的な複数のマス目を入力開始マーク１１上に重ねた状態を示している。 FIG. 3 is an enlarged view of the input start mark in the first embodiment. FIG. 3 shows a state where a plurality of virtual squares are superimposed on the input start mark 11.
　図３を参照して、補正部１９による補正の具体例を説明する。図３に示す入力開始マーク１１の中央位置に対応するマス目は、Ｘ軸方向で４番目且つＹ軸方向で３番目のマス目である。例えば、Ｘ軸方向で３番目且つＹ軸方向で５番目のマス目が視線認識部１７により検出された場合、補正部１９は、検出位置のＸ軸成分を１マス増加させ、検出位置のＹ軸成分を２マス減少させる。このように、補正部１９は、例えば、視線認識部１７により検出されたマス目と入力開始マーク１１の中央位置に対応するマス目とのズレに基づいて、視線認識部１７による検出位置をマス目単位で補正する。 A specific example of correction by the correction unit 19 will be described with reference to FIG. The square corresponding to the center position of the input start mark 11 shown in FIG. 3 is the fourth square in the X-axis direction and the third square in the Y-axis direction. For example, when the gaze recognition unit 17 detects the third cell in the X-axis direction and the fifth cell in the Y-axis direction, the correction unit 19 increases the X-axis component of the detection position by one cell, and Decrease the axis component by 2 squares. In this way, the correction unit 19 determines, for example, the detection position by the line-of-sight recognition unit 17 based on the shift between the grid detected by the line-of-sight recognition unit 17 and the grid corresponding to the center position of the input start mark 11. Correct by eye.
　距離演算部２０は、視線認識カメラ１０と利用者の目との距離を演算する。距離演算部２０は、例えば、２台の視線認識カメラ１０による距離演算を行うことで、第１カメラ１２及び第２カメラ１３のそれぞれについて、利用者の目との距離を演算する。 The distance calculation unit 20 calculates the distance between the line-of-sight recognition camera 10 and the user's eyes. The distance calculation unit 20 calculates the distance from the user's eyes for each of the first camera 12 and the second camera 13 by performing a distance calculation using, for example, the two line-of-sight recognition cameras 10.
　視線認識部１７は、例えば、距離演算部２０による演算の完了後には、第１カメラ１２及び第２カメラ１３のうち演算された距離がより小さい一方で撮影された映像のみに基づいて検出を行う。つまり、視線認識部１７は、例えば、複数の視線認識カメラ１０のうち利用者の目に最も近い１つの視線認識カメラ１０で撮影された映像に基づいて当該利用者の視線が向けられている位置を検出し、他の視線認識カメラ１０で撮影された映像に基づく検出を行わない。このようにして、使用される視線認識カメラ１０が選択される。 For example, after the calculation by the distance calculation unit 20 is completed, the line-of-sight recognition unit 17 performs detection based only on the captured image while the calculated distance is smaller among the first camera 12 and the second camera 13. . That is, the line-of-sight recognition unit 17 is, for example, a position where the line of sight of the user is directed based on an image captured by one line-of-sight recognition camera 10 closest to the user's eye among the plurality of line-of-sight recognition cameras 10. Is detected, and detection based on the video imaged by another line-of-sight recognition camera 10 is not performed. In this way, the line-of-sight recognition camera 10 to be used is selected.
　操作検出部２１は、視線認識部１７による検出位置に基づいて呼び登録操作を検出する。操作検出部２１は、例えば、補正部１９により補正された検出位置に基づいて呼び登録操作を検出する。操作検出部２１は、例えば、視線認識部１７により行先階釦５の位置が一定時間継続して検出されたことを当該行先階釦５に対応する階へ移動するための呼び登録操作として検出する。また、操作検出部２１は、例えば、視線認識部１７により行先階釦５の位置が一定時間継続して検出され且つ複数回のまばたきが検出されたことを当該行先階釦５に対応する階へ移動するための呼び登録操作として検出してもよい。つまり、操作検出部２１は、視線入力による呼び登録操作を検出する。 The operation detection unit 21 detects a call registration operation based on the detection position by the line-of-sight recognition unit 17. For example, the operation detection unit 21 detects a call registration operation based on the detection position corrected by the correction unit 19. For example, the operation detection unit 21 detects that the position of the destination floor button 5 is continuously detected by the line-of-sight recognition unit 17 for a certain period of time as a call registration operation for moving to the floor corresponding to the destination floor button 5. . For example, the operation detection unit 21 detects that the position of the destination floor button 5 has been continuously detected for a certain period of time by the line-of-sight recognition unit 17 and that a plurality of blinks has been detected, to the floor corresponding to the destination floor button 5. You may detect as call registration operation for moving. That is, the operation detection unit 21 detects a call registration operation based on a line-of-sight input.
　操作検出部２１は、開始判定部１８により視線入力が開始されたと判定される前には、視線入力による呼び登録操作の検出を行わない。操作検出部２１は、開始判定部１８により視線入力が開始されたと判定された後に、視線入力による呼び登録操作の検出を行う。操作検出部２１は、例えば、視線入力が開始されたと判定されてから予め設定された制限時間が経過するまでに視線認識部１７により行先階釦５の位置が検出されない場合、視線入力による呼び登録操作の検出を中止する。 The operation detection unit 21 does not detect the call registration operation based on the line-of-sight input before the start determination unit 18 determines that the line-of-sight input has started. The operation detection unit 21 detects a call registration operation based on the line-of-sight input after the start determination unit 18 determines that the line-of-sight input has started. For example, when the position of the destination floor button 5 is not detected by the line-of-sight recognition unit 17 until the preset time limit elapses after it is determined that the line-of-sight input is started, the operation detection unit 21 registers the call by line-of-sight input. Stop detecting operations.
　釦灯制御部２２は、釦灯１６を点灯及び消灯させる。釦灯制御部２２は、例えば、操作検出部２１により行先階釦５に対応する階へ移動するための呼び登録操作が検出された場合に、当該行先階釦５の釦灯１６を点灯させる。 The button lamp control unit 22 turns on and off the button lamp 16. For example, when the operation detection unit 21 detects a call registration operation for moving to the floor corresponding to the destination floor button 5, the button lamp control unit 22 lights the button lamp 16 of the destination floor button 5.
　通信部２３は、制御盤３との通信を行う。通信部２３は、例えば、操作検出部２１により行先階釦５に対応する階へ移動するための呼び登録操作が検出された場合に、呼び登録情報を制御盤３に送信する。この呼び登録情報は、例えば、当該行先階釦５に対応する階を示す情報である。 The communication unit 23 communicates with the control panel 3. For example, when the operation detection unit 21 detects a call registration operation for moving to the floor corresponding to the destination floor button 5, the communication unit 23 transmits call registration information to the control panel 3. This call registration information is information indicating a floor corresponding to the destination floor button 5, for example.
　呼び登録部２５は、例えば、行先階釦５に対する通常の呼び登録操作に基づいて、呼びを登録する。呼び登録部２５は、例えば、通信部２３から送信された呼び登録情報に基づいて、呼びを登録する。つまり、呼び登録部２５は、例えば、操作検出部２１により検出された呼び登録操作に基づいて呼びを登録する。 The call registration unit 25 registers a call based on a normal call registration operation for the destination floor button 5, for example. For example, the call registration unit 25 registers a call based on the call registration information transmitted from the communication unit 23. That is, the call registration unit 25 registers a call based on the call registration operation detected by the operation detection unit 21, for example.
　運転制御部２６は、巻上機の駆動を制御することで、エレベーターの運転を制御する。運転制御部２６は、例えば、呼び登録部２５により登録された呼びに対してかごを応答させる。 The operation control unit 26 controls the operation of the elevator by controlling the driving of the hoisting machine. For example, the operation control unit 26 causes the car to respond to the call registered by the call registration unit 25.
　発報部２４は、視線入力に関する情報を報知部４から報知させる。発報部２４は、少なくとも、視線入力に関する音声情報をスピーカー９から放送させる。 The reporting unit 24 causes the reporting unit 4 to report information on the line-of-sight input. The alerting | reporting part 24 broadcasts the audio | voice information regarding a gaze input from the speaker 9 at least.
　発報部２４は、例えば、視線認識部１７による検出位置が入力開始マーク１１上にあり、且つ、当該検出位置が一定しない場合に、入力開始マーク１１の中央を見つめるよう利用者に促すメッセージを報知部４から報知させる。 For example, when the detection position by the line-of-sight recognition unit 17 is on the input start mark 11 and the detection position is not constant, the notification unit 24 sends a message prompting the user to look at the center of the input start mark 11. The notification unit 4 notifies the user.
　発報部２４は、例えば、開始判定部１８により視線入力が開始されたと判定された場合に、視線入力による呼び登録操作を利用者に促すメッセージを報知部４から報知させる。このメッセージは、例えば、「視線入力の受け付けを開始します。呼び登録する階の釦を見つめてください」のように、端的に表現したものとする。 For example, when the start determination unit 18 determines that the line-of-sight input is started, the notification unit 24 causes the notification unit 4 to notify a message that prompts the user to perform a call registration operation based on the line-of-sight input. This message is simply expressed, for example, “Start accepting line-of-sight input. Look at the button on the floor to register for call”.
　発報部２４は、例えば、通信部２３から制御盤３へ呼び登録情報が送信された後に、視線入力による呼び登録が完了した旨のメッセージを報知部４から報知させる。このメッセージは、例えば、「ＸＸ階に呼び登録完了しました」のように、端的に表現したものとする。 For example, after the call registration information is transmitted from the communication unit 23 to the control panel 3, the notification unit 24 causes the notification unit 4 to notify a message that call registration by line-of-sight input is completed. This message is simply expressed as, for example, “Call registration completed on the XX floor”.
　図４は、実施の形態１におけるエレベーターの呼び登録システムの動作例を示すフローチャートである。 FIG. 4 is a flowchart showing an operation example of the elevator call registration system according to the first embodiment.
　視線認識装置２は、入力開始マーク１１に一定時間継続して視線が向けられたか否かを判定する（ステップＳ１０１）。入力開始マーク１１に一定時間継続して視線が向けられていない場合、ステップＳ１０１の処理が繰り返される。 The line-of-sight recognition device 2 determines whether or not the line-of-sight has been directed to the input start mark 11 for a certain period of time (step S101). If the line of sight is not directed to the input start mark 11 for a certain period of time, the process of step S101 is repeated.
　ステップＳ１０１で、入力開始マーク１１に一定時間継続して視線が向けられたと判定された場合、視線認識装置２は、視線入力による呼び登録操作に使用する視線認識カメラ１０を１つ選択する（ステップＳ１０２）。視線認識装置２は、視線入力による呼び登録操作の受け付けを開始する（ステップＳ１０３）。視線認識装置２は、視線入力による呼び登録操作を利用者に促すメッセージを報知部４から報知させる（ステップＳ１０４）。 If it is determined in step S101 that the line of sight has been continuously directed to the input start mark 11, the line-of-sight recognition device 2 selects one line-of-sight recognition camera 10 to be used for a call registration operation by line-of-sight input (step) S102). The line-of-sight recognition device 2 starts accepting a call registration operation based on line-of-sight input (step S103). The line-of-sight recognition device 2 causes the notification unit 4 to notify a message that prompts the user to perform a call registration operation based on line-of-sight input (step S104).
　視線認識装置２は、制限時間が経過したか否かを判定する（ステップＳ１０５）。ステップＳ１０５で、制限時間が経過したと判定された場合、視線認識装置２は、ステップＳ１０１の処理を行う。 The line-of-sight recognition device 2 determines whether or not the time limit has elapsed (step S105). If it is determined in step S105 that the time limit has elapsed, the line-of-sight recognition device 2 performs the process of step S101.
　ステップＳ１０５で、制限時間が経過していないと判定された場合、視線認識装置２は、行先階釦５に一定時間継続して視線が向けられたか否かを判定する（ステップＳ１０６）。ステップＳ１０６で、行先階釦５に一定時間継続して視線が向けられていないと判定された場合、視線認識装置２は、ステップＳ１０５の処理を行う。 When it is determined in step S105 that the time limit has not elapsed, the line-of-sight recognition device 2 determines whether or not the line of sight is continuously directed to the destination floor button 5 for a certain period of time (step S106). If it is determined in step S106 that the line of sight is not continuously directed to the destination floor button 5 for a certain period of time, the line-of-sight recognition device 2 performs the process of step S105.
　ステップＳ１０６で、行先階釦５に一定時間継続して視線が向けられたと判定された場合、視線認識装置２は、該当する行先階釦５の釦灯１６を点灯させる（ステップＳ１０７）。視線認識装置２は、エレベーターの制御盤３に呼び登録情報を送信する（ステップＳ１０８）。視線認識装置２は、視線入力による呼び登録が完了した旨のメッセージを報知部４から報知させる（ステップＳ１０９）。 When it is determined in step S106 that the line of sight is continuously directed to the destination floor button 5 for a certain period of time, the line-of-sight recognition device 2 turns on the button lamp 16 of the corresponding destination floor button 5 (step S107). The line-of-sight recognition device 2 transmits the call registration information to the control panel 3 of the elevator (step S108). The line-of-sight recognition device 2 notifies the notification unit 4 of a message indicating that call registration by line-of-sight input has been completed (step S109).
　視線認識装置２は、例えば、エレベーターの乗場に設けられた操作盤１に適用することもできる。この場合、視線入力によるエレベーターの呼び登録を乗場で行うことができる。この場合、操作検出部２１は、例えば、視線認識部１７により上方向釦又は下方向釦の位置が検出されたことを呼び登録操作として検出してもよい。 The line-of-sight recognition device 2 can be applied to, for example, the operation panel 1 provided at the elevator hall. In this case, the elevator call registration by the line-of-sight input can be performed at the landing. In this case, for example, the operation detection unit 21 may detect that the position of the up button or the down button is detected by the line-of-sight recognition unit 17 as a call registration operation.
　報知部４、視線認識カメラ１０及び入力開始マーク１１は、例えば、かご内又は乗場において操作盤１とは別個に設けられてもよい。この場合、視線認識カメラ１０は、例えば、かご内又は乗場において高さが異なる複数の位置に設けられていればよい。この場合、視線認識カメラ１０及び入力開始マーク１１は、例えば、利用者が入力開始マーク１１又は行先階釦５を見ている状態で当該利用者の視線認識が可能な位置関係にあればよい。 The notification unit 4, the line-of-sight recognition camera 10, and the input start mark 11 may be provided separately from the operation panel 1 in a car or a landing, for example. In this case, the line-of-sight recognition camera 10 only needs to be provided at a plurality of positions having different heights in the car or the landing, for example. In this case, the line-of-sight recognition camera 10 and the input start mark 11 may be in a positional relationship that allows the user to recognize the line of sight while the user is looking at the input start mark 11 or the destination floor button 5, for example.
　実施の形態１において、操作検出部２１は、例えば、開始判定部１８により視線入力が開始されたと判定された場合に、視線認識部１７による検出位置に基づいて呼び登録操作を検出する。開始判定部１８は、例えば、かご内又は乗場の予め設定された目印に対して利用者の視線が向けられたことが視線認識部１７により検出された場合に、視線入力が開始されたと判定する。このため、実施の形態１によれば、精度の高い視線認識を行うことができる。その結果、視線入力によるエレベーターの呼び登録を円滑に行うことができる。また、視線入力を行う意思のない利用者の視線に基づいて誤った呼びが登録されることを防止できる。 In Embodiment 1, the operation detection unit 21 detects a call registration operation based on the detection position by the line-of-sight recognition unit 17 when, for example, the start determination unit 18 determines that the line-of-sight input has started. The start determination unit 18 determines that the line-of-sight input is started when the line-of-sight recognition unit 17 detects that the user's line of sight is directed to a preset mark in the car or the hall, for example. . Therefore, according to the first embodiment, it is possible to perform line-of-sight recognition with high accuracy. As a result, elevator call registration by line-of-sight input can be performed smoothly. Moreover, it is possible to prevent an erroneous call from being registered based on the line of sight of a user who does not intend to perform line-of-sight input.
　実施の形態１において、補正部１９は、例えば、かご内又は乗場の目印に対して利用者の視線が向けられている時の視線認識部１７による検出位置と目印の中央位置とのズレに基づいて、視線認識部１７による検出位置を補正する。このため、実施の形態１によれば、精度の高い視線認識を行うことができる。 In the first embodiment, the correction unit 19 is based on, for example, a deviation between the detection position by the line-of-sight recognition unit 17 and the center position of the mark when the user's line of sight is directed toward the mark in the car or the hall. Thus, the detection position by the line-of-sight recognition unit 17 is corrected. Therefore, according to the first embodiment, it is possible to perform line-of-sight recognition with high accuracy.
　実施の形態１において、視線認識部１７は、例えば、利用者の視線が向けられている位置として、仮想的な複数のマス目に分割された平面領域におけるいずれかのマス目を検出する。補正部１９は、例えば、視線認識部１７による検出位置をマス目単位で補正する。このため、実施の形態１によれば、精度の高い視線認識を行うことができる。なお、不必要にマス目を細かく設定しないことで、処理時間が増加することを抑制できる。 In the first embodiment, the line-of-sight recognition unit 17 detects, for example, any square in a plane region divided into a plurality of virtual squares as the position where the user's line of sight is directed. For example, the correction unit 19 corrects the detection position by the line-of-sight recognition unit 17 in units of squares. Therefore, according to the first embodiment, it is possible to perform line-of-sight recognition with high accuracy. In addition, it can suppress that processing time increases by not setting the grid | lattice finely unnecessarily.
　実施の形態１において、呼び登録部２５は、例えば、行先階釦５に触れることで行われる通常の呼び登録操作及び操作検出部２１により検出される呼び登録操作の双方に基づいて、呼びを登録する。このため、実施の形態１によれば、エレベーターの従来の呼び登録機能はそのままに、視線入力による呼び登録が可能となる。 In the first embodiment, the call registration unit 25 registers a call based on both a normal call registration operation performed by touching the destination floor button 5 and a call registration operation detected by the operation detection unit 21, for example. To do. For this reason, according to the first embodiment, call registration by line-of-sight input can be performed without changing the conventional call registration function of the elevator.
　実施の形態１において、発報部２４は、例えば、かご内又は乗場に設けられた報知部４から視線入力に関する情報を報知させる。発報部２４は、例えば、開始判定部１８により視線入力が開始されたと判定された場合に、視線入力による呼び登録操作を促す情報を報知部４から報知させる。このため、実施の形態１によれば、視線入力による操作手順を利用者に理解させることができる。 In the first embodiment, the reporting unit 24 informs the user of information related to the line-of-sight input from, for example, the reporting unit 4 provided in the car or at the landing. For example, when the start determination unit 18 determines that the line-of-sight input has been started, the notification unit 24 causes the notification unit 4 to notify information that prompts a call registration operation based on the line-of-sight input. For this reason, according to Embodiment 1, it is possible to make the user understand the operation procedure by the line-of-sight input.
　実施の形態１において、視線認識カメラ１０は、例えば、操作盤１において高さが異なる複数の位置に設けられている。視線認識部１７は、複数の視線認識カメラ１０のうち利用者の目に最も近い１つの視線認識カメラ１０で撮影された映像に基づいて当該利用者の視線が向けられている位置を検出する。このため、実施の形態１によれば、個々の利用者の目の高さに応じて、精度の高い視線認識を行うことができる。また、１つの視線認識カメラ１０のみを用いることで、視線認識の処理速度が低下することを抑制できる。 In Embodiment 1, the line-of-sight recognition camera 10 is provided at a plurality of positions with different heights on the operation panel 1, for example. The line-of-sight recognition unit 17 detects a position where the line of sight of the user is directed based on an image captured by one line-of-sight recognition camera 10 closest to the user's eye among the plurality of line-of-sight recognition cameras 10. For this reason, according to Embodiment 1, high-precision line-of-sight recognition can be performed according to the eye height of each user. Moreover, it can suppress that the processing speed of gaze recognition falls by using only one gaze recognition camera 10. FIG.
