- a first aspect of the invention relates to a method 100 of interaction with a subtitle displayed in a display area ZA of a digital television screen.
- the subtitle word must be understood as all the text superimposed on an image extracted from a video at a given moment: it may therefore consist of one or more words.
- the method 100 comprises several steps, the sequence of which is shown in FIG. These steps are implemented by a computer Dec coupled to a camera Cam and possibly to a microphone.
- the word computer Dec refers to a device having a memory, image processing functions for tracking one or more fingers of one or more users in the films from the camera and signal processing functions for detecting key words in a sound recording.
- the computer is integrated within a digital television decoder capable of decoding encrypted television signals.
- the first step is the calibration step 101 shown in FIG. 2. This step makes it possible to match the display zone ZA with an interaction zone of the user Zu.
- the interaction zone of the user Zu comprises all the positions in which a user's finger may be when he points to any point of the display zone ZA.
- This calibration step 101 can be performed by several users at the same time or one after the other.
- each user has his own Zu interaction zone, taking into account his positioning with respect to the digital television screen.
- the computer Dec displays a first point C1 on the display area ZA.
- point is meant a point in the mathematical sense of the term or the center of an area that may have, for example, a circular, square or cross shape.
- the camera Cam is then started by the computer or by the user, records a first calibration film and transmits it to the computer.
- a film is understood to mean an image or a plurality of images.
- the computer Dec detects a finger of a user in the first calibration film, records a first position PC1 of this finger and associates it with the position of the first point C1.
- the camera Cam then records a second calibration film and transmits it to the computer, which detects a user's finger in the second calibration film, records a second position PC2 of that finger and associates it with the position of the second point C2.
- the first and second calibration films may be two separate films, the camera interrupting after the calibration of the first point C1 and taking again for the calibration of the second point C2, or two subparts of a single film, the camera filming continuously during the entire calibration step.
- the calibration step 101 can be performed with a greater number of points, for example three points.
- the display zone ZA is preferably a quadrilateral and more preferably a rectangle. It has a first dimension X and a second dimension Y which define a 2D XY mark.
- the three points may for example be the upper left corner, the lower right corner and the center of the display area ZA, the reading of the position of the center of the display area ZA facilitating the management of the perspective.
- Two points are enough if their two coordinates in the XY coordinate system are different. However, calibration is best when using at least three points. Indeed, the first two points are used to calculate the height H user according to the dimension X and the length L user according to the dimension Y of the interaction zone of the user Zu. This zone is shown in dotted lines, in the foreground in FIGS. 3A and 3B. However, if the user is not facing the television, the Zu user interaction area plane may not be parallel to the ZA display area plane: the position of a third point then makes it possible to evaluate an angle between the plane of the interaction zone of the user Zu and the plane of the display zone ZA. In general, the greater the number of points to be pointed, the more robust the calibration.
- a follow-up is set up to detect a presence of a finger of the user and to raise its position.
- This tracking can be performed using, for example a Kalman filter or a recursive Gauss-Newton filter.
- the computer raises the position of a point when the position of the user's finger pointed at the point whose position is to be read has not varied by more than a certain threshold D in absolute value during an interval of time T.
- the finger points to the definitive position (X 0 , Y 0 ) if the following condition is satisfied: vt t - 1 0 ⁇ T: d ((X (t), Y (t )), (X ", Y")) ⁇ D
- t 0 is the moment when the position followed by the finger is the one chosen as the one pointing to the point whose position is to be read
- the position (X 0 , Y 0 ) is then recorded and the position of the next point is read.
- the threshold D may, for example be 5 cm.
- the time interval T may for example be in the range [1 s; 2 s].
- each point of the display area ZA is in correspondence with a point of the interaction zone of the user Zu.
- the interactive display step begins.
- the finger tracking preferably starts at the same time as the video but could also start before. Indeed, the tracking is carried out continuously during the video using, for example, a Kalman filter or a recursive Gauss-Newton filter on the film taken by the camera Cam.
- the camera Cam has already been started by the computer or by the user at the beginning of the calibration step and has been filming since then, but it may also have been switched off at the end of the calibration step and be turned on again. at the beginning of the interactive display step. In all cases, the camera starts taking a movie at the beginning of the interactive display step.
- the film during the interactive display step may be separate from the calibration film or films, the camera stopping after the calibration step and resuming in the interactive display step, or the film of the interactive display step and the calibration film or films can be several sub-parts of a single film, the camera filming continuously.
- the video continues normally as long as there is no pause 103.
- the interactive display step can be performed by several users by setting up a tracking for each user.
- the computer Dec to pause, the computer Dec must detect the presence of a finger of the user in the display area ZA.
- the computer pauses the video when the position of the finger of the user has not varied by more than a certain threshold D2 in absolute value during a time interval T2.
- the threshold D2 may be the same or different from the threshold D.
- the threshold D2 may, for example be 10 cm.
- This time interval T2 may be the same or different from the time interval T.
- the time interval T2 may for example be in the range [0.5 s; 1.5 s].
- a microphone captures the sound environment in the form of a signal and transmits it to the computer Dec. If a key word is spoken, the detector pauses the video 103. This key word can be, for example, example "pause”.
- the detection of keywords can for example be performed by a dynamic programming algorithm based on the normalization of time or a WUW algorithm (for "Wake-Up-Word").
- a finger of the user marks a single stop in the display area ZA.
- the position pointed at the screen is estimated using the position of the finger filmed by the camera Cam and data obtained during the calibration step 101.
- the height H user and the length L user of the interaction zone of the user Zu make it possible to calculate a coefficient of horizontal sensitivity a and a coefficient of vertical sensitivity b with the following formulas:
- L TV is the length of the display area ZA and H TV is the height of the display area ZA.
- the display area ZA is always the same, for example the bottom quarter of the television.
- the position of each point of the display area ZA pointed during the calibration step 101 is associated with the position of the pointing finger.
- the position of the point C1 (x 1 , y 1 ) of the display area ZA pointed during the calibration step 101 is associated with the position PC1 (X 1 , Y 1 ) of the finger pointing towards this point. If we estimate the position of the finger filmed by the camera Cam at (Xi + dx, YL + dy), the position pointed on the screen will be (X- L + a * dx ⁇ + b * dy).
- Each word corresponding virtually to a rectangle on the screen the rectangle corresponding to the position (X- L + a * dx, + b * dy) is selected. This case is illustrated in Figure 3A.
- the user moves his finger in the interaction zone Zu shown in dashed lines, height H user and length L user .
- a correspondence is established between the position of the user's finger and a position on the screen close to the word "hello" which is thus selected.
- the computer raises the position (Xi + dx, + dy) when the position of the user's finger has not varied by more than a certain threshold in absolute value during a certain time interval.
- This threshold may be the same or different from the threshold D and / or the threshold D2.
- This time interval may be the same or different from the time interval T and / or the time interval T2.
- the user can select several words if, for example, the calculator is set to select one or more adjacent words of the pointed word or if the gesture command is used in combination with a command voice, for example, the user says "two" to select the word pointed and the two following.
- the user's finger makes a movement after the first extended station and marks a second stop once the movement is completed. If the position of the first extended station is different from that of the second extended station, the calculator preferentially interprets the fact that the finger points to the place of the beginning of the selection and the place of the end of the selection. This case is illustrated in FIGS. 3A and 3B. The user moves his finger in the interaction zone Zu.
- the finger marks a first stop at the PS1 position which points a first word "hello".
- the first word "hello” is then selected which is materialized by a frame of the word.
- the finger then performs a linear movement before marking a second stop at the PS2 position which points a second word "sir" in Figure 3B.
- the second word is then added to the selection which is materialized by an extension of the previous frame to encompass the two words.
- the first and second words may follow or be separated by one or more other words.
- the calculator is able to draw a frame or outline area by selecting all the words between the first and second words even if the first and second words are not on the same subtitle line.
- the computer preferentially interprets the case where the user's finger has surrounded the selection.
- key words pronounced by a user and recorded by a microphone may allow for example to start, start again or finish the drawing of the contour area of the word or words to be selected.
- a key word can be for example "to start again”.
- the selection step is performed at least partially by a gestural control, which provides a better comfort for the user by avoiding a tedious and / or difficult step, for example say a word which he is not sure. pronunciation with the risk that his command is not understood by the calculator, or count the position of the first word he wants to select and then count the position of the last word he wants to select or count the number of words in the selection.
- the duration of the selection step is significantly reduced and contributes to the user keeps the wire of his viewing.
- the gesture controls are more robust than the voice commands: to detect a key word, it is necessary that the background is low enough and preferably that no one other than the user speaks at the risk of triggering involuntary commands .
- the voice command is poorly adapted to a multi-user mode.
- the introduction of a gesture control makes it possible to give a starting point to the selection, making it more precise and faster even combined with a voice command, which makes it possible not to degrade the viewing.
- a visual aid can be added superimposed on the screen to indicate to the user what is the current position estimated for the pointing of his finger.
- This visual aid may for example be a color point, for example red or green. Each user may have a different color pointer.
- This visual aid can be set up from the start of the video 102 or only while the video is paused 103.
- the validation is performed by gesture control.
- the user points a validation area being a part of the display area ZA where is indicated for example the word "validation”.
- the validation is performed by a voice command.
- the user pronounces the keyword "validation”.
- a list of action options is displayed on the screen, each option having an action zone being a part of the zone.
- ZA display A finger of the user marks a stop on the action zone corresponding to the action he wishes to perform with the previously validated selection.
- each action is associated with a particular gesture, for example raising the thumb corresponds to a translation of the selection. It is therefore necessary to perform the gesture associated with the action to choose to perform this action.
- a key word of action is pronounced. For example, the user pronounces the keyword "translation”.
- an action has been previously preconfigured and this action will therefore be performed automatically for each selection.
- a message confirming the execution of the action may appear on the screen.
- a selection is returned to the selection screen or a video resumption.
- a finger of the user marks a stop on a return zone being a part of the display zone ZA where is indicated for example the word "return";
- the return is made by a voice command.
- the user pronounces the keyword "return”.
