Abstract

A system for purveying to a user information including images, for example a course of learning, and verifying the identity and physical presence of the user during use of the information includes in combination a device for viewing images on a screen (15), unequivocal user identification means (14, 17), means (16, 17) of calculating the attention of the user to the images on the screen that supply a calculated attention figure, and control means (11) that receive user identification data from the identification means and verify that during purveyance of the information the calculated attention­figure of the identified user does not fall below a preset minimum figure. If necessary, the course can be suspended and resumed several times and a reliable certification that the user has really followed the course can be realized even without there having been surveillance by someone. A method is also described.

Description

"SYSTEM, METHOD AND APPARATUS FOR CONTROL OF PURVEYANCE TO A USER OF INFORMATION WITH IMAGES"

The present invention relates to a device and methods for control of purveyance of information including images and verification of the presence and identity of a user to whom images are purveyed with the possibility of being able to determine whether a particular user has given sufficient attention to the images . In particular, this can .be advantageously applied to purveyance of automated courses (delivered for example through a personal computer equipped with a course on optical support or sent him over a computer network) and with the need to be able to determine at the end of the course if a particular user has followed it correctly.

Nowadays, the chances offered by computers to be able to package courses, even iterative, with no need of a human teacher during use of the course are ever more numerous . This allows those wanting to follow one of these courses to reduce costs and make better use of their time. For example, it might be convenient to follow a course of interest directly at home at any time considered convenient without thereby having to undergo place and/or time limits . The problem of allowing the user freedom to follow one of such courses without human surveillance is that there is no guarantee of the real attendance of the user at the course. This prevents using the system with courses that lead to some form of final certification of attendance at the course. For example, this can happen for professional updating courses or for courses like those in use in some countries for recovery of driver's license points lost due to committing traffic offences.

The general purpose of the present invention is to supply a method and an information purveyance system including images and allowing determination of the identity of the user and calculating his degree of attention during purveyance of the information. In particular, the information delivered is part of a learning course. In view of this purpose it was sought to provide in accordance with the present invention a system of verifying the presence, attention and identification parameters of a user during purveyance to the user of information including in combination a device for viewing the images on a screen, means of unequivocal identification of the user, means of calculating the attention of the user to the images on the screen which would supply a calculated attention figure, means of control that receive the user's identification data from the identification means and verify that during purveyance of the information the calculated attention figure of the identified user does not fall below a preset minimum figure.

Again in accordance with the present invention it was also sought to realize a method of purveyance to a user of information including images and associated -with a course while at the same time checking the effective attendance of the user at the course and including the steps of identifying a user through a biometric data detection procedure, starting the viewing of images making up part of the course and associated with the identified user, automatically calculating the user's degree of attention, and using the user's degree of attention to check the progress of the course. To clarify the explanation of the innovative principles of the present invention and its advantages compared with the prior art there is described below with the aid of the annexed drawings a possible embodiment thereof by way of non-limiting example applying said principles. In the drawings :

FIG 1 shows a diagrammatic view of a system in accordance with the present invention; and

FIG 2 shows a block diagram of the management of equipment in accordance with the present inventio . With reference to the figures, multimedia equipment for use of the course is described by way of example. Said application, even if preferred, is not the only one for the present invention. FIG 1 shows equipment designated as a whole by reference number 10 making up part of the system in accordance with the present invention. Said equipment 10 includes a screen 15 on which are shown images to which the user must pay attention, for example the images of a multimedia course. Advantageously the screen is that of a computer 11 (for example, a normal personal computer) appropriately programmed as clarified below to realize the method in accordance with the present invention. The computer 11 is advantageously equipped with means 12 for connection to a computer network 13. Again advantageously, the computer network 13 can be Internet. The connection means 12,. known in themselves, will obviously be a type suited to the particular physical connection to the netwoirk. For example in case of connection over a telephone network they will inclu.de a modem of a type known in trade. If considered necessary, the connection device "12 can also include "known cryptographic and security means for the communications . The equipment 10 includes, in addition to the computenr 11, means 60 for enabling reception from a site 50 connected over the computer network 13 of the information to be purveyed to the user, for e∑ ample the didactic content of a course. As an alternative or in addition, the information to be purveyed to the user can be local to the computear 11, for example memorized on a support such as a CDROM or a. DVD inserted in a purposeful reader with which the computer is equipped.

The equipment 10 can also include means of certification of the digital signature 14 o ± a user, means 16 of filming images of the user, and means 17 of biometric recognition of the user.

The digital signature certification means 14 of a user: can advantageously include a smart card reader 14a interf ced with the computer 11. This smart card reader 14 with, its associated smart card is already commonly used in many environments in which business or data transactions protected from computer pi-acy acts and authenticated, are required. Reading of thie smart card allows user identification after input through a computer peripheral device of the keyboard ype or similar of the personal recognition PIN delivered to the user upon acquisition of the smart card.

The equipment 10 could also interact though the network 13 with a surveillance or certification agency 90 as clarified below.

Advantageously the biometric recognition means for obtaining unequivocal identification parameters of the user could include one or more devices chosen from among a fingerprint reader, a retina reader, an iris reader, or a voice recognition device. In a preferred embodiment the biometric recognition means 17 could include a fingerprint reader 17a, also interfaced with said computer 11. The print reader could also be the known type integrated in the computer ' s mouse . It should be noted that by the term identification or biometric recognition is meant here even a simple recognition concerning the user, i.e. detecting that a user already identified remains the same during the course without thereby really identifying his true personal identity but only acquiring and comparing relative and not absolute identification parameters.

Identification of the true identity of the user could be done by other means such as the smart card reader or by insertion of the identity by an operator in charge. The equipment 10 also includes means 16 for calculating the degree of attention of the user. In a preferred form said means, realized in accordance with basically known techniques, detect the direction of the user's glance. The degree of attention is so calculated on the basis of the direction of the user's glance relative to a screen 15. The glance direction detection means can be of various known types such as, for example, a triangulation system with infrared reflection. In any case, in a preferred form they include a camera 16a that takes images of the user and processes them with known techniques by means of calculation (represented in this specific case by the same computer 11) to determine at least approximately the direction of the user's glance. The camera can also be a webcam allowing the remote agency 90 to have images of the user during the course and this might be employed to replace or complete the above mentioned user- identification. The processor realizes control means that receive user identification data from the identification means and verify that during the purveyance of information on the screen the calculated attention figure of the identified user does not fall below a predetermined minimum figure. As will be seen, various actions can be taken by the system. based on the figure taken by the degree of attention. In a preferred embodiment the control means as first operation suspend purveyance of the information to the user if the calculated attention of the user falls below the predetermined minimum level for a time longer than a predetermined maximum time. In other words, if during progress of the course the user removes his glance from the screen for a time longer than for example 30 to 60 seconds, the system suspends the course. Preferably, to be able to resume use of the course the user has to make a new detection of the biometric data and return with the glance on the screen 15. When the user has completed these operations and returns his attention to the screen, the course can be resumed. The minimum attention level can also be reached if the user glances at the screen in a zone different from that which. at that specific moment carries information that must be seen and/or learnt. Attention calculation can also have several figures and not necessarily only two, one indicating attention (looking at the screen) and one indicating total lack of attention (glance far from the screen). This can be used for example by the system to repeat part of the information shown when it is detected that the user was glancing at a point other than the screen, or to investigate information that has particularly attracted the glance of the user. The system can advantageously also include means of detection of the presence of the user before the screen. The presence detection means can be realized with the same attention calculation means 16. In particular, the camera 16a can also detect absence of the user. Absence of the user can be considered in this case in the system by assigning a minimal figure to calculation of the degree off attention. In case of detection of temporary absence, the detection means can signal to the control means the need for new verification of the identity of the user when he returns so as to ensure that the user who started the course is not replaced by another. In a simplified form of the present invention, the attention and presence calculation means of the user can be realized with the same biometric data detection means 17 and with the screen 15 by causing to appear on the screen at pseudorandom intervals the requirement for the user to authenticate himself again by biometric data detection means. If the user is distracted or even not present and does not perform authentication, after a short lapse of time the system decides that the attention level has fallen beneath the threshold and carries out the predetermined actions .

The system can also include certification means (directly at the computer 11, implemented for example by the management program or at the remote site and/or at the control agency 90) that confirm completion of the learning course part to which the information refers when the control system verifies that the user's attention has remained above the minimum level throughout purveyance of the information making up the course. Advantageously the certification means memorize the completion on the remote server through the computer connection. For example, in the case of a course for recovery of driving license points the remote server can be at the national or international agency that manages the database of the situation of the points associated with all the driving license owners. In case of professional updating courses, the server can be at the agency that manages the courses or that certifies the state of professional updating of those enrolled. With reference to FIG 2 a possible way of operation of the system is now described that can be in all or in part implemented in an appropriate computer program loaded in the system. In one embodiment, after starting, a program 70 implements (diagrammed by box 71) the operations of identification request 72 and user identity verification 73. In case of positive verification, the purveyance of a course 75 begins. During use of the course the degree of attention and the presence of the user are verified. In case of simplified detection of the degree of attention, course-stopping points 76 are had followed by a user identification request 77, forwarded after a first time-interval Ti from the start of purveyance of the courrse. In case of positive verification there is continuation 78, 79 of purveyance of the course. This stop and verify scheme is iterated for a pseudorandom number N times at time intervals of Ti, T2 up to TN, of duration also pseudorandom, so that the user is obliged to be physically present and attentive to answering promptly the questioning of recognition and verification to which the system subjects him without his being able to hide by some subterfuge . At the end of purveyance of the course, indicated by the box 80, the program 70 may fourward a request 81 for final user identification. If the end of the course is regular the program 70 completes operation 99 of memorization of completed purveyance of the course and sends the information to an appraisal and surveillance agency 90 which can thus ensure effective completion of the course by the identified user and, if required, certify it safely. In cases of failed recognition of the identity of the user (blocks 83, 84 and 85) the program 70 provides at 86 for stopping purveyance of the course, memorizes at 87 the fact of interruption, and sends it over the computer network 13 to the appraisal and surveillance agency 90. The interruption can thus be temporary or lead the program to offering the option 98 of restarting purveyance from the beginning of the course.

Requests for user identification 72 and 77 to 81 involve activation of at least one of the identification means which can be digital signature certification 14, real time image transmission 16, or biometric user-recognition 17. These means can be activated individually or in sequence or in a random correlation established by the program 70. As clarified above, instead of performing the random identification requests or in addition thereto, in its more complete embodiment the program can calculate degree of attention by using the means of detection of the direction of the user's glance to suspend the course if necessary and require a new identification.

Naturally, it can also be provided that the user could voluntarily suspend the course to resume it later. It is now clear that the preset purposes have been achieved. Thanks to the present invention the chance to follow courses is given to individual examinees when they want to and (if equipped with an apparatus in accordance with the present invention) where they want to even without hourly constraints. A simple certification system easy to apply and allowing the purveyor of the course as well as the user thereof the possibility of managing their own time and resources the best possible way is also offered.

Despite the practical nature and relatively limited cost of the system compared with conventional courses this is a simple and absolutely effective examinee-control system for times and manner of fruition of the course for an organization in charge. There is also the advantage of being able to offer the same course with the same content and the same value over a broad territory. In case of courses sent over the network the changes and updatings of a course or new courses can be purveyed with no need of any physical movement of persons or things with obvious savings and the capability of offering courses even in areas difficult to reach.

Naturally the equipment 10 can be set up not only near the individual user but also in various locations where the individual users go to follow the courses . For example in courses for recovery of driving license points it is possible to set up terminals at driving schools or licensed agencies in accordance with the present invention. The use of certified multimedia courses allows realization of a course with high computer-teaching content through the use of filmed sequences, declarations and cartoons making the content of the course more useful and readily memorizable by the user and contributing to keeping the attention level high for the entire duration of the lesson. The simplicity of the structure of the equipment 10 even allows realization of multimedia equipment for use of courses that allow following of said courses from any computer equipped only with simple means of connection to a computer network in locations that are not specially equipped. Indeed, the equipment can be readily and economically set up by using components of known type. In addition, with the present invention, equipment has been realized allowing the user to self-certify his identity in complete security to an assigned surveillance agency at any time before, during or after purveyance of the course. The equipment is simple to set up and make operative even for an inexpert user. Naturally the above description of an embodiment applying the innovative principles of the present invention is given by way of non-limiting example of said principles within the scope of the exclusive right claimed here. For example, a mixed local and remote processing system can be provided over the network during the use-detection authentication steps of the course. If the connection to a remote server is used, any connection cessations during use of the course could be made irrelevant for the regular carrying out of the course while realizing the system in such a manner that in the initial phase one proceeds for example to identity verification by using the network for connection to the central server but subsequently transferring all the control to a peripheral software that would be installed on the user's PC. The latter would then automatically unload on the central server all data referring for example to each hour of the course followed by each individual examinee while indicating the possible anomalies as "failed presence" during carrying out of the course and all the answers required in the various parts of the course.

The examinee would again connect to the network at the end of the segment of the course to declare having terminated and this would allow the system to connect to his PC by making the above described checks . Even if the examinee should not connect with the service center at the end of a segment to declare having terminated because of technical or other problems, this would not compromise control and verification by the service center, which would always do it automatically at the time the examinee connects to follow the hour or segment of the next course.
