Abstract

A system for recording a musical instrument performance, comprising a display screen, a video recording system to record a student, analysing means, displaying means, and a processor. The analysing means checks the ambient light level and warns when insufficient light is present, i.e. the environment is too dim. The displaying means displays images on the screen while recording, the images being sheet music, theory questions, or an automated examiner. The processor receives a copy of the recorded video and transmits it to be marked. Also provided is a complementary examiner system for performing an accredited examination on a musical instrument, including means for ensuring video playback with simultaneous display of a marking template, and means for inputting data to the marking template, and means for transmitting the marking template and video recording to a server of a certification body.

Description

ONLINE MUSIC EXAMINATION SYSTEM
This invention relates to the field of music examinations. In particular it represents an online system that enables students to sit music examinations whilst ensuring that the strict criteria set out by the UK and European governments for accreditation are met.
This is achieved through provision of system with a live video recording platform and in which all data is stored and processed in a digital format throughout. This extends to the final result of a digital UK and European approved certificate. The system is built up using a combination of pre-existing digital platforms that have been reprogrammed to overcome issues in quality standards, which would have otherwise have made the process unaccreditable, and newly-developed programs. The system is developed with application programming interfaces (APIs) that, when combined, allow accuracy and due diligence in the examination process, overcoming inaccuracies in current marking standards and increasing the speed of conversion.
The invention will now be described, by way of example only, and with reference to the accompanying drawings, in which: Figure 1 is an overview of the system, showing an exemplary arrangement of applications in an online embodiment; Figures 2a to 2c show examples of screen images displayed by the FPS checker app; Figure 3 shows an example of a screen display with automated examiner; Figures 4 and 5 illustrate examples of screen displays of sheet music; -2 Figure 6 is an exemplary screen display of multiple choice questions relating to music theory; Figure 7 is an exemplary screen display showing the status of a selection of examinations in progress; Figures 8a to 8g are sample displays of an examiner's marking area showing use and layout of a marking template; Figure 9a is a sample display for review by a moderator of the examination; and Figure 9b is an example of information presented to a student regarding 10 examination progress.
With reference to Figure 1, the system comprises a number of modules that are variously disposed on: a student-side platform; a central server, with access to a data store that may be on-or off-site; an examiner-side platform and a server of an award or accrediting body. Both the exam iner-and student-side platforms include display screens used in the examination procedure and on which information relating to the progress of the examination is displayed. Information is transmitted to and from each component under control of the central server.
The particular function that is carried out by each program module will now be described.
1. The FPS checker In preparation for taking the exam, a student will first set up a camera to start a live video recording during the course of the examination procedure. The FPS (frames per second) checker connects to the live video recording feed. Prior to the live video link being activated, the student selects an "FPS checker" icon on the student-side display -3 screen. From video data collected via the camera, the FPS checker extracts information relating to the illumination levels in the student's environment and checks that this meets certain pre-defined criteria. If the light is insufficient, the FPS checker prevents activation of the video link to the central server and informs the student, for example by displaying a message such as "The lighting quality is insufficient, adjust your lighting to be able to record." Following this prompt to the student, the FPS checker continues to monitor environmental lighting in real time via the camera's detector. If the adjustments made by the student improve lighting to the extent that the level is suitable for the examination, the FPS checker will immediately alert the student, for example by displaying a message such as "The lighting quality is good, you may now take your exam", and allow activation of the video link that enables recording of the camera image. The student will now be able to select a "record" icon and start recording their examination.
Although poor light quality reduces the bit rate of the data stream and therefore image resolution, the consequences for the music exam relate more to the audio signal that accompanies the video signal.
Poor light quality in a live internet video feed is a cause of delayed audio signal, which in turn creates an 'out of sync' video feed between the visual and the audio. For a music examination, in which the examiner is required to relate the sound quality with a musician's timing and technique, such a delay would make it virtually impossible to mark accurately.
Images displayed as the FPS checker is running are shown in Figures 2a to 2c. -4
2. The Al (artificial intelligence) examiner The Al app is configured to co exist with the live recording platform. Upon recording, an automated examiner will start communicating audibly to the student requesting random sections of pre-learned music. This program has been connected to the live recording platform to ensure that the student is in visual when being asked what to perform.
In prior art systems, the student is only able to take an online test when connection to a live feed of an examiner. This requires not only a set time for the test but also establishment of a communication link between examiner and student. Link quality is often unpredictable and, even if it can be maintained, information is too easily misheard. Use of an automated examiner (see Figure 3) allows the student to take the exam at any time, convenient only to themselves. It avoids the need for a communication link. Finally, it also avoids one potential option for cheating: a human examiner may know the student and, with foreknowledge of predefined exam questions, may alert the student.
3. Pop up sheet music app The pop up sheet music app is also configured to co-exist with the live recording platform. When the student has pressed record to commence the exam, the examiner will, in certain parts of the exam, ask for a known piece of music to be played by the student. This may, for example, be a series of scales, as shown in Figure 4. This app is connected to the live recording feed platform using a 'maximising size' code, enabling the student to see the music on screen while they play. With the recording camera also located on the screen, the student will remain clearly in visual while playing this piece of music.
In prior art systems in which music is not able to be displayed on the screen, the student must have their music in hardcopy in front of them. This not only requires the student to look away from the recording camera, but the music sheet may partially obstruct the live camera feed. Given the potential for exam aids or answer to be hidden in the obstruction, this would void the exam and, in turn, any online accreditation system. There is also an environmental advantage: no need to print music.
4. Randomised pop up sheet music app and timer app The pop up sheet music app described above is configured to display a known piece of music to the student. At a different part of the music exam, the student is required to perform a sight reading test. That is, one in which the student is required to play a previously-unseen piece of music. The pop up sheet music app may therefore also be configured to display a pre existing sheet music that has not been seen by the student and is selected randomly by computer automatic generation. In an alternative embodiment a separate app may be used to display randomised sheet music. In either case, the pop up sheet music app is configured to work with a timer app. The timer ensures that the randomised sheet music is displayed during the student's live video feed for a limited time period only. In practice, the Al examiner will alert the student to their sight reading task, the sheet music will pop up on the screen. The new 'timer' app is combined with the randomised pop up sheet music app such that the 'timer' app will show the student a countdown within a predetermined time frame. As the timer reaches '0', the randomised pop up sheet music app removes the sheet music. A sample piece of sheet music displayed on a screen is shown in Figure 5.
In the past it has proved very difficult to implement an online sight reading test. The purpose of the test is to check the student's ability to play a piece of music within approximately 30 seconds of it first being seen. It is therefore very important to control the timeframe during which the sheet music is displayed. The integration of timer app with one that displays sheet music on screen overcomes the difficulties of conducting an online sight reading test. In some prior art systems, the student is able to see the music for longer, unchecked. Such an examination therefore cannot be accredited. In other systems, the student has to turn their camera around with one hand such that the student's screen is visible to a live examiner on the other end of the feed. The examiner then takes the student through steps to access a piece of music through email or online, using a separate program.
5. Theory examination app This app combines a randomised questions app with an automatic marking app, which are used in conjunction with the timer app. Music examinations will often include an element of music theory. The theory examination app therefore includes a database of theory questions, each of which is associated with predefined and verified answers. For this part of the exam, the student is presented with a series of randomly-selected theory questions from the database. The student's answer to each is input through a computer keyboard. The Timer app is applied to ensure that the theory exam stops when the time limit is reached. The student's responses are automatically marked, for accuracy. This overcomes inaccuracies in human marking and also reduces total exam marking time. The timer app overcomes the potential for students to cheat using other programs as the timer has a predefined time limit.
An exemplary screen display of the theory examination app is shown in Figure 6. -7
6. Examiner platform All videos and marks from the theory exam apps are passed to the examiner platform for marking. The marking area page is laid out (see Figure 7) so that the examiner can simply click from video to video.
Within video playback, the examiner can pause and replay any pads of the video, which enables marking to be conducted in a controlled time frame and environment. This overcomes the current problem faced by examiners of how to keep watching the student whilst writing their comments. Too often the examiner misses valuable information on a students technical abilities when their attention is focused on writing.
7. Semi-automated Marking sheet app In the examiner platform is the marking template app, which allows the examiner to review student videos (see Figure 8b) whilst assessing and marking the performance. The marking template app is connected at one end to the automatic marking theory page and is configured to place the theory mark automatically into the Marking template (see Figure 8d).
As shown in Figures 8a and 8b, the marking template is sectioned into disciplines (shown enlarged in Figure 8e) and is not marked through words but only through a unique points system. This enables an automatic points total to be calculated at the end (see Figure 8g). Each point is also assigned a percentage out of 100 and is colour coded for ease of reading. The key used in the templates of Figures 8a and 8b is shown in Figure 8c.
As shown in Figure 8f, as each aspect within the template is graded, the grade awarded is associated with a response sheet in which comments are automatically associated with that grade. This enables constructive criticism to be given by the examiner without requiring specific language communication and handwriting skills.
8. Accreditation API Once the exam has been graded, the examiner indicates completion by, for example, selection of a button that says 'Submit grades'. This then sends an API to an OFQUAL awarded body server which then adds the student to their system. The Awarding body are then able to moderate the exam, also online. This makes the process much quicker and more efficient then the current system of sending the paperwork to another department.
Once the moderators are satisfied and the marks approved, they indicate this to the system by, for example, selection of an approval button, as shown in Figure 9a. On selection of this button, the API at the awarding body's side is triggered to produce a digital certificate that is sent to the student's online account immediately. This API is configured to read the student's name and date of birth from their account with the system. It will also automatically produce the qualification number and attach this to the certificate. The certificate is issued with a QR code for security. The QR code is scanned to direct a browser to the government RITS site, with the students name and the qualification they obtained. This guards against the possibility of students forging a certificate. A new QR code is generated automatically for every student and for each grade that they take. The API approval button allows moderation to happen quickly and automatically.
Figure 9b shows a display available to the student via their personal account in which information is collated from the server regarding past and current examination achievement.
