Chalkboard/Whiteboard Based Lectures

EDUSPOT is the only product in the world capable of recording the writing on chalkboards/white boards of ANY SIZE with perfect clarity while recording classroom lectures. The writing can be as small as necessary while depicting items like symbols, subscripts, superscripts, exponents, elements of matrices, command prompts etc. and will still be rendered with magnification and perfect focus enabling them to be seen without any strain in the recording.

See video example

EDUSPOT Camera Movement

Our automated camera movement can be ported to a video-conferencing session as well, enabling a BB/WB of ANY size to be used even in a VC session. A recording of such a session is as below:

Slide Based Lectures

Slides are captured as JPEG images in our product EDUSPOT. The advantage of doing so is that text can be automatically extracted from the static images for easy random access to the points of interest by the students, saving them the effort of searching for it every time within each recording.

Data Compression

EDUSPOT software automatically compresses each recording to achieve about 220 MB per hour of recording for economic online hosting while maintaining good quality. Bandwidth requirement per stream is reduced to 350 kb/s. The resolution is reduced to 640×480 while still maintaining excellent quality.

Auto-Tracking Algorithm

When the teacher writes on the right, the camera moves to the right and zooms in. When the teacher writes to the left, the camera moves to the left and zooms in.

This is a slide-based recording. In the beginning, the camera zooms to RIGHT of the teacher since he is using his RIGHT hand to point to the words on the slide.

At 6:03, we requested him to move to the RIGHT of the slides and point to the writing with his LEFT hand. Now the camera moves to the LEFT and zooms in, as it should. This is as a result of our intelligent tracking algorithm.

Please click on Chapters to see the automatically extracted slide TITLES. Clicking on any title will cause the video to start playing from the point the slide with that slide was pushed.
Please click on Glossary to see all the words extracted from the slides and the time mark at which any slide on which that word was pushed.

Camera Zooms Before/After

Comparison with the movie industry

It is worthwhile noting that the entire movie industry employs OFFLINE recording. There
is no such thing as a live recorded movie. This is because OFFLINE recordings can be edited to remove imperfections, and the quality improved before being presented to its audience. Though it is easy to avoid editing in offline recording of lectures with EDUSPOT, significant improvement can be achieved by eliminating student noise, ability to test audio level before every recording and rerecording of lectures with significant audio problems and more relaxed recording due to the absence of a live audience – all of which are not possible with live recording. HOWEVER, EDUSPOT will work perfectly for LIVE recording as well.

Enhancement of Interactive Whiteboard based recordings

  • We send all the recordings in all the classrooms to a server so that the recordings can be found easily by /Instructor/Course/Lecture by the students.
  • Our recordings capture not only what appears on the IFP but also the instructor’s full body language.
  • Often the IWB is used in conjunction with a WB/BB to further explain topics. Ready solutions from IWB manufacturers have no way to record these. EDUSPOT records these as well with full random access.
  • The instructor can be fully mobile with 180-degree mobility and the camera follows the instructor automatically.
  • The camera zooms in automatically on the IFP through software developed by us so that writing or anything else is MAGNIFIED and clearly visible.
  • The slides are captured in JPEG form rather than as a part of the video. Slides are seen with PERFECT clarity since they are STATIC images.
  • Quick random access is possible to the POINT OF INTEREST by thumbnails of slides created by our software and by titles of the slides or by words on the slide by our automatic text extraction.
  • Auto-captioning
  • The data compression that all EDUSPOT recordings are subjected to will be useful for optimizing the cost of streaming for the student from a central server.

We just did a presentation for a very tech-savvy institution in Hyderabad which have
implemented IWB in all their classrooms.

They said EDUSPOT is useful for enhancing their implementation with features that
IWB does not offer.

Cost

The cost per classroom for the hardware is about Rs. 2.5L per classroom. We are flexible on software pricing.

Closed Caption Capability

Automatic closed caption capability is offered for all the recordings done with EDUSPOT as an option.
