Low tech video conferencing suite

May 15th, 2011 by Graham Attwell

Lst week I was aksed to provide video conferencing services for a meeting of the board of the European Educational Research Association’s Vocational Education and Training Network (VETNET).

The long running network has members from some nine different countries, but very limited funding. Six people were able to make it to Bremen for the face to face meetiong, another six wanted to particpate remotely in the meeting.

We experimented with a video conferencing link up last year, using the free UK Open Univerisity Flash Meeting and providing a link from the face to face meeting through a Panaosnic camcorder. This year was harder as I have managed to lose the power lead for the Panasonic, not realising until it was too late to get a replacement.

So I ended up using my Blue Snowball USB microphone for audio, set to 360 degrees, and a Logitech webcam, taped to a light stand and a data projector for those participating face to face.

This was all looking good, except that the camera was picking up the light, and adjusting the lense so that paradoxically the room appeared underlit. A couple of hastily borrowed desk lamps solved that problem.

And the the whole set up worked fine. The key part of the technology was the microphone. With video conferencing you can get away with poor quality video, but clear audio is vital. Also, higher quality microphones allow reasonably loud speaker playback in the face to face part of the meeting, without the risk of feedback. Other than that, having two moderators for the meeting is useful, one to moderate the face to face part of the meeting and the other moderating the online participation. Of course one person can do both, but it soon becomes very tiring.

All of which goes to show that you do not need expensive video confercing suites to effectively communicate on a remote basis. Flash Meeting works very well, and with a good USB microphone (cost about 90 Euro) and a standard webcam you are away and running.

    News Bites

    Teenagers online in the USA

    According to Pew Internet 95% of teenagers in the USA now report they have a smartphone or access to one. These mobile connections are in turn fueling more-persistent online activities: 45% of teens now say they are online on a near-constant basis.

    Roughly half (51%) of 13 to 17 year olds say they use Facebook, notably lower than the shares who use YouTube, Instagram or Snapchat.

    The survey also finds there is no clear consensus among teens about the effect that social media has on the lives of young people today. Minorities of teens describe that effect as mostly positive (31%) or mostly negative (24%), but the largest share (45%) says that effect has been neither positive nor negative.


    Robots to help learning

    The TES reports on a project that uses robots to help children in hospital take part in lessons and return to school has received funding from the UK Department for Education.

    TES says “The robot-based project will be led by medical AP provider Hospital and Outreach Education, backed by £544,143 of government money.

    Under the scheme, 90 “tele-visual” robots will be placed in schools and AP providers around the country to allow virtual lessons.

    The robot, called AV1, acts as an avatar for children with long-term illnesses so they can take part in class and communicate with friends.

    Controlling the robot remotely via an iPad, the child can see and hear their teacher and classmates, rotating the robot’s head to get a 360-degree view of the class.

    It is hoped the scheme will help children in hospital to feel less isolated and return to school more smoothly.”


    Gutenburg

    According to developer Gary Pendergast, WordPress 5, Gutenberg, is nearing release.

    Pendergast says: “As the WordPress community, we have an extraordinary opportunity to shape the future of web development. By drawing on the past experiences of WordPress, the boundless variety and creativity found in the WordPress ecosystem, and modern practices that we can adopt from many different places in the wider software world, we can create a future defined by its simplicity, its user friendliness, and its diversity.”


    Adult Education in Wales

    Learning and Work Institute is organising this year’s adult learning conference in partnership with the Adult Learning Partnership Wales. It will take place on Wednesday, 16 May 2018 at the Cardiff City Stadium.

    They say “Changing demographics and a changing economy requires us to re-think our approach to the delivery of learning and skills for adults. What works and what needs to change in terms of policy and practice?

    The conference will seek to debate how can we respond to need, grow participation, improve and measure outcomes for citizens, and revitalise community education.”
