HDMI, VGA, Buit-In PC’s and Document Cameras. Sometimes Bluray, DVD and even VHS(!). How many ways to present content does an AV presentation system really need? If we could steal a play from the IT managers handbook and tell users, “That is not supported”, what would our systems look like? What is really the minimum requirement for the typical presenter to get their stuff onto the projection screen?
It is no secret that complicated system are more difficult to set up and maintain. Just keeping enough cables on hand for different signal types can be a challenge, never mind dealing with EDID tables and laptop settings. What would the least complicated AV presentation system look like?
The first thing to go are laptop connections. We no longer support bringing your own laptop. Presenters will need to put their content on the network and use the local PC to display it. But why stop there?
If built-in PC’s are mostly used to stream content, let’s replace them with a network stream player. And while we are at it, let’s make the IT administrators job easier too. Presenters will no longer store content on our servers, they can use something like Dropbox or Google Drive. Now we’re talking…
Using online storage services creates a new feature in our system that was previously not available – content sharing from the audience or students. In a classroom setting, giving students access to displaying content is a big security concern. But if a student shares a Dropbox file with the presenter, the presenter remains in control of what gets shown on the display. Real time sharing with this type of security is not...
Many of you who know me well may be surprised by this:
While I love being around and am fueled by the excitement and passion or others, after a day or two of this, I need my alone time to refuel. I am energized as much by my interactions with others as by my quiet time by myself, in my own head. And I NEED both. That balance is as necessary to my professional productivity as it is to my personal passions.
During three days of campus tours and meetings with various media services/ academic technologies/ instructional technologists I was contemplating my own exhaustion. It was a different type of run-down than the understandable flat out tired that comes from a week long trade show in Vegas. It was an overwhelmed type of feeling that made me want to shut down for a few hours and just be quiet. I didn’t want to shut off my brain- I wanted to contemplate my experiences and thoughts about the day in a quiet and secluded setting.
Then I started generalizing my own emotions as those of “most” other people, as we humans are so often prone to do. Our industry, our...

Just a few days ago, Apple announced the specs for its new iPhone 8 and anniversary edition iPhone X devices. Apple’s product announcements are typically highly anticipated, with many speculating about new features and technological advancements months before the formal release. This year’s event, however, seemed to have a grander, more excited energy swirling about it. The iPhone X (the ten year iPhone anniversary edition) was purported to have technology embedded that even Maxwell Smart couldn’t fathom. [Yup, I just totally impressed my Baby Boomer colleagues with that one]
Well, the official announcement, as mentioned, happened a few days ago. But the energy surrounding it hasn’t subsided. All you have to do is find any publication, website, supposed apple addict on twitter and you’ll find someone talking about it- Face ID. This facial recognition software allows a used to unlock his/her phone by simply looking at it. The 3D image processing is smart, meaning “the Bionic chip controls a Neural engine which handles up to 600 billion operations per second so it can “learn” when a user is wearing sunglasses, a hat or even grows a beard.”
I admit, even for a non-apple junkie- this is exciting, interesting and...
From Inside Higher Ed. News, May 13, 2017The past few years have proven challenging for many colleges and universities across the country. Historically, college enrollment is inversely related to the economy; as our economy (job market) improves, some colleges and universities may be seeing as much as 2-3% decline or more in enrollment. Post-secondary education is a competitive market. Where non-profit schools once spent 2% of their tuition revenue on recruiting, today many are spending 5-10 times that- a trend that began gaining steam before declining enrollment.
Schools have also been investing more in student retention. Amenities like apartment style dorms, mixed use buildings, prolific and accessible technology, community building events, gaming centers and high-end athletic facilities are used to lure students on to campus and keep them coming back. It was easy to justify these expenses when enrollment was climbing during the recession. Now, some of these projects may be held or cut as enrollment continues its trending decline.
There are, however, some areas of post-secondary education which are still growing and for which colleges and universities are spending money. Health Sciences, medicine, and STEM (science, technology, engineering and mathematics) disciplines are seeing an increase in interest and...

Until recently the cost of large flat-panels for classroom use was prohibitive, making projectors the preferred presentation technology for most colleges and universities. Now, as monitor prices continue to drop, schools are questioning their traditional or standard classroom technology. Both projectors and flat-panel displays (monitors, LED displays, TVs) are strong choices for specific types of classroom configurations, each providing benefits that can only be considered when the primary use of the room is well-defined.
Cost vs. Image Size
Above 70”, projectors offer a better value of product cost for image size. That means, in auditoriums, large classrooms, multi-purpose rooms, etc. a projector is more often the preferred technology. In smaller classrooms, conference rooms, group study spaces and in specialty environments, the cost of a flat panel is low enough and the quality is high enough that they become the best option. When calculating the total cost of ownership of a projector (TCO= product, accessories, maintenance over the lifecycle of the product), which will include screens, filters and lamps, we find that projectors are still less costly than 70”+ monitors. Simply put, when comparing cost and screen size, projectors...
The technology behind Virtual Reality is coming into its own. Students are becoming increasingly more familiar with a maturing VR through video games and inexpensive (read: accessible) tech like Google Cardboard. Now, as interest increases, many educators want to know how VR can be useful as a learning tool in the classroom.
VR as a means to promote collaboration and teamwork– allow students to problem-solve in safe and secure (and unique) environments. VR gives teachers an opportunity to engage students in any type of situation from paleontology digs to courtrooms to boardrooms and in space. Not only will students learn how to work as a team in real-life (or not so real) circumstances, but these opportunities can help promote work-force readiness in a similar manner as in-field experience.
VR gamifies curriculum– A hot trend in education now is gamification of course material. The benefits are becoming clear- increased interaction, increased engagement equals a direct correlation to retention and comprehension. Gamifying content through VR allows otherwise theoretical concepts to be manipulated into [virtually] practical knowledge. Gamification can also harness competitive personalities in a motivating and productive way.
VR for safety– Complex and potentially hazardous concepts can be staged, risk-free in...
