A3 — “Cloud-sourced” image analysis
Speaking as a photography instructor, and photographer, mobile photographic technology – in particular, the pretty decent camera attached to nearly every mobile device – has been something of a double-edged sword. On the one hand, never, ever has photography been as free, easy, convenient and accessible to so many. Keypoint Intelligence predicts that worldwide, we’ll shoot nearly […]
Am I — *cough* — sick?
You’re probably familiar with one tell-tale sign of a respiratory illness – a rough, throaty, distressed voice that can tell you when someone you’re close to is unwell (or, conversely, needs to be carefully mimicked when you call your employer to say “I…*cough*… don’t think I can come in today”). But evidently, our voices may […]
A quick and dirty introduction to QR codes
What are QR codes? A QR code (originally short for Quick Response code) is a machine-readable barcode that can be scanned and interpreted by dedicated scanners, or – more importantly to us – nearly any mobile device with a camera. Users of IOS11 or higher and some Android users will find they have native support […]
A2 — Augmented Reality
Augmented reality (AR) is precisely what it sounds like: reality, but with something added. The “something” added can include static data (a part number, an object label), dynamic data (temperature, speed), a visualization (a building design, a game character), as well as auditory, haptic or other sensory cues, seamlessly integrated into the view of the […]
On the topic of Open Education
In our study of Mobile and Open Learning, we’ve spent a lot of time considering and discussing mobile learning, but less time on the topic of open learning. The recent Moveable Feast project on MOOCs, and a subsequent post about MOOCs, reminded me that in 2013, I helped facilitate a MOOC called “Online Instruction for […]
A1 — What’s a Wordle?
It’s a simple and familiar data visualization device for interpreting and displaying text content – they’re sometimes called ‘word clouds’ or ‘tag clouds’ — such that words appearing more often in the text are reproduced with proportionally larger type and words occurring less frequently with smaller type. Typically, an algorithm will sort the words in […]
Hack your phone!
In many of my posts and comments I take a decidedly low-tech/no-tech approach to mobile technology and learning — I think the social component of mobile is more germane to its impact on teaching and learning — but sometimes more technology really is the answer. If this can come cheaply, easily and accessibly, and can […]
MANETs — Mobile Ad Hoc Networks
MANETs — Mobile Ad Hoc Networks — offer an innovative, effective way for educators and others facilitate the connection of familiar mobile technologies (typically wireless phones or laptops) into temporary, peer-to-peer networks that can be self-forming, self-healing, on-demand and independent of physical network infrastructure. The World Bank Group suggests that “More households in developing countries […]
Here I am!
Sorry to keep you all waiting! I’m Sean. Sean Gallagher, if we’re being formal, and I’m a post-secondary instructor and educator living in Toronto. My undergrad degree is in Photography — I’m sure I’ll explain at some point — but I also spent a dozen years assisting in various ways — actually, pretty much all […]
