Tracking

It's definitely annoying when you're trying to swat a mosquito that's flying around a room, but you lose track of where it is. Bzigo is designed to help, as it optically-tracks mozzies and then highlights them with an eye-safe laser.

Although many scuba divers utilize wearable computers to track dive stats, those devices can't record an actual map of the underwater route that the user travelled. The newly-developed Brizo, however, is claimed to do exactly that.

Being a college lecturer – or at least, being a good one – involves more than just speaking at a podium. You also have to engage the students, and a new dual-camera system is designed to assess just how well instructors are doing so.

Getting real, physical movements accurately depicted in the digital world remains a challenge for programmers and engineers, but a newly developed glove promises to advance the tech significantly. It's able to capture hand movements with much more detail and nuance than most existing solutions.

No-one likes to queue at airport check-in lines, it eats into your holiday time, and can be both boring and tiring. Now British Airways has signed up for ViewTags, reusable electronic baggage tags that can be attached to luggage before holiday-makers get to the airport.

Many mountain bikers already use smartphone apps to track basic ride metrics such as route/distance travelled, elevation gain, and speed. A group of four Danish cyclists wanted to take things significantly further, however, so they created TrailSense.

​If you're managing security at an outdoor event, then it's important that you know where all of your staff are. A system developed at Germany's Fraunhofer Institute for Applied Information Technology is designed to let users do just that, and it doesn't require a mobile phone network.

​There are already swim-tracking wearables such as watches, that track data such as the number of lengths swum. TritonWear is taking things further, however, with its just-announced Triton 2 – the device tracks 13 swimming metrics at once, transmitting data in real time for performance analysis.

Mimic Go might look like a bubbly, chubby-version of a tracking tag (which it is) but that's only one of the tricks it has up its red, plastic sleeve. The Mimic Go can help prevent things from going missing in the first place. And light up your ride.
