ReTrack: Replay Your Ride in 3D…

This is quite some concept that is seeking a little extra funding to get underway. With ride logging becoming something of an obsession with modern mountain bikers (how many group rides have you seen/been on with more than one GoPro in the crowd..?) this could be the next step. But will it take off and is there really a need for 3D ride modelling? Have a read of the information below and feel free to share your opinion as well as your money through ReTrack’s Kickstarter page…

New UK startup seeks crowdfunding for innovative gadget that replays your ride as a 3D  animation on your smartphone

ReTrack is a cunning new ride tracking and replay gadget invented by mountain biker (and, handily, satellite control software engineer) Simon Fowler. He wanted a way to replay his rides that gave more depth than a GPS trace but without the hassle of editing stacks of helmet camera footage.

ReTrack works in an entirely different way from conventional trackers. The ReTrack sensor sits on your helmet and contains high-resolution inertial sensors to track your movements – how far you’re leaning, the angle at which you’re climbing or descending, lateral acceleration and so on. The sensor communicates over Bluetooth with your smartphone for GPS data and storage.

Once you’ve finished riding, all the information can be uploaded to ReTrack’s server, where a set of unique algorithms builds a complete virtual representation of your ride that can be viewed from any angle. ReTrack will automatically create a highlights package for you, showing your ride as if from fixed cameras by the trail, tracking cameras alongside and even helicopter views. If you wanted to make a video with that kind of variety, you’d need a full film crew, loads of kit and about a week. With ReTrack, you just need to push a couple of buttons.

Over the last two years, ReTrack has been developed into a working prototype, proving that the technology works. Patents are pending, and the next step is to move it to a final, production-ready state. That’ll need six months and the support of other mountain bikers – ReTrack is using crowdfunding platform Kickstarter to raise the cash. The main reward on offer is one of the first batch of production sensors, at prices from £99 – a significant discount on the retail price. That includes free lifetime access to the service and apps, with sensors being delivered early in 2014.
