Take two product design guys in California, add a garage and an idea and you have Satarii - a start-up operation behind a mobile accessory for solo video shoots.
With your smartphone lodged in its pocket-size docking station, you don a small tracking device and, as you move about, the dock "swivels on its base and follows you, keeping you centre frame in the mounted camera".
The motorised unit works over a range of eight metres and keeps you in the image frame across a 180-degree span.
The system is designed for the iPhone 4 and the latest video-enabled iPod Touch, but an accessory is promised to provide a standard tripod mount to open up its potential to many more devices.
The product is still a long way short of production. The inventors have been seeking funding on the IndieGoGo site and have already raised the $20,000 they were asking for. Now it clearly needs some manufacturer muscle and investor buy-in to move it out of the hobby project area.
It could well find a niche: Peter Nowak's "shameful trinity of desires" comes to mind, but I'll leave you to figure out which of three it might best serve.
