On first seeing this video, I have a few questions about how practical this technology is, or how useful it would actually end up being. Sure, having a screen projected onto your wrist is awesome, but how well does it work in bright environments, and how long does the battery last? It would also appear that there is no face to the watch, so you can literally only use it in projection mode. Lastly, (I’ll stop being so critical soon) you have to tilt your wrist up to allow the projection to work, which kind of seems like a fast track to carpal tunnel syndrome.
Anyway, I know it doesn’t sound like it, but this smartwatch seems like it would be pretty awesome to own. Once you make it over what may be the annoying quirks, having a tiny little projector can end up being very useful in your daily life. Imagine being able to watch those Youtube videos on a huge projection screen wherever you are. By far the coolest feature in my opinion that this watch has is the ability to project maps and directions onto your car’s windshield. Having a ‘holographic’ display feature makes this watch seem a little more worth it.
