Virtual reality has become one of the hottest new technologies. But at least some of the devices using the technology are costly. Others –- like the AirVR mount that just straps a mobile device to the user’s head –- look even less comfortable and more awkward than the bulkiest of virtual reality headsets.
Shot is an affordable lens attachment for iPhones that, combined with an accompanying app, creates virtual reality videos and photos that can be shared. The attachment easily slides onto the smartphone and is made up of its own two lenses that increase the field of view of the smartphone’s camera.

A head-up display (HUD) can be a handy device in a car, especially when facing low visibility conditions. Such devices provide valuable data for drivers and, because they display information on a transparent screen in front of the windshield, drivers don’t have to look away from the road to see that data. However, most HUDs are expensive, whether they’re purchased built into a luxury car or bought separately as an aftermarket product.
