Lightening the load of augmented reality glasses

Despite the popularity of augmented reality, AR wearable technologies haven’t gained traction due to the weight and bulk associated with batteries and electronic components, and the suboptimal computational power, battery life and brightness of the devices. A team of researchers recently improved the practicality of light-receiving AR glasses by increasing the angle of incidence light capable of producing an adequate projected AR image from five degrees to roughly 20-30 degrees.
