Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected.

Many industries see a big future in AR business and applications. The present research focuses on the user input performance of these AR-devices. This paper proposes an evaluation procedure using a server based input interface with a built-in assessment control. The evaluation is performed by test persons exposed to two AR devices: Microsoft Hololens and Epson Moverio BT-200. A conventional mouse input is used as a benchmark. The assessment reveals a trend of strength and weaknesses of each device and can orient developers to create more optimized AR experiences and improve the user experience.</span></p></div></div></div></div>
