We have developed augmented reality (AR) glasses that can be used outdoors for long periods of time. To enable this outdoor usage, both high light utilization efficiency and high transmittance are required. Polarizing beam splitter coatings with characteristics that correspond to the visible wavelength range are used to achieve 75% transmittance and 2% light utilization efficiency. In addition, it is necessary to reduce the burden on the wearer's nose to allow them to use the device for extended periods of time. The combiner and the lenses are made from plastic, and an anamorphic optical system is used in which the position of the pupil of the incident optical system differs in two cross-sections oriented perpendicular to the optical axis. As a result, the weight of the entire optical system is only 20 g for both eyes, despite the full-color imaging capability.

The learning process in humans is reinforced with feedback on actions. In sports, feedback plays an important role in optimizing motion techniques. Athletes can learn and internalize correct motion executions in order to improve their performance. The most widely used feedback method in sports is response advice by experts (coaches). Meanwhile, technical devices are useful for promoting motor learning. With the help of extended reality, such as virtual reality, augmented reality and mixed reality, it is possible to receive visual feedback through (head-mounted) displays during motion execution for real-time corrections in motor learning. The use of extended reality real-time feedback is becoming increasingly common in many application fields of motor learning. So far, forms of real-time feedback have mainly been used in the health and medical sector. In sports, the increasing exploration of real-time feedback could provide a useful supplement to conventional feedback methods. Real-time feedback using extended reality could enable a better self-motion perception and faster learning success, consequently, having a positive effect on the performance development of athletes. This article summarizes the current use of real-time feedback ( Prior application of real-time XR feedback in various research fields section), presents the useful addition of extended reality real-time feedback to common feedback methods in sports ( Framework of the addition of real-time XR feedback in sports section), and recommends a possible integration of real-time feedback in sports training with the help of a model ( Concept development section). Overall, the benefits of using extended reality technologies are presented, and a human-system-interaction in sports is proposed.
