Recently, a new Microsoft patent titled ‘Wearable display device calibration’ was published by USPTO. This patent is trying proposing a method to calibrate a wearable display device. A challenge to the implementation of wearable display devices, such as a head-mounted display (HMD), for augmented reality is maintaining the alignment of the two, independent left display lens system and right display lens system of a wearable display device. For binocular viewing systems, such as a wearable display device (e.g., glasses or a head-mounted display), the left and right display lens systems generate independent images of the same view. If the left and right display lens systems are not properly aligned so that the left and right images are projected directly one over the other, then the user’s view will appear blurry. This is particularly noticeable for a vertical misalignment of the images, whereas a person’s eyes can adjust to correct for ...

A Microsoft patent filed back in December today became public which is titled “AUTO-STEREOSCOPIC AUGMENTED REALITY DISPLAY”. Microsoft describes that tablets, handheld devices and other computing devices can be included with this AR display technology. The main thing here is that the display will include see-through wave guide built using switchable diffractive elements such as SBGs. Using this technology, a virtual image that is generated as a near display object can be made to appear in a distance in AR environment. It is achieved by displaying two different images to left and right eyes, so avoiding the special needs of a additional 3D wear. Abstract: In embodiments of an auto-stereoscopic augmented reality display, the display device is implemented with an imaging structure that includes a waveguide for see-through viewing of an environment. The waveguide also transmits light of a virtual image that is generated as a near-display object to appear ...

Recently, we covered a key patent Microsoft filed for its eye-wear represented in the patent application as before. According to leaked Xbox documents, Microsoft is expected to reveal their AR glasses for games this year. We didn’t hear anything from Microsoft on this front from E3, so there is a possibility that the project got delayed due to some reasons. Today, WPDang reported that Microsoft’s augmented reality project is currently put on hold. According to their sources, the issue is related to patent licensing. The key patents related to Kinect sensor are limited to their current purpose and cannot be used for these glasses. Bing translated content from WPDang, But recently, the WPDang learned through their own channels, users who expect the Xbox virtual glasses may be disappointed. In current Microsoft Xbox team‘s internal plans, has canceled plans to the glasses, actually related development and without any problem, the main ...
