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 ...

Recently, we have been reporting about number of patents related to Augmented Reality glasses by Microsoft. Today, we came across another one which describes a technology to protect the wearer’s eyes. Wearer’s eyes need to be protected from too much light from the display. The brightness of the display is a combination of how much external light gets through the display and how much light is being used to display images. Thus, if too much external light shines through the display the user may experience eye damage or discomfort. Also, if too much light is used to display images, the user may suffer eye discomfort or damage. Read the abstract below on how Microsoft’s tries to solve this issue. Abstract: The technology provides various embodiments for controlling brightness of a see-through, near-eye mixed display device based on light intensity of what the user is gazing at. The opacity of the ...
