BBC: Microsoft is developing a headset designed to immerse the wearer more fully in the cyberworld. The HoloLens, currently in development, includes a holographic computer that superimposes holograms on the user’s field of view. That so-called mixed reality is supposed to “unlock all-new ways to create, communicate, work, and play,” according to the company’s website. Besides turning one’s surroundings into a giant computer screen, the device is also being equipped with a biometric data sensor system to determine whether the user is becoming stressed and then take action to help relieve that stress. One example given was of a person trying to assemble a bookcase: If the HoloLens senses that the person is becoming frustrated, it may offer up a video with step-by-step assembly instructions. However, because of the complexities involved, including how to discern stress in different individuals and how to differentiate between positive and negative stress, it may be a while after launch before this feature becomes available.
