Wearable Augmented Reality: An approach of Digital Reality Experience

Wearable AR is a device that can be worn by a consumer and also overlays digital information on the physical environment. It is one of the advanced and immersive technology. It has many features like Camera, Audio-Video, Wireless Connectivity, GPS Navigation, Motion Sensing, Object Tracking and many more. It is also sometimes called Wearable Computer.

The soft robots are made up of channels & chambers in an elastomer. This channel inflates by pressurization and that create motions. This motion is controlled by geometrical modifying of embedded chambers and its wall material properties. It is frequently powered by compressed air. The legs of soft gripper robots are mostly preferred in even number like 2, 4 & 6. There are a growing demand for new types of robotic end effector.

Advanced Projection Technology:
Wearable AR headsets use virtual hologram technology for the projection of digital information on the physical environment. The display used for virtual hologram projection is called Head Mounted Display.

Google Glass uses prism projection technology, a Field sequential Color LCoS display generates the graphical information and projected on a tiny semi-transparent prism that mounted on the upper right-hand side of the glass. In LCoS display the illumination of colour is rapidly passed by true red, green and blue LEDs and it will be synchronized with the switching of colour channels. The process of synchronization is so quickly that it gives a perception of continuous streaming of images in real colour to users.

While the Vuzix Blade is used waveguide optics as a projection technology. It has two waveguide solution, one for the blue-green and one for green-red portions of the visible spectrum. This waveguide approaches an input grating, it takes light from pico-projector and couples it into the waveguide. There is a section of pupil expander that takes small size images from pico-projector and enhance the size of images in front of the user.


Audio Augmented Reality:
Audio Augmented Reality is a new feature of headphones. AAR overlays an extra layer of information on the environment through sounds. It is also known as spatial audio. Bose AR is an Audio AR approach enabled with embedded motion sensors like accelerometer, gyroscope and compass that can detect head orientation, body movement and to navigate sounds. Also, its apps can use the information with location data from the smart device and offer tailored audio content.

Wearable AR is wide application-based technology. It is useful for Education, Medical, Military, Entertainment, Gaming & More. It is a digital reality experience device that combines reality and virtual world.
