Augmented Reality

The augmented reality research group is directed by Dr. William Hoff. Augmented reality is the process of augmenting the user's view of the real world with computer-generated sensory information in the form of graphics (although sound can also be used). It is different from virtual reality, which completely replaces the user's view of the real world with a simulated one. In AR, the user still sees the real world but the world is enhanced (or augmented) by virtual objects. For displaying the information, a head-mounted display can be used. More commonly, a hand-held device such as a smart phone or tablet is used. Virtual objects are overlaid on the live video images coming from the device's camera.

A critical component in augmented reality is sensing the real world, in terms of recognizing objects and estimating the position and orientation (pose) of the user's display relative to the real world. This information is critical in accurately rendering the virtual objects such that they are aligned with the real world. Another critical component is to automatically learn a model of the task being performed (such as a maintenance or assembly task) and recognize the state of the user’s progress through the task, in order to give guidance.
