Human Computer Interaction

In this work, we leverage advances in semiconductor optics, RF antenna design and system integration to create a hybrid RFID reader and smart LED lamp, in the form factor of a standard light bulb.

A 144 fps transparent LCD panel is used in conjunction with a transparent backlight, controllably diffusive smartglass screen, and optional switching background lighting

The Switching Dual Layer Display with a Dynamic LCD Mask is a multi-layer three-dimensional display capable of independent layer content and occlusion between layers.

We use a transparent LCD panel as a programmable dynamic mask.

We design and demonstrate a four-lens folded optical cloak and a three-lens inverted cloak with an erecting prism.

We create a solution for multi-user interactions in AR/MR, where a group can share the same augmented environment with any computer generated (CG) asset and interact in a shared story sequence through a third-person POV.

The goal of this work is to enable the ubiquitous deployment of ultra-low power nodes that communicate via ambient backscatter to wired Universal Backscatter Readers, in real-world environments.

We demonstrate applications of a new actuator, the Haplug, in dynamic virtual environments.

We demonstrate selective focusing of electromagnetic energy via electromagnetic time reversal in the near field of a metamaterial.
