Human Computer Interaction

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.

We propose ways to increase the displayed image pixel resolution without having to manufacture any additional pixels, while at the same time maintaining full-color 24-bit images.

We present a VR360° video player with haptic feedback playback.

In this work a general circuit model for the cavity resonant wireless power system is introduced and validated against simulated and measured results.
