Lower Limb Research Stanford Collaboration

Objective: Virtual reality has unprecedented therapeutic effects. The Lower Limb project focuses on those suffering from lower body paralysis and aims to help stimulate recovery through simulated environments.

Completed Tasks
• Infinite terrain generation tiling
• Pausing animation toggles in game
• Integrating WAV files for ambient noise
• Third person camera perspective toggling
• Automating adding files to the Oculus Go
• Adjusting camera perspectives, and angles
• Terrain creation using unity default terrain tools
• Collision detection for game objects in the environment
• Logging data to CSV for tracking head movements throughout time

IxD Box of Wonder

Objective: The purpose of this mystery box is to invoke a sense of nostalgia upon those who choose to peer into it, but it isn’t just nostalgia…it’s fear. Fear alongside anger are some of the most potent emotions human beings can feel. Fear can be petrifying, and often times entices us to behave in bizarre ways. I wanted to recreate this emotion by allowing the user to peer into the eye sockets to uncover a classic horror movie scene much to the likes of Dracula, or Frankenstein.

Operation: The front-exterior of the box is laced with laser engravings and consists of a skulls head. On the side there is a crack shaped cut out that reveals a touch sensor. Users are able to peer into the eye sockets and upon activation of the touch button are greeted by an animated horror scene.

IxD Intersect

Objective: We were given an excerpt from “There Will Come Soft Rains” and asked to create a physical manifestation of our interpretation. This project focused more on the interaction between separate systems, as opposed to the former that was limited to a singular interaction. Intersect was inspired by artist Kazimir Malevich.

Operation: There are two components to this interaction. The first box is composed of an IR sensor that measures the heat of varying objects. Depending on the level of heat emitted, the Arduino board triggers different lighting effects to the LED strips attached. The second box is comprised of a motion sensor that triggers an ultra-sonic distance sensor that measures distance by emitting a high frequency pitch that bounces off a surface to be recalculated. Different sound effects are played depending on the distances that are retrieved. The boxes are designed to work and interact with each other.

What I Learned

My experience at Cornell University has been phenomenal. Throughout the course of my first year, I have had the pleasure of being mentored by world class faculty in subject areas pertaining to business, design, and engineering. From being taught iOS development from Apple Software Engineers to Product Design from Facebook Designers, and to even have the opportunity to hear the stories of successful entrepreneur alumni has been a great blessing.

I will continue to add projects onto this page and look forward to my research with Francois Guimbretiere in the Fall.
