I spent last week at the annual Intel International Science and Engineering Fair (ISEF) in Phoenix, Ariz. There were over 1,800 students from around the world competing for top honors. I was there with the two finalists from the Mercer Science and Engineering Fair. Sonja Michaluk earned a 4th Place award in Earth and Environmental Sciences.
I got to check out the projects at the open house on Thursday and was as impressed as ever before. The projects were varied and sophisticated, with most doing grad-school-quality projects. I will be highlighting more in the future, but here are two along with the top winners.
The team of Iam Langleben and Liana Martins-Medina presented their project entitled The Fifth Sense, A Novel Aid Device for Visually Impaired People, Translating Computer Vision into Surround Sound for Obstacle Detection (SOFT044T) (Fig. 1). They developed their own 3D vision system that generated the data to detect obstacles. This information was then turned into tones presented using a surround-sound system.

I tried out the system that used a conventional set of headphones driven by the microcontroller-based system. The depth map started with a VGA resolution and was scaled to an 8 × 6 depth map. The challenge they encountered was that surround sound and the human ear does a good job of horizontal dispersion, but not as much in the vertical space. This lets someone easily hear about a tone noting an object in front or two on one side, but not how high it might be.
After a little discussion, we decided that a melodic tone from a low to high note could provide additional vertical information. It sounded, pun intended, like a good idea for future research. However, they asked me to wait while they edited their Python code. In a few minutes, they had the changes made and I was able to easily detect when an object might be down low, up high, or something like a wall via a glissando. That was rather impressive.
I also stopped by to chat with Ari Joseph Firester, who attends Hunter College High School in New York, N.Y. His project, WormBot: Mimicking Earthworm Locomotion (ROBO053), was the recipient of the IEEE Foundation Presidents' Scholarship Award of $10,000 (Fig. 2). The modular, flexible robot has retractable claws that move it forward. Ari used pneumatics to power the robot; each module had eight claws. Air pressure also provided feedback in addition to powering the system.

The top awards went to Allison Jia, Krithik Ramesh, and Rachel Seevers (Fig. 3). Krithik Ramesh, of Greenwood Village, Colorado, was awarded the Gordon E. Moore Award for developing a machine-learning technology for orthopedic surgeons. The project helps orthopedic surgeons achieve greater accuracy for screw placement during spinal surgery. The method has the potential to decrease operating time by at least 30 minutes, reducing physical-therapy recovery time by four weeks and minimizing negative side effects associated with traditional medical imaging.

Allison Jia of San Jose, Calif., and Rachel Seevers of Lexington, Ky., received the two Intel Foundation Young Scientist Awards. Allison Jia investigated toxic tau protein aggregates that spread in neurons in the human brain and are associated with neurodegenerative diseases such as Alzheimer’s.
Rachel Seevers designed and built a rigid, energy-efficient prototype of an underwater propulsion device that mimics the way jellyfish move through the water. Her project is entitled Bioinspired Submersible Dual Propulsion System: A Novel Approach to Ultra-Efficient Submarine Propulsion Utilizing Starting and Stopping Vortex Rings Mirroring Jellyfish Motion (ENMC025) (Fig. 4).

Shriya Reddy, of Northville, Mich., received the new Craig R. Barrett Award for Innovation. Craig Barrett, former CEO and Chairman of the board at Intel, was on hand to present the award to Shriya. Her project used a noninvasive approach for rapidly diagnosing melanoma lesions.
