Dartmouth Professors win $100K Microsoft Hololens grant

A team of Dartmouth Professors (Emily Cooper from PBS and Wojciech Jarosz and Xing-Dong Yang from CS) win the highly competitive Microsoft HoloLens Research Grant. Their winning proposal, entitled "Augmenting Reality for the Visually Impaired with Microsoft HoloLens”, will investigate ways that augmented reality devices like the HoloLens can aid the visually impaired in their day-to-day tasks. See more details about all the winners at Microsoft's blog or at Engadget.

Can Your Smartphone Predict Your GPA?

 

Many cognitive, behavioral, and environmental factors impact student learning during college. The SmartGPA app uses passive sensing data and self-reports from students’ smartphones to understand individual behavioral differences between high and low performers during a single 10-week term.

The research team show that there are a number of important behavioral factors automatically inferred from smartphones that significantly correlate with term and cumulative GPA, including time series analysis of activity, conversational interaction, mobility, class attendance, studying, and partying.

DartNets Lab's HiLight System Won Best Demo at MobiSys'15

HiLight is the first system that allows screens (e.g., screens of TVs, laptops, tablets, or smartphones) to talk to camera-equipped devices without you knowing it, regardless of the content shown on the screen. It works even upon the dynamic screen content generated on the fly by user interactions (e.g., gaming, web browsing). It removes the need of showing the gangly barcodes (e.g, QR codes) on the screen, so that the screen can display the content as it normally does, while the communication happens behind the scene, in real time.

This work was presented and demoed at the ACM MobiSys'15 on May 20, in Florence, Italy. It won the Best Demo Award.

Dartmouth Readies Students for Cybersecurity Challenges

There are approximately 3.5 billion devices in the U.S. today connected through the Internet—smartphones, laptops, tablets, servers—and by 2020 there will be 45 billion, predicts William Nisen, associate director of the Institute for Security, Technology, and Society (ISTS) at Dartmouth.

“We are going to have machines talking to machines without human intervention, and unless we get the security right we are going to wind up with a huge problem,” he says.

“Today there are about 2 million correctly certified web servers on the Internet, but we don’t have a fully effective way to tell it’s really ‘Amazon’ on the other end,” says ISTS Director Sean Smith. “What will happen when the number of these things increases a thousand-fold?”

Computational Design of a "Rocker" Protein Cracks a Decades-old Puzzle

Human cells are protected by a largely impenetrable molecular membrane, but Prof. Gevorg Grigoryan, with a team of collaborators, have built the first artificial transporter protein that carries individual atoms across membranes, opening the possibility of engineering a new class of smart molecules with applications in fields as wide ranging as nanotechnology and medicine. This work, which appeared in the journal Science, is a milestone in designing and understanding membrane proteins. The study was a collaboration between researchers across different universities: Dartmouth's Gevorg Grigoryan,  MIT's Mei Hong, fellow University of California, San Francisco investigators William F. DeGrado and Michael Grabe, and others.

Emily Whiting at TED-x-BeaconStreet

TEDxBeaconStreet gathers a group of thought leaders from a variety of fields to share their intriguing, actionable ideas. This November, Assistant Professor Emily Whiting spoke about her work in the emerging field of computational fabrication. 3D printers are revolutionizing the manufacturing and design industry, allowing us to create shapes of astounding complexity and precision. Emily Whiting explains that the power of digital fabrication goes beyond looks; an untapped potential exists to design not just the shape, but the physical behavior of 3D printed objects. The key is the unprecedented ability to create intricate, hidden interior structures. Prof. Whiting describes how computational methods can exploit fundamental principles of physics to produce these structures, changing the way we design for the world of digital fabrication and helping us re-imagine everyday objects.

Researchers Create New Intelligent Software

Computer scientists at Dartmouth have created artificial intelligence software that uses photos, instead of just text, to locate documents on the Internet, reports The Economic Times.

“By studying results from text-based image search engines, the software recognizes the pixels associated with a search phrase and applies them to other photos without tags or captions, locating them more accurately,” the newspaper explains .

Lorenzo Torresani, an associate professor of computer science and co-author of the study, says that “modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search.”
