Developed by computer scientists at Brown, the new software could help web developers to optimize content and make websites more user-friendly.
New software created by Brown University computer scientists could help website owners and developers easily determine what parts of a page are grabbing a user’s eye.
The software, called WebGazer.js, turns integrated computer webcams into eye-trackers that can infer where on a webpage a user is looking. The software can be added to any website with just a few lines of code and runs on the user’s browser. The user’s permission is required to access the webcam, and no video is shared. Only the location of the user’s gaze is reported back to the website in real time.
“We see this as a democratization of eye-tracking,” said Alexandra Papoutsaki, a Brown University graduate student who led the development of the software. “Anyone can add WebGazer to their site and get a much richer set of analytics compared to just tracking clicks or cursor movements.”
Papoutsaki and her colleagues will present a paper describing the software in July at the International Joint Conference on Artificial Intelligence. The software code is freely available to anyone who wants it athttp://webgazer.cs.brown.edu/.
Brown University (formally Brown University in Providence in the State of Rhode Island and Providence Plantations) is an American private Ivy League research university located in Providence, Rhode Island.
Founded in 1764 prior to American independence from the British Empire as the College in the English Colony of Rhode Island and Providence Plantations, Brown is the third oldest institution of higher education in New England and seventh oldest in the United States. The university consists of The College, Graduate School, Alpert Medical School, the School of Engineering, and the Brown University School of Public Health. Brown’s international programs are organized through the Watson Institute for International Studies.
Brown was the first college in the nation to accept students regardless of religious affiliation. Brown accepts 8.9% of undergraduate applicants, placing it among the world’s most selective universities. The New Curriculum, instituted in 1969, eliminated distribution requirements and allows any course to be taken on a satisfactory/no credit basis. In addition, there are no pluses or minuses in the letter grading system. The school has the oldest undergraduate engineering program in the Ivy League (1847).
Pembroke College, Brown’s women’s college, merged with the university in 1971. While Brown is considered a small research university with 713 full-time faculty and 1,947 graduate students, five of its professors and two of its alumni have been honored as Nobel Laureates. The faculty added 100 new professors in the past 10 years under the Boldly Brown campaign.

In a new study in mice, researchers overcame a process by which cancer co-opts a fundamental protein into protecting it against the body’s defenses.
For cancer to spread, the cells that take off into the bloodstream must find a tissue that will permit them to thrive. They don’t just go looking, though. Instead, they actively prepare the tissue, in one case by co-opting a protein that suppresses defenses the body would otherwise mount. In a new study, scientists report that by wresting back control of that protein, they could restore multiple defenses in the lungs of mice, staving off cancer’s spread there.
“Cancers are known to have the ability to co-opt or evade host anti-tumor responses,” said Dr. Jack A. Elias, dean of medicine and biological sciences at Brown University and corresponding author of the study in the Nature journal Scientific Reports.
A key protein that apparently becomes co-opted is Chitinase 3-like-1 (CHI3L1), which has a natural purpose in a wide array of organisms where it helps to fight infections and stimulates tissue healing. However, it is also susceptible to going awry where it contributes to the generation of a variety of diseases. In human diseases like idiopathic pulmonary fibrosis it mounts an overzealous response that leads to pulmonary scarring, and in diseases like asthma it sustains a harmful immune response. People have a directly analogous version of the protein called YKL-40 and, in patients with cancer, high levels of its expression correlate strongly with advanced cancer spread and a poor prognosis
A simple chemical conversion could be another step toward making cheap, efficient and stable perovskite solar cells.
Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another — a type that has better thermal stability and is a better light absorber.
The study, by researchers from Brown University, the National Renewable Energy Laboratory (NREL) and the Chinese Academy of Sciences’ Qingdao Institute of Bioenergy and Bioprocess Technology published in the Journal of the American Chemical Society, could be one more step toward bringing perovskite solar cells to the mass market.
“We’ve demonstrated a new procedure for making solar cells that can be more stable at moderate temperatures than the perovskite solar cells that most people are making currently,” said Nitin Padture, professor in Brown’s School of Engineering, director of Brown’s Institute for Molecular and Nanoscale Innovation, and the senior co-author of the new paper. “The technique is simple and has the potential to be scaled up, which overcomes a real bottleneck in perovskite research at the moment.”
