When people typed the letters and numbers of difficult-to-read curvy and blurred text, this information was used to help digitize old, printed media that computers couldn't decipher yet. CAPTCHA, for example, had an added benefit beyond protecting websites from automated activities.
Luis von Ahn's research centered on human computation systems, a method of improving computational models by collecting data as a byproduct of someone doing something else, like playing a game. ITR awards were meant to encourage and stimulate innovative, high-risk and high-return multidisciplinary research that would help prepare Americans for the information age by extending the frontiers of information technology and improving our understanding of its impacts on society.įrom this research, von Ahn helped create reCAPTCHA, a system that anyone who uses the internet has encountered as it distinguishes between human and automated web domain access (i.e., the "Are you a robot?" question). The program was a funding priority established in the early 2000s in response to a report created by the president's Information Technology Advisory Committee. NSF supported Duolingo CEO Luis von Ahn from graduate school through his early career research as a professor at Carnegie Mellon University.Īs a doctoral student in computer science and postdoctoral researcher at Carnegie Mellon, von Ahn was supported by the Information Technology Research, or ITR, program.
