Department of Computer Science: Xing-Dong Yang

Description

Xing-Dong Yang, assistant professor of computer science at Dartmouth College, will give a talk entitled "Interactive Systems for 'Smart Things' with Better Sensing, UI, and Low Energy Consumption" for the Department of Computer Science.

Refreshments will be served starting at 10:30 a.m.

Abstract:

Interactive devices are an essential component of any computing system. However, those that are widely used today (e.g., a touchscreen) do not fit well with the new forms of computing in the era of "smart things" and beyond, where computing is no longer restricted to a square machine or flat surface but is instead carried out on smart everyday "things" (curved or flat, soft or rigid) that are at home, at a workspace, or worn on the body. As such, new interactive devices and software systems need to be developed to allow a wide adoption of this technology for significant societal benefits.

In this talk, I will present three projects to exemplify our efforts in this space by demonstrating our approaches to overcome some of the major challenges we are facing in hardware (e.g., sensing), software (e.g., user interface), and energy consumption. For sensing, I will present a soft sensor, developed for contextual interactions on interactive fabrics based on the precise detection and recognition of conductive objects that are commonly found in households and workplaces. For user interface, I will introduce an on-fingertip keyboard, optimized for eyes-free typing using micro finger gestures. For energy consumption, I will present a self-powered module for gesture recognition that utilizes solar cells for both energy harvesting and gesture sensing. I will also describe the visions behind these three lines of research.
