Theres always something happening Wednesday evenings in the Tetherless World! TWed Talk: Weds, 22 Oct (7p, Winslow 1140) TITLE: UbiKeyboard: Using sensors and muscle memory to eliminate physical keyboards LEADER: Yu Momo Chen Please join us this Wed (22 Oct) as Tetherless Ph.D. student Yu Momo Chen leads us in a discussion and (possible) LIVE DEMO of some extraordinarily cool work he has been involved with in advancing gestural input technology. ABSTRACT: As wrist-worn motion sensors become increasingly common, the opportunities for gestural input techniques, in particular the input of natural language text, have become increasingly compelling. In this paper, we present the design, implementation and evaluation of UbiKeyboard, a novel data glove which enables one-handed typing by means of inertial sensors alone. UbiKeyboard takes advantage of the fact that frequent users of a simple keyboard such as a telephone-style keypad have committed the layout to muscle memory and are able to type by touch. By tracking the relative position of the hand as it moves from memorized key to key, our system is able to do away with the physical keyboard entirely, responding to characters typed upon an imaginary keyboard within any flat, level surface. Accurate recognition of words and phrases is facilitated by the use of a language model trained on a large corpus. We have demonstrated 72% accuracy for input of individual words and 53% accuracy for input of full sentences by trained users, sufficient for supporting a variety of real- world applications. BIOGRAPHY: Yu Chen is a fourth-year PhD student in Computer Science. His interests includes mobile sensor data analysis and context modeling using a combination of techniques such as machine learning, signal processing, language modeling etc. ==== TWed Logistics (Fall 2014): * TWed schedule: tw.rpi.edu/web/twed#schedule * 7p-8p, 1st floor Winslow (1140) * We try to alternate TWed Talks with TWed Hackspaces. The alternating pattern of TWed Talks and TWed Hackspaces may off due to leader availability and Institute scheduling. * Pizza or snacks will be provided for TWed Talks * Live video streams of TWed Talks will usually be available via ustream * An archive of past TWed Talks are also available on ustream. Direct links can be found in the schedule (below) * TWed Talks from previous terms are archived; topical archive coming soon! ==== About TWed: * TWed is the Tetherless World Educational Series * TWed Talks are informal overview talks and tutorials on topics of interest to the Tetherless World community. TWed gives members of the lab the chance to share tools and expertise. TWed talks are not lectures; they are expected to be highly interactive and fun. TWed leaders are encouraged to include live hack activities in their session plans. * TWed Hackspaces during the TWed time are informal group work sessions inspired by the Hackerspace movement. This is a time when TWC people will be around and you can rely on the right people being available to answer your questions and help with your hacks. This is also a great opportunity for project teams to hack together on problems, with the knowledge and resources of TWC surrounding you.
