Protractor3D: a closed-form solution to rotation-invariant 3D gestures

Abstract: Protractor 3D is a gesture recognizer that extends the 2D touch screen gesture recognizer Protractor to 3D gestures. It inherits many of Protractor's desirable properties, such as high recognition rate, low computational and low memory requirements, ease of implementation, ease of customization, and low number of required training samples. Protractor 3D is based on a closed-form solution to finding the optimal rotation angle between two gesture traces involving quaternions. It uses a nearest neighbor approach to classify input gestures. It is thus well-suited for application in resource-constrained mobile devices. We present the design of the algorithm and a study that evaluated its performance.

Method and system for processing messages within the framework of an integrated message system

Abstract: A method and system for processing messages within the framework of an integrated message system. Recipients of messages in an integrated messaging system are provided with an authentic impression of the received message. In a first step, a message received within the framework of an integrated messaging system is automatically translated. Language detection and dictation system is provided. The message contents of the incoming message as well as its segments and parameters are simultaneously utilized to generate additional information regarding the sender and the information, which is suitable to give the recipient an impression of the received message in the most authentic form possible.

From Space to Stage: How Interactive Screens Will Change Urban Life

Abstract: Framed digital displays will soon give way to walls and facades that creatively motivate individual and group interaction. A stage serves as an apt metaphor to explore the ways in which these ubiquitous screens can transform passive viewing into an involved performance.

NAT usage in residential broadband networks

Abstract: Many Internet customers use network address translation (NAT) when connecting to the Internet. To understand the extend of NAT usage and its implications, we explore NAT usage in residential broadband networks based on observations from more than 20,000 DSL lines. We present a unique approach for detecting the presence of NAT and for estimating the number of hosts connected behind a NAT gateway using IP TTLs and HTTP user-agent strings. Furthermore, we study when each of the multiple hosts behind a single NAT gateway is active. This enables us to detect simultaneous use. In addition, we evaluate the accuracy of NAT analysis techniques when fewer information is available. We find that more than 90% of DSL lines use NAT gateways to connect to the Internet and that 10% of DSL lines have multiple hosts that are active at the same time. Overall, up to 52% of lines have multiple hosts. Our findings point out that using IPs as host identifiers may introduce substantial errors and therefore should be used with caution.
