Enhancing Haptic experience

Recent advances in man-machine interaction, telerobotics, telepresence and teleaction have shown that introducing the haptic modality to multimedia applications has the power to significantly widen their application range and to dramatically improve the user experience. Especially, the human body surface has been considered as an additional means of presenting information using vibrotactile display devices. In this context, spatial displacement of a vibrotactile stimulus can be deployed for information display. We research the spatial resolution of vibrotactile perception of different body parts, increasing the spatial resolution of vibrotactile displays,
and applications."

 
Haptics, E-Touch and Sensory Multimedia

hapticxperience

Multiple disciplines such as biomechanics, psychophysics, robotics, neuroscience, and software engineering converge to support haptics. Generally, haptic research can be organized into three communities: the robotics community, the human computer interface community, and the virtual reality community. We look at haptics as a new media. We research general principles in haptics, fundamental concepts in human haptic perception, haptic and graphic rendering, Tele-haptics, applications, etc.

Project Summary Haptic-based Virtual Reality (VR) applications have many merits. What is still obscure, from the designer’s perspective of these applications, is the experience the users will undergo when they use the VR system. Quality of Experience (QoE) is an evaluation metric from the user’s perspective that we seek to measure in this project. Assessing the QoE of VR applications reflects the amount of overall satisfaction and benefits gained from the application in addition to laying the foundation for ideal user-centric design in the future. Our goal in this project is threefold, first is proposing a taxonomy for the evaluation of QoE for multimedia applications and in particular VR applications. Secondly, modeling this taxonomy using a Fuzzy logic Inference System (FIS) to quantitatively measure the QoE of haptic virtual environments. Finally, testing our FIS by conducting usability analysis to evaluate the QoE of diverse haptic applications.

 
Ambient Intelligence for Reducing Power Consuption

Reseracher : Eric Torunski

Using artificial intelligence, a computer could monitor electricity usage within a home and schedule certain household tasks for when electricity usage is low. These tasks could include running the dishwasher, cooling the fridge, heating the hot water tank, running the laundry or drying machine. If hybrid or electric cars become prevalent, the battery in the car could be used as a temporary energy source to power household devices when energy usage in the house is high, and then the car battery could recharge itself during the night when electricity usage is low. Also, if one is gone on vacation, the car could put its stored energy back into the utility grid for others to use when demand is high, and again recharge itself when demand is low.

 
Mulimedia Security (Watermarking) and Tele-Surveillance



The rapid growth of digital techniques makes it possible to create many new multimedia communication services such as teleconferencing, video on demand, direct broadcasting satellite, and HDTV, which creates an increasing need for video/image quality metrics. Our goal is to develop an objective quality measurement framework that works as an automatic quality monitoring system in a digital television network by using digital watermarking.

IT Security & Biometrics

Personal identity refers to a set of attributes (e.g., name, social insurance number, etc.) that are associated with a person. Identity management is the process of creating, maintaining and destroying identities of individuals in a population. Biometrics based authentication systems offer a reliable solution for identity management, because of their uniqueness, relative stability over time and security (among other reasons). Public acceptance of biometric systems will depend on their ability to ensure robustness, accuracy and security. And although robustness and accuracy of such systems are rapidly improving, there still remains the huge issue of security and balancing it with privacy. In this research we investigate the vulnerabilities of biometric systems especially template security of iris-based biometric authentication systems. Our goal is a template protection scheme with provable security and acceptable recognition performance that serves both securing the templates as well as preventing their unauthorized cross-referencing with other databases. "Any society that would give up a little liberty to gain a little security will deserve neither and lose both" (Ben Franklin)
