The widespread usage of mobile devices together with their computational capabilities enables the implementation of novel interaction techniques to improve user performance in traditional mobile applications. Navigation assistance is an important area in the mobile domain, and probably Google Maps is the most popular example. This type of applications is highly demanding for user’s attention, e...

Mobile applications and specifically wellness applications are used increasingly by different age-segments of the general population. This is facilitated by the large amount of data collected through various built-in sensors in the smartphone or other mobile devises, e.g. smart watches. Young-elderly cohort (60-75 year old individual) is probably one of the most potential user groups that would...

Neurons in the monkey motor cortex that project to the spinal cord to control particular muscle contractions and movements have been found to discharge again while the monkey simply watches another primate make similar movements: monkey see; monkey not do.

Video surveillance systems must support multiple streaming and prompt alert notification. We propose a two-tiered environment: a supervisor defines presentation layouts and model interface reactions to alerts; a surveillant watches synchronized videos, adapts layouts, and is notified with alerts.

The integration of gas sensor components into smart phones, tablets and wrist watches will revolutionize the environmental health and safety industry by providing individuals the ability to detect harmful chemicals and pollutants in the environment using always-on hand-held or wearable devices. Metal oxide gas sensors rely on changes in their electrical conductance due to the interaction of the...

In many scenarios, such as emergency response or ad hoc collaboration, it is critical to reduce the overhead in integrating data. Here, the goal is often to rapidly integrate “enough” data to answer a specific question. Ideally, one could perform the entire process interactively under one unified interface: defining extractors and wrappers for sources, creating a mediated schema, and adding sch...

By incorporating a growing number of sensors and adopting machine learning technologies, wearable devices have recently become a prominent health care application domain. Among the related research topics in this field, one of the most important issues is detecting falls while walking. Since such falls may lead to serious injuries, automatically and promptly detecting them during daily use of s...

Most group key agreement protocols make use of modular exponential operations which require extensive computing resources in devices. Thus, they are unsuitable for resourceconstrained devices such as mobile phones, smart cards and intelligent watches. This paper proposes a group key agreement protocol based on braid groups which requires only multiplication operations. The proposed protocol is ...

Hospital readmission rate is high for heart failure patients. Early detection of deterioration will help doctors prevent readmissions, thus reducing health care cost and providing patients with just-in-time intervention. Wearable devices (e.g., wristbands and smart watches) provide a convenient technology for continuous outpatient monitoring. In the paper, we explore the feasibility of monitori...
