Using implicit user feedback to balance energy consumption and user comfort of proximity-controlled computer screens

This paper presents a dynamically adaptive proximity controller (APC) to balance energy consumption and user comfort of computer screens in office environments. Our APC system detects desk activities, such as working with the computer screen (screen on) and being away (screen off) and controls screens accordingly. Ultra-sound range (USR) sensors were used to measure user proximity. ...

Bio-inspired relevant interaction modelling in cognitive crowd management

Cognitive algorithms, integrated in intelligent systems, represent an important innovation in designing interactive smart environments. More in details, Cognitive Systems have important applications in anomaly detection and management in advanced video surveillance. These algorithms mainly address the problem of modelling interactions and behaviours among the main entities in a ...

A situation-aware safety service for children via participatory design

Children are mostly neglected as technology end users, even though they have needs and requirements that should be taken into account in the design of new products and services. This paper introduces a process for a designing situation-aware safety service for children with a unique combination of novel participatory tools, a brainstorming workshop, and scenario writing. The design ...

How to build a faster private information retrieval protocol?

A CPA secure multi-bit somewhat homomorphic encryption scheme based on Learning With Errors over Rings assumption is presented. We use canonical embedding to transform ring elements into vectors over Z q , and thus decrease encryption and decryption cost. Comparing with GHV scheme appeared in 2010, to encrypt n bits, this scheme can reduce encryption cost from O(n 3/2) into O(nlog ...

Comparative measures of aggregated uncertainty representations

Uncertainty must be taken into account in all aspects of ambient intelligence and human decisions and activities. We investigate how to utilize both probabilistic and possibilistic sources of information for use in humanized decision-making. In particular we examine aspects of the possibilistic conditioning of probability developed by Yager. To provide bounding of the resulting ...

Pedestrian identification by associating wearable and environmental sensors based on phase dependent correlation of human walking

Providing personal and location-dependent services is one of the promising services in public spaces like a shopping mall. So far, sensors in the environment have reliably detected the current positions of humans, but it is difficult to identify people using these sensors. On the other hand, wearable devices can send their personal identity information, but precise position ...

Providing relevant information in an ambient services using service requester’s “logical area”

Ambient service is a kind of context-aware services which is related to the surrounding environment of the users. In other words, geographic area around the users is considered as contextual data to provide services. This geographical area around the user is called logical area which would be equivalent for “here” from an ordinary user’s point of view. Most of the time users are ...

Electronic triage system for continuously monitoring casualties at disaster scenes

Unfortunately, many persons are injured or killed during disasters. The problems of paper triage tags, which are widely used at disaster scenes, include an inability to show the current priorities of casualties and a failure to collect the physiological conditions of the casualties. To save lives, this paper proposes an electronic triage system that consists of two types of ...

Cognitive hierarchical active partitions in distributed analysis of medical images

Semantic oriented image analysis has always been considered a challenging task, as it does not concentrate on segmentation process itself, but on interpretation of various image fragments. Contextuality of the process has recently gained significant research interest, with knowledge from image domain being repeatedly highlighted as crucial in achieving satisfactory method ...

The adARC pattern analysis architecture for adaptive human activity recognition systems

Most approaches to recognize human activities rely on pattern recognition techniques that are trained once at design time, and then remain unchanged during usage. This reflects the assumption that the mapping between sensor signal patterns and activity classes is known at design-time. This cannot be guaranteed in mobile and pervasive computing, where unpredictable changes can often ...

An ambient agent architecture exploiting automated cognitive analysis

In this paper an agent-based ambient agent architecture is presented based on monitoring human’s interaction with his or her environment and performing cognitive analysis of the causes of observed or predicted behaviour. Within this agent architecture, a cognitive model for the human is taken as a point of departure. From the cognitive model it is automatically derived how internal ...
