Sensor Sleeve: Sensing Affective Gestures
We describe the use of textile sensors mounted in a garment sleeve to detect affective gestures. The `Sensor Sleeve' is part of a larger project to explore the role of affect in communications. Pressure activated, capacitive and elasto-resistive sensors are investigated and their relative merits reported on. An implemented application is outlined in which a cellphone receives messages derived from the sleeve's sensors using a Bluetooth interface, and relays the signals as text messages to the user's nominated partner
Virtual reality: Theoretical basis, practical applications
Virtual reality (VR) is a powerful multimedia visualization technique offering a range of mechanisms by which many new experiences can be made available. This paper deals with the basic nature of VR, the technologies needed to create it, and its potential, especially for helping disabled people. It also offers an overview of some examples of existing VR systems
Shake well before use: Authentication based on Accelerometer Data
Small, mobile devices without user interfaces, such as Bluetooth headsets, often need to communicate securely over wireless networks. Active attacks can only be prevented by authenticating wireless communication, which is problematic when devices do not have any a priori information about each other. We introduce a new method for device-to-device authentication by shaking devices together. This paper describes two protocols for combining cryptographic authentication techniques with known methods of accelerometer data analysis to the effect of generating authenticated, secret keys. The protocols differ in their design, one being more conservative from a security point of view, while the other allows more dynamic interactions. Three experiments are used to optimize and validate our proposed authentication method
Event-based sensor fusion in human-machine teaming
Realizing intelligent production systems where machines and human workers can team up seamlessly demands a yet unreached level of situational awareness. The machines' leverage to reach such awareness is to amalgamate a wide variety of sensor modalities through multisensor data fusion. A particularly promising direction to establishing human-like collaborations can be seen in the use of neuro-inspired sensing and computing technologies due to their resemblance with human cognitive processing. This note discusses the concept of integrating neuromorphic sensing modalities into classical sensor fusion frameworks by exploiting event-based fusion and filtering methods that combine time-periodic process models with event-triggered sensor data. Event-based sensor fusion hence adopts the operating principles of event-based sensors and even exhibits the ability to extract information from absent data. Thereby, it can be an enabler to harness the full information potential of the intrinsic spiking nature of event-driven sensors
Implicit Sensor-based Authentication of Smartphone Users with Smartwatch
Smartphones are now frequently used by end-users as the portals to
cloud-based services, and smartphones are easily stolen or co-opted by an
attacker. Beyond the initial log-in mechanism, it is highly desirable to
re-authenticate end-users who are continuing to access security-critical
services and data, whether in the cloud or in the smartphone. But attackers who
have gained access to a logged-in smartphone have no incentive to
re-authenticate, so this must be done in an automatic, non-bypassable way.
Hence, this paper proposes a novel authentication system, iAuth, for implicit,
continuous authentication of the end-user based on his or her behavioral
characteristics, by leveraging the sensors already ubiquitously built into
smartphones. We design a system that gives accurate authentication using
machine learning and sensor data from multiple mobile devices. Our system can
achieve 92.1% authentication accuracy with negligible system overhead and less
than 2% battery consumption.Comment: Published in Hardware and Architectural Support for Security and

Informational Model of Consciousness: From Philosophic Concepts to an Information Science of Consciousness
On the long and well-worn road of many, but justifiable attempts of human to discover his origin, his trajectory as a
species, and a suitable understanding consciousness, his system allowing the connection to the environment and to
his own organism, the concepts and models of philosophy enunciated or experienced by millennia, meet today with
modern science concepts of physics and of science of information. Based on recent discoveries of quantum physics
and astrophysics, revealing a new understanding of our environment and starting from some philosophical concepts
on information of matter and of living structures, this work discusses the dynamics of information within the frame
of the Informational Model of Consciousness as an informational system of the human body, connected both to the
environment and to the body itself, to control the adaptation for survival. It is shown that consciousness is actually
an informational projection in the mind of seven informational subsystems, three of which forming the operative
system of consciousness for the short-term adaptation, and other three forming the programmed operating system,
dedicated to the maintenance of body and to the long-term survival of species, showing various inputs and outputs
of information. The seventh subsystem is the information pole, connecting the organism with the external
information, especially related to the extra-sensorial properties of the mind, the human body appearing as a bipolar
info-matter structure, managed by the brain. The received information is progressively integrated into the
informational system of the organism, which absorbs and emanates information as a reactive system for adaptation,
able to operate both with matter-related (codified) and non-matter related (virtual) information. As both connections
with external and internal environment (body itself) can be described in terms of information, this model opens the
gate to investigate consciousness by means of the tools of the information science, offering also answers to the
philosophic âmind-bodyâ problem and to the âhardâ problem and showing correspondences with some ancient
philosophies
Context-aware QoS provisioning for an M-health service platform
Inevitably, healthcare goes mobile. Recently developed mobile healthcare (i.e., m-health) services allow healthcare professionals to monitor mobile patient's vital signs and provide feedback to this patient anywhere at any time. Due to the nature of current supporting mobile service platforms, m-health services are delivered with a best-effort, i.e., there are no guarantees on the delivered Quality of Service (QoS). In this paper, we argue that the use of context information in an m-health service platform improves the delivered QoS. We give a first attempt to merge context information with a QoS-aware mobile service platform in the m-health services domain. We illustrate this with an epilepsy tele-monitoring scenario
