User Perceptions of Smart Home IoT Privacy
Smart home Internet of Things (IoT) devices are rapidly increasing in
popularity, with more households including Internet-connected devices that
continuously monitor user activities. In this study, we conduct eleven
semi-structured interviews with smart home owners, investigating their reasons
for purchasing IoT devices, perceptions of smart home privacy risks, and
actions taken to protect their privacy from those external to the home who
create, manage, track, or regulate IoT devices and/or their data. We note
several recurring themes. First, users' desires for convenience and
connectedness dictate their privacy-related behaviors for dealing with external
entities, such as device manufacturers, Internet Service Providers,
governments, and advertisers. Second, user opinions about external entities
collecting smart home data depend on perceived benefit from these entities.
Third, users trust IoT device manufacturers to protect their privacy but do not
verify that these protections are in place. Fourth, users are unaware of
privacy risks from inference algorithms operating on data from non-audio/visual
devices. These findings motivate several recommendations for device designers,
researchers, and industry standards to better match device privacy features to
the expectations and preferences of smart home owners.Comment: 20 pages, 1 tabl
Proceedings of the 4th Workshop on Interacting with Smart Objects 2015
These are the Proceedings of the 4th IUI Workshop on Interacting with
Smart Objects. Objects that we use in our everyday life are expanding
their restricted interaction capabilities and provide functionalities
that go far beyond their original functionality. They feature computing
capabilities and are thus able to capture information, process and store
it and interact with their environments, turning them into smart objects

Meanwhile, visible light communication (VLC) using light devices such as light emitting diodes (LEDs) has been deemed to be a promising candidate in the heterogeneous wireless networks that may collaborate with radio frequencies (RF) wireless networks. In particular, light-fidelity has a great potential for deployment in future indoor environments because of its high throughput and security advantages. This paper provides a comprehensive study of a novel positioning technology based on visible white LED lights, which has attracted much attention from both academia and industry. The essential characteristics and principles of this system are deeply discussed, and relevant positioning algorithms and designs are classified and elaborated. This paper undertakes a thorough investigation into current LED-based indoor positioning systems and compares their performance through many aspects, such as test environment, accuracy, and cost. It presents indoor hybrid positioning systems among VLC and other systems (e.g., inertial sensors and RF systems). We also review and classify outdoor VLC positioning applications for the first time. Finally, this paper surveys major advances as well as open issues, challenges, and future research directions in VLC positioning systems.Peer reviewe
Body-Area Capacitive or Electric Field Sensing for Human Activity Recognition and Human-Computer Interaction: A Comprehensive Survey
Due to the fact that roughly sixty percent of the human body is essentially
composed of water, the human body is inherently a conductive object, being able
to, firstly, form an inherent electric field from the body to the surroundings
and secondly, deform the distribution of an existing electric field near the
body. Body-area capacitive sensing, also called body-area electric field
sensing, is becoming a promising alternative for wearable devices to accomplish
certain tasks in human activity recognition and human-computer interaction.
Over the last decade, researchers have explored plentiful novel sensing systems
backed by the body-area electric field. On the other hand, despite the
pervasive exploration of the body-area electric field, a comprehensive survey
does not exist for an enlightening guideline. Moreover, the various hardware
implementations, applied algorithms, and targeted applications result in a
challenging task to achieve a systematic overview of the subject. This paper
aims to fill in the gap by comprehensively summarizing the existing works on
body-area capacitive sensing so that researchers can have a better view of the
current exploration status. To this end, we first sorted the explorations into
three domains according to the involved body forms: body-part electric field,
whole-body electric field, and body-to-body electric field, and enumerated the
state-of-art works in the domains with a detailed survey of the backed sensing
tricks and targeted applications. We then summarized the three types of sensing
frontends in circuit design, which is the most critical part in body-area
capacitive sensing, and analyzed the data processing pipeline categorized into
three kinds of approaches. Finally, we described the challenges and outlooks of
body-area electric sensing
Ubiquitous Computing for Remote Cardiac Patient Monitoring: A Survey
New wireless technologies, such as wireless LAN and sensor networks, for telecardiology purposes give new possibilities for monitoring vital parameters with wearable biomedical sensors, and give patients the freedom to be mobile and still be under continuous monitoring and thereby better quality of patient care. This paper will detail the architecture and quality-of-service (QoS) characteristics in integrated wireless telecardiology platforms. It will also discuss the current promising hardware/software platforms for wireless cardiac monitoring. The design methodology and challenges are provided for realistic implementation
