In this paper, we describe HomeNetViewer, a system for collecting, visualising and annotating domestic network NetFlow records from a domestic network gateway. HomeNetViewer is designed to collect ground truth data which, enables the linking of users to low level network traffic. We present our first annotated dataset from a real household in the UK and the results of our preliminary work to build a user identification system. Our initial classifier achieves a true-positive rate of 64% with false-positive rate of 28% when compared to the ground truth annotations. This work attempts to address the lack of transparency and accountability within the domestic network infrastructure by identifying the user behind the device.

The Moment is a mobile application for people with depression or bipolar disorder to monitor their emotional ups and downs, reveal their emotional patterns, and eventually find a peaceful way to live with their emotions, rather than fighting with them. The system consists of two main components: a smartphone application for the users to track their feelings and memories about events, and a sensor recording their physiological responses. The data will then be visualized in several ways and can be shared with trusted individuals or mental health professionals. The goal is to make the user more aware of her mood swings and the precursors to them; to reveal patterns of the swings; to provide a record for healthcare providers; to build a library of personalized interventions for future use; and to create an effective network of social supports.
The Moment是一款针对抑郁症或双相情感障碍患者的移动应用程序，用于监测他们的情绪起伏，揭示他们的情绪模式，最终找到一种和平的方式与他们的情绪生活在一起，而不是与他们斗争。该系统由两个主要部分组成:一个用于用户追踪他们对事件的感受和记忆的智能手机应用程序，以及一个记录他们生理反应的传感器。然后，这些数据将以多种方式可视化，并可以与值得信赖的个人或心理健康专业人员共享。这样做的目的是让用户更加意识到自己的情绪波动及其前兆;揭示摆动的模式;为医疗保健提供者提供记录;建立个性化干预措施库，以备将来使用;并建立一个有效的社会支持网络。

People respond emotionally to other people, animals, or even objects like furniture. While current furniture is static in appearance, embedded electronics can enable furniture to change its appearance. A couch could show excitement during a party or anger when a pet scratches it. But would emotional furniture delight or annoy people? To explore the potential for emotional furniture, we built EmotoCouch. Through colored light, visual patterns, and haptic feedback, EmotoCouch expresses six emotional states: Excited, Happy, Calm, Depressed/Sad, Afraid, and Angry. This video describes the construction of EmotoCouch, feedback gathered through surveys and user interviews, and shows example EmotoCouch usage situations.

Authenticating users of computer systems based on their brainwave signals is now a realistic possibility, made possible by the increasing availability of EEG (electroencephalography) sensors in wireless headsets and wearable devices. This possibility is especially interesting because brainwave-based authentication naturally meets the criteria for two-factor authentication. To pass an authentication test using brainwave signals, a user must have both an inherence factor (his or her brain) and a knowledge factor (a chosen passthought). In this study, we investigate the extent to which both factors are truly necessary. In particular, we address the question of whether an attacker may gain advantage from information about a given target's secret thoughts.

In this work, we present ChildSafe, a classification system which exploits human skeletal features collected using a 3D depth camera to classify visual characteristics between children and adults. ChildSafe analyzes the histograms of training samples and implements a bin-boundary-based classifier. We train and evaluate ChildSafe using a large dataset of visual samples collected from 150 elementary school children and 43 adults, ranging in the ages of 7 and 50. Our results suggest that ChildSafe successfully detects children with a proper classification rate of up to 97%, a false negative rate of as low as 1.82%, and a low false positive rate of 1.46%. We envision this work as an effective sub-system for designing various child protection applications.

We present BendID, a bendable input device that recognizes the location, magnitude and direction of its deformation. We use BendID to provide users with a tactile metaphor for pressure based input. The device is constructed by layering an array of indium tin oxide (ITO)-coated PET film electrodes on a Polymethylsiloxane (PDMS) sheet, which is sandwiched between conductive foams. The pressure values that are interpreted from the ITO electrodes are classified using a Support Vector Machine (SVM) algorithm via the Weka library to identify the direction and location of bending. A polynomial regression model is also employed to estimate the overall magnitude of the pressure from the device. A model then maps these variables to a GUI to perform tasks. In this preliminary paper, we demonstrate this device by implementing it as an interface for 3D shape bending and a game controller.

The human sensory network provides an immediate interface by which to gauge ambient properties of the environment, registering pressure, sound, odor, etc. However, sensory loss can drastically diminish one's ability to process such ambient information, exposing an individual to potentially harmful situations. Smart Garments, capable of computation, communication, sensing, and actuation, have the ability to offset potentially hazardous circumstances associated with sensory loss by augmenting the human sensory capabilities. This research explores how Smart Garments can support those with a hearing impairment by leveraging the proximity and surface area of the human skin to provide contextual information (vibrotactile cues approximating the direction of critical environmental sounds) to a user.

Ubicomp technologies pose challenges to human agency, and legal rights reliant on individual autonomy, for example informed consent to data processing. Existing regulatory measures designed to address these issues are working less adequately, and increased dialogue between design and law communities is necessary to decide how best to ensure effective regulation of human autonomy. This thesis seeks to understand the various regulatory issues posed by ubicomp technologies, through specific case studies, with the overall aim of creating legal and technological solutions that work in practice.

Among the data that can now be readily sensed and shared, we believe temperature has potential to support relationships, because people perceive warmth as intimate and temperature as indicative of comfort and wellness. We interviewed 20 participants who interacted with prototypes of temperature sensing and sharing systems. Participants believed that shared temperature information could make their remote relationships stronger by supporting coordination, reassurance, and intimacy. They also perceived many challenges common in UbiComp -- such as difficulty interpreting data and tradeoffs between intimacy and privacy. We discuss nuances and guidelines for using temperature information as "shared informatics" and how these results can inform future research and system designs.

Ambient Assisted Living (AAL) technologies offer a promising perspective on autonomous aging in place. This is in the interest of the older adults themselves, overburdened caregivers and policy makers who try to control health care budgets in the face of the ever growing older population. However, these technologies are still in their infancy and little is known whether the older adults are ready to adopt and use them. So far, most research efforts are of exploratory nature. While they identify factors which are important for the adoption and use of AAL technologies, only a few attempt to test and quantify the underlying relations between these factors. Furthermore, many studies focus on a pre-adoption stage (a technology has not been used yet) and do not consider post-adoption (users have used and experienced a technology). This dissertation seeks to fill this gap by constructing a model which tests the underlying relations between the various influencing factors across both pre-adoption and post-adoption stages.
