To form a deep understanding of the present; we need to construct and engage an account of the past. In this paper, we present an informal history capture and retrieval mechanism for collaborative, early-stage information design. This history system is implemented in the context of the Designers'' Outpost, a wall-scale, tangible interface for collaborative web site design. The interface elements in this history system are designed to be fluid and comfortable for early phase design. As demonstrated by an informal lab study with six professional web site designers, this history system enhances the design process itself, and provides new opportunities for reasoning about the design of complex artifacts.

In the world's largest-ever deployment of online voting, the iVote Internet voting system was trusted for the return of 280,000 ballots in the 2015 state election in New South Wales, Australia. During the election, we performed an independent security analysis of parts of the live iVote system and uncovered severe vulnerabilities that could be leveraged to manipulate votes, violate ballot privacy, and subvert the verification mechanism. These vulnerabilities do not seem to have been detected by the election authorities before we disclosed them, despite a pre-election security review and despite the system having run in a live state election for five days. One vulnerability, the result of including analytics software from an insecure external server, exposed some votes to complete compromise of privacy and integrity. At least one parliamentary seat was decided by a margin much smaller than the number of votes taken while the system was vulnerable. We also found protocol flaws, including vote verification that was itself susceptible to manipulation. This incident underscores the difficulty of conducting secure elections online and carries lessons for voters, election officials, and the e-voting research community.

The New South Wales iVote System: Security Failures and Verification Flaws in a Live Online Election

Smart home technology provides a suite of independently and remotely controlled software and hardware that are connected into a network to deliver smart living. Smart homes have immense potential to shape the future living, and the market is maturing, but factors influencing households’ adoption of smart home technology services are still an understudied area. The study aims to identify the prominent smart home technology services and generate an understanding of the motivations, barriers, and risks of adoption from a consumer perspective. The paper reviews the literature and builds a conceptual framework of smart home adoption. The findings disclose: (a) Prominent technology services are associated with healthcare, energy efficiency and home security; (b) Primary motivations to adopt smart home technology services include efficient energy management, better home-based healthcare services, potential financial savings and benefits, and enhanced quality of life; (c) Main barriers to the smart home adoption include the distrust and resistance, limited perception of smart home, concerns of financial issues, privacy and security concerns, technology anxiety and negative social influences, and; (d) Main risks include privacy and security threats, energy rebounds and wasteful consumption, difficulty in the domestication of technology and destructiveness in domestic life.

Motivations, barriers and risks of smart home adoption: From systematic literature review to conceptual framework

With the proliferation of room-scale Virtual Reality (VR), more and more users install a VR system in their homes. When users are in VR, they are usually completely immersed in their application. However, sometimes passersby invade these tracking spaces and walk up to users that are currently immersed in VR to try and interact with them. As this either scares the user in VR or breaks the user's immersion, research has yet to find a way to seamlessly represent physical passersby in virtual worlds. In this paper, we propose and evaluate three different ways to represent physical passersby in a Virtual Environment using Augmented Virtuality. The representations encompass showing a Pointcloud, showing a 3D-Model, and showing an Image Overlay of the passerby. Our results show that while an Image Overlay and a 3D-Model are the fastest representations to spot passersby, the 3D-Model and the Pointcloud representations were the most accurate.

IoT devices no longer affect single users only because others like visitors or family members - denoted as bystanders - might be in the device’s vicinity. Thus, data about bystanders can be collected by IoT devices and bystanders can observe what IoT devices output. To better understand how this affects the privacy of IoT device owners and bystanders and how their privacy can be protected better, we interviewed 42 young adults. Our results include that owners of IoT devices wish to adjust the device output when visitors are present. Visitors wish to be made aware of the data collected about them, to express their privacy needs, and to take measures. Based on our results, we show demand for scalable solutions that address the tension that arises between the increasing discreetness of IoT devices, their increase in numbers and the requirement to preserve the self-determination of owners and bystanders at the same time.

Accurate sketching in virtual 3D environments is challenging due to aspects like limited depth perception or the absence of physical support. To address this issue, we propose VRSketchPen – a pen that uses two haptic modalities to support virtual sketching without constraining user actions: (1) pneumatic force feedback to simulate the contact pressure of the pen against virtual surfaces and (2) vibrotactile feedback to mimic textures while moving the pen over virtual surfaces. To evaluate VRSketchPen, we conducted a lab experiment with 20 participants to compare (1) pneumatic, (2) vibrotactile and (3) a combination of both with (4) snapping and no assistance for flat and curved surfaces in a 3D virtual environment. Our findings show that usage of pneumatic, vibrotactile and their combination significantly improves 2D shape accuracy and leads to diminished depth errors for flat and curved surfaces. Qualitative results indicate that users find the addition of unconstraining haptic feedback to significantly improve convenience, confidence and user experience.

With head-mounted displays (HMDs), users can access and interact with a broad range of applications and data. Although some of this information is privacy-sensitive or even confidential, no intuitive, unobtrusive and secure authentication technique is available yet for HMDs. We present LookUnlock, an authentication technique for HMDs that uses passwords that are composed of spatial and virtual targets. Through a proof-of-concept implementation and security evaluation, we demonstrate that this technique can be efficiently used by people and is resistant to shoulder-surfing attacks.

LookUnlock: Using Spatial-Targets for User-Authentication on HMDs

Abstract Smart Home technologies have the potential to increase the quality of life, home security and facilitate elderly care. Therefore, they require access to a plethora of data about the users’ homes and private lives. Resulting security and privacy concerns form a relevant barrier to adopting this promising technology. Aiming to support end users’ informed decision-making through addressing the concerns we first conducted semi-structured interviews with 42 potential and little-experienced Smart Home users. Their diverse concerns were clustered into four themes that center around attacks on Smart Home data and devices, the perceived loss of control, the trade-off between functionality and security, and user-centric concerns as compared to concerns on a societal level. Second, we discuss measures to address the four themes from an interdisciplinary perspective. The paper concludes with recommendations for addressing user concerns and for supporting developers in designing user-centered Smart Home technologies.
