Awori, Kagonya, Gonçalves, Andreia, Clark, Emme, Effner, Troy, Yang, Justine, Oakley, Ian and Nunes, Nuno (2012): Supporting the aviation industry: a traveler-centered approach. In: Proceedings of DIS12 Designing Interactive Systems 2012. pp. 693-696.
“The aviation industry is fundamental to today's connected global economies, rapidly and effectively linking people, places and cultures. However, aviation struggles to provide a high quality of service; air travelers typically report dissatisfaction and frustration with their experiences. This paper describes fieldwork in the form of 63 interviews that aims to understand the needs of air travelers in order to improve user experiences during and around air travel. Three themes from this traveler-centered user research process are presented and the design of FlyTalk, a mobile phone application inspired by this data and tailored to the needs of air travelers is described. FlyTalk collates existing information about airports and their procedures, presents this to users in a location and context aware interface and seamlessly integrates social media features connecting travelers with both their service providers and each other. This paper argues air travel is an important but overlooked domain for HCI practitioners and that mobile applications that meet user needs in this scenario have the potential to reduce travel costs while improving traveler satisfaction.”

Oakley, Ian and Bianchi, Andrea (2012): Multi-touch passwords for mobile device access. In: Proceedings of the 2012 International Conference on Uniquitous Computing 2012. pp. 611-612.
“Draw-a-Secret password schemes, like the Google Android Pattern Lock, entail stroking out a shape on a touch screen. This paper explores techniques for expanding the richness of this input modality (multitouch input, off-target interaction) in order to increase password entropy and resistance to observation. A formative user study highlights user perceptions and usability issues relating to this design space and suggests directions for future development of this concept.”

Eslambolchilar, Parisa, Wilson, Max, Oakley, Ian and Dey, Anind (2011): PINC: persuasion, influence, nudge & coercion through mobile devices. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 13-16.
“This workshop will provide a focal point for research and technology dedicated to supporting behaviour change through Persuasion, Influence, Nudge and Coercion (PINC). A particular focus is on pervasive and mobile technologies and the unique opportunities they present in this domain (e.g. in terms of data-capture and timely intervention). Although much isolated research takes place tackling particular aspects of this problem space (e.g. persuasion), this workshop will be the first venue to provide a forum that discusses meta-issues that apply to behaviour change and pervasive technology, irrespective of how it is achieved. These issues include: (a) What novel opportunities do pervasive technologies provide? (b) When is the appropriate time to begin, reduce or end intervention? (c) Are PINC methods ethical? and (d) How can we extend the scale of intervention?Participants are invited to contribute to the workshop with examples of PINC technologies, and the event will focus on mapping the conceptual space, creating novel ideas and interactive applications and discussing future opportunities. Ultimately, the workshop aspires to establish a community dedicated to this topic.”

“Sensitive digital content associated with or owned by individuals now pervades everyday life. Mediating accessing to it in ways that are usable and secure is an ongoing challenge. This paper briefly discusses a series of five PIN entry and transmission systems that address observation attacks in public spaces via shoulder surfing or camera recording. They do this through the use of novel modalities including audio cues, haptic cues and modulated visible light. Each prototype is introduced and motivated, and its strengths and weaknesses are considered. The paper closes with a general discussion of the relevance of this work and the upcoming issues it faces.”

Esteves, Augusto and Oakley, Ian (2011): Informing design by recording tangible interaction. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2077-2082.
“Evaluating tangible user interfaces is challenging. Despite the wealth of research describing the design of tangible systems, there is little empirical evidence highlighting the benefits they can confer. This paper presents a toolkit that logs the manipulation of tangible objects as a step towards creating specific empirical methods for the study of tangible systems. The paper argues that the data derived from toolkit can be used in three ways. Firstly: to compare tangible interaction with other interaction paradigms. Secondly: to compare among different tangible interfaces performing the same tasks. Thirdly: via integration into a structured design process. This paper focuses on this last topic and discusses how detailed data regarding object use the data could be integrated into classifications and frameworks such as the Shaer's et al's TAC paradigm.”

Bianchi, Andrea, Oakley, Ian and Kwon, Dong Soo (2011): Using mobile device screens for authentication. In: Proceedings of the 2011 Australian Computer-Human Interaction Conference 2011. pp. 50-53.
“Authentication in public spaces, such as ATM PIN entry, is inherently susceptible to security attacks based on observation in person or via cameras. This paper addresses this problem with a system which allows users to enter a PIN on a standard mobile phone and then transmit it securely for authentication using modulated patterns of light shown on the screen and sensed by a cheap bespoke receiver unit. No pre-pairing is required as physical proximity guarantees security. The paper presents several hardware and software variations, evaluates the technical soundness of the system, and presents two user studies addressing usability and security against observation attacks.”

Esteves, Augusto and Oakley, Ian (2010): Mementos: a tangible interface supporting travel. In: Proceedings of the Sixth Nordic Conference on Human-Computer Interaction 2010. pp. 643-646.
“Tangible interaction promises interfaces with ready affordances, which embrace physicality and which naturally support collaboration. However, the complexity of the hardware required to produce tangible systems has typically constrained their operation to highly specialized application areas and particular physical environments. This paper argues that this has limited the scope of research into such systems and addresses this issue by presenting Mementos, a tangible interface for tourists and travelers and intended to support all stages of a trip: preparation, experience, and remembering and reflecting. In this way, it explores how tangible interaction can support a complex real world task spread across time and multiple contexts. The paper describes the design, implementation and early evaluation of Mementos. It concludes that such work takes an important step towards popularizing tangible interaction.”

In: Proceedings of 12th Conference on Human-computer interaction with mobile devices and services 2010. pp. 55-58.
“This paper presents a multi-pronged study of users' location-sharing practices in the context of online social networks. The contribution of this study is two-fold: first it presents a series of insights relating to location-sharing practices, and second it highlights the use of third-person scenarios as a useful method for eliciting privacy concerns and potentially educating users.”

“Authentication in public spaces poses significant security risks. Most significantly, passwords can be stolen, potentially leading to fraud. A common method to steal a PIN is through an observation attack, either using a camera or through direct observation (e.g. shoulder-surfing). This paper addresses this problem by presenting the design and implementation of a novel input keypad which uses tactile cues as means to compose a password. In this system, passwords are encoded as a sequence of randomized vibration patterns, making it visually impossible for an observer to detect which items are selected. An evaluation of this system shows it outperforms previous interfaces which have used tactile feedback to obfuscate passwords.”

“Authentication through passwords in public spaces (such as in ATMs) is susceptible to simple observation attacks, such as shoulder surfing, which can result in the password being compromised and ultimately the exposure of users to fraud and theft. Haptic technology, which can present information non-visually to users, offers a potential solution to this problem through the creation of tactile passwords. Situated in this space, this paper presents the design and initial evaluation of a novel haptic device, the haptic wheel, which displays tactons, or structured tactile messages, to enable password entry. It describes this device and the tactile passwords it supports in detail before presenting two short user studies. The results of these reveal that the chosen tactons are easily identifiable and that password entry times are significantly improved compared to previous systems based on haptic authentication.”

Kostakos, Vassilis and Oakley, Ian (2009): Designing trustworthy situated services: an implicit and explicit assessment of locative images-effect on trust. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 329-332.
“This paper examines a visual design element unique to situated, hot-spot style, services: locativeness. This is the extent to which the media representing a service relates to its immediate physical environment. This paper explores the effect of locativeness on trust with two studies assessing user attitudes in depth. The first is an implicit, or preconscious, test and the second an explicit test based on voiced value judgments. To provide a richer context, the second study contrasts locativeness with other traditional aspects of design: branding and quality. The results indicate users have a strong implicit association between locative images and trust, and that this is partially reflected in their explicit choices. This is an important interface aspect that designers should consider in order to create trustworthy situated services.”

Oakley, Ian and Park, Junseok (2009): Motion marking menus: An eyes-free approach to motion input for handheld devices. In International Journal of Human-Computer Studies, 67 (6) pp. 515-532.
“The increasing complexity of applications on handheld devices requires the development of rich new interaction methods specifically designed for resource-limited mobile use contexts. One appealingly convenient approach to this problem is to use device motions as input, a paradigm in which the currently dominant interaction metaphors are gesture recognition and visually mediated scrolling. However, neither is ideal. The former suffers from fundamental problems in the learning and communication of gestural patterns, while the latter requires continual visual monitoring of the mobile device, a task that is undesirable in many mobile contexts and also inherently in conflict with the act of moving a device to control it. This paper proposes an alternate approach: a gestural menu technique inspired by marking menus and designed specifically for the characteristics of motion input. It uses rotations between targets occupying large portions of angular space and emphasizes kinesthetic, eyes-free interaction. Three evaluations are presented, two featuring an abstract user interface (UI) and focusing on how user performance changes when the basic system parameters of number, size and depth of targets are manipulated. These studies show that a version of the menu system containing 19 commands yields optimal performance, compares well against data from the previous literature and can be used effectively eyes free (without graphical feedback). The final study uses a full graphical UI and untrained users to demonstrate that the system can be rapidly learnt. Together, these three studies rigorously validate the system design and suggest promising new directions for handheld motion-based UIs.”

Oakley, Ian, Sunwoo, John and Cho, Il-Yeon (2008): Pointing with fingers, hands and arms for wearable computing. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3255-3260.
“Pointing is a fundamental enabling operation for human-computer interaction across a broad spectrum of scenarios. The paper presents a study exploring how to develop a pointing system for truly wearable, rather than hand-held, computing. It describes a Fitts' law study of pointing based on motions in free-space captured using an inertial sensor pack. It compares performance when the pack is held in the hand, mounted on the back of the hand and finally on the wrist. The results show a significant, but numerically small, advantage in using the hands over using the upper arm only. This suggests that for wearable tasks where pointing is relatively infrequent a wrist based sensor pack may well be sufficient to enable effective and usable interaction.”

“Research on vibrotactile displays for mobile devices has developed and evaluated complex multi-dimensional tactile stimuli with promising results. However, the possibility that user distraction, an inevitable component of mobile interaction, may mask (or obscure) vibrotactile perception has not been thoroughly considered. This omission is addressed here with three studies comparing recognition performance on nine tactile icons between control and distracter conditions. The icons were two dimensional (three body sites against three roughness values) and displayed to the wrist. The distracter tasks were everyday activities: Transcription, mouse-based Data-entry and Walking. The results indicated performance significantly dropped in the distracter condition”

“Haptic devices are now commercially available and thus touch has become a potentially realistic solution to a variety of interaction design challenges. We report on an investigation of the use of touch as a way of reducing visual overload in the conventional desktop. In a two-phase study, we investigated the use of the PHANTOM haptic device as a means of interacting with a conventional graphical user interface. The first experiment compared the effects of four different haptic augmentations on usability in a simple targeting task. The second experiment involved a more ecologically-oriented searching and scrolling task. Results indicated that the haptic effects did not improve users performance in terms of task completion time. However, the number of errors made was significantly reduced. Subjective workload measures showed that participants perceived many aspects of workload as significantly less with haptics. The results are described and the implications for the use of haptics in user interface design are discussed.”
