- PublicationI Really did That: Sense of Agency with Touchpad, Keyboard, and On-skin InteractionInput on the skin is emerging as an interaction style. At CHI 2012, Coyle and colleagues identified an increase in the sense of agency (SoA) as one benefit of skin input. However, their study only compared skin input to button presses and has not, to our knowledge, been replicated. Therefore, we had 24 participants compare skin input to both button presses and touch-pad input, measuring SoA using the Libet Clock paradigm. We replicate previous findings regarding increased SoA in skin versus button input and also find that SoA for skin is significantly increased compared to touch-pad input. Interview data addressing subjective experience further support these findings. We discuss agency and the experiences associated with skin input, as well as differences to input with non-skin devices.

; ; ; ; ; ; ; Intelligent Personal Assistants (IPAs) are widely available on devices such as smartphones. However, most people do not use them regularly. Previous research has studied the experiences of frequent IPA users. Using qualitative methods we explore the experience of infrequent users: people who have tried IPAs, but choose not to use them regularly. Unsurprisingly infrequent users share some of the experiences of frequent users, e.g. frustration at limitations on fully hands-free interaction. Significant points of contrast and previously unidentified concerns also emerge. Cultural norms and social embarrassment take on added significance for infrequent users. Humanness of IPAs sparked comparisons with human assistants, juxtaposing their limitations. Most importantly, significant concerns emerged around privacy, monetization, data permanency and transparency. Drawing on these findings we discuss key challenges, including: designing for interruptability; reconsideration of the human metaphor; issues of trust and data ownership. Addressing these challenges may lead to more widespread IPA use.1764Scopus© Citations 249 - PublicationUser Experience of Cognitive Behavioral Therapy Apps for Depression: An Analysis of App Functionality and User Reviews(JMIR, 2018-06-06)
; ; ; ; Background: Hundreds of mental health apps are available to the general public. With increasing pressures on healthcare systems. they offer a potential way for people to support their mental health and well-being. However, while many are highly rated by users, few are evidence-based. Equally, our understanding of what makes apps engaging and valuable to users is limited. Objective: The aim of this paper was to analyse functionality and user opinions of mobile applications (apps) purporting to support Cognitive Behavioural Therapy (CBT) for depression and to explore key factors that have impact on user experience and support engagement. Methods: We systematically identified apps described as being based on CBT for depression. We then conducted two studies. In the first, we analysed the therapeutic functionality of apps. This corroborated existing work on apps’ fidelity to CBT theory, but we also extended prior work by examining features designed to support user engagement. Engagement features found in CBT apps for depression were compared with those found in a larger group of apps that support mental well-being in a more general sense. Our second study involved a more detailed examination of user experience, through a thematic analysis of publicly available user reviews of CBT apps for depression. Results: We identified 31 apps that purport to be based on CBT for depression. Functionality analysis (Study 1) showed that they offered an eclectic mix of features, including many not based on CBT practice. CBT apps used less varied engagement features compared to 253 other mental well-being apps. The analysis of 1,287 user reviews of CBT apps for depression (Study 2) showed that apps are used in a wide range of contexts, both replacing and augmenting therapy, and allowing users to take active role in supporting their mental health and well-being. Users, including health professionals, valued and used apps that incorporated both core CBT and non-CBT elements, but concerns were also expressed regarding the unsupervised use of apps. Positivity was seen as important to engagement, e.g. in the context of automatic thoughts, users express a preference to capture not just negative, but also positive ones. Privacy, security and trust were crucial to the user experience. Conclusions: CBT apps for depression need to do a better job of incorporating evidence-based CBT elements. Equally, a positive user experience is dependent on other design factors, including consideration of varying contexts of use. App designers should be able to clearly identify the therapeutic basis of their apps, but they should also draw on evidence-based strategies to support a positive and engaging user experience. The most effective apps are likely to strike a balance between evidence-based CBT strategies and evidence-based design strategies, including the possibility of eclectic therapeutic techniques.627Scopus© Citations 117 - PublicationUsing Emotional Attachment as a Lens to Improve Users E-reading Experience(International Journal of Interaction Design and Architecture, 2017)
; ; ; This paper explores ways to improve e-reading by examining theexperience of people who have developed a sense of attachment to their ereaders.Nine participants who reported experiencing emotional attachmentcompleted a semi-structured interview asking them about their experiences withe-readers and e-reading. Thematic analysis led to three main themes beingidentified as important to their experiences: projection of identity, control overthe device, and environmental factors. We examine how these themes suggestthat peoples experiences of reading in traditional and electronic formats areheavily interlinked. We also discuss how these themes resonate with the widerattachment literature. Based on our findings we suggest the need to support theexpression of identity through configuration and display in the e-readerexperience, as well as exploring ways devices can be used to control andpersonalize the reading environment.327
