Purpose To define the user needs and preferences of the athletic population in cardiac (tele)rehabilitation (CTR). Patients and Methods In this qualitative study, we included athletes with established coronary artery disease (CAD) who participated in a cardiac rehabilitation (CR) program and health care professionals involved in CR. All athletes engaged in sports for at least four hours per week. Fourteen male and one female athlete (mean age 63 ± 10.6 years) participated in CR after an acute coronary syndrome, percutaneous coronary intervention and/or coronary bypass surgery. The twelve healthcare professionals invited included cardiac nurse practitioners, cardiologists, sports physicians, physiotherapists, and a clinical psychologist. This study consists of four phases: a stakeholder identification session, twenty-five semi-structured individual interviews, six card-sorting focus groups and a data analysis phase with thematic analysis. Results User needs for athletes in CR encompass personalized exercise plans featuring clear and quantifiable exercise recommendations and limitations. Additionally, there is a need for monitoring health and exercise data; measuring progression and performance longitudinally; easy-to-use, and reliable healthcare information systems with accurate sensors and data; as well as clinical supervision and validation of information and data. Social support from both peers and family is also identified as a crucial need. The preferred technological features for a CTR system tailored for athletes include periodic digital consultations with clinicians, home-based training specific to one’s sport, utilization of technology to monitor workouts, data sharing and remote feedback, personalized exercise recommendations and online educational materials. Conclusion This research explored the user needs and preferences of athlete patients in CR. The findings indicated that enhancing CR for athletes necessitates a personalized and sport-specific methodology. The integration of various technological features within a CTR program can play a pivotal role in assisting athletes with CAD to maintain an active lifestyle and regain their previous athletic performance levels.

The Data-Expectation Gap: A Vocabulary Describing Experiential Qualities of Data Inaccuracies in Smartwatches

January 2025

Many users of wrist-worn wearable fitness trackers encounter the data-expectation gap - mismatches between data and expectations. While we know such discrepancies exist, we are no closer to designing technologies that can address their negative effects. This is largely because encounters with mismatches are typically treated unidimensionally, while they may differ in context and implications. This treatment does not allow the design of human-data interaction (HDI) mechanisms accounting for temporal, social, emotional, and other factors potentially influencing the perception of mismatches. To address this problem, we present a vocabulary that describes the breadth and context-bound character of encounters with the data-expectation gap, drawing from findings from two studies. Our work contributes to Personal Informatics research providing knowledge on how encounters with the data-expectation gap are embedded in people's daily lives, and a vocabulary encapsulating this knowledge, which can be used when designing HDI experiences in wearable fitness trackers.

The commercialization of a growing number of wearable devices has been enabled within recent years due to the availability of miniaturized sensor modalities, the development of new materials, and the scalability of flexible electronics. With the increase in resource shortages within healthcare, there is a demand to translate wearable devices from the commercial consumer stand-point to the medical field. Clinical-grade signal quality, wearability, and comfort all need to be tailored to a wearable design. Wear and comfort for user compliance and durability for longer-term use are commonly overlooked. In this study, the relationship of on-body location and material layer composition is investigated. Five non-woven medical tapes noted for longer wear time are tested over a 7-day timeframe. The impact of material properties, such as elasticity, isotropy, and hysteresis, as well as the moisture vapor transmission rate (MVTR) and adhesive thickness, are evaluated in relation to skin properties on the lower torso of 30, high-activity-level volunteers. User perception was quantified via Likert-scale questionnaires and images were obtained for the material–skin interaction. The results indicate that critical characteristics, such as MVTR and elasticity, noted for positive skin interaction in commercial products, may not translate to improved user perception and durability over time. Future work will assess new design options to manipulate material properties for improved wear and comfort.

While data is the cornerstone of modern design strategies, design researchers frequently struggle when performing data work. This creates a need to design tools that enable design researchers to actively engage with data. However, this presupposes understanding how design researchers create meaning from data representations, as the way of visualizing the data, along with other factors, can significantly impact the extracted insights, increasing uncertainty about the quality of the outcome. As a response to this problem, we explore how design researchers make sense of data in a case study: making sense of paired subjective and objective sleep and stress data visualizations. By synthesizing our findings from two user studies, we construct a sensemaking model which highlights how uncertainty related to data qualities, visualization parameters, and the viewer’s background, affects the insight-generation process. Our findings have implications for the future development of tools and techniques for visual data sensemaking for designers.

... In Figure 1, we propose that if the clinical requirement for wearability is not integrated into the user functional specifications (represented by step T 1 ), the design process will advance to an output design (represented by step T 2 ) that fails to fully address the comprehensive needs of the clinical lifecycle. Issues related to design considerations for longer-term wear need to be considered in the device design process [32,33]. If on-body comfort is missing in the set of functional specifications, the device's ability to meet both user and clinical demands effectively is compromised. ...

... Despite the poster exclusion criteria, two short conference papers were kept since they reported on seemingly relevant innovations like the use of candy [83] and the collaboration between academia and creative industry [86]. Multiple artefacts that were conjunctively discussed in a single record [21,70] were considered singular, for the exception of one record that discussed two data physicalisation artefacts, one as part of a conference and one as part of a series of workshops [98]. As our research concentrated on mature academic contributions, our corpus intentionally comprises records detailing artefacts, given that academic papers generally document the associated construction processes. ...

... However, the BCTTv1 was not specifically developed from a technological perspective, and according to Wang et al. [188], HCI researchers often additionally use terminology from Persuasive System Design (PSD) [132] and Persuasive Technology [55]. One review incorporates the BCTTv1 with other frameworks [85], while others use different classifications and terms for behavior change techniques, such as processes of change [21], persuasive design [135], or a combination of sources [45]. While the lack of consistent terminology can make reporting on techniques difficult, we will use the BCTTv1 by Michie et al. [124] as it is established and comprehensive. ...

... Unfortunately, such 2D touch input does not support direct manipulation of virtual 3D objects in 6 DOFs [9]. Also, multitouch gestures can obstruct user's view [10], and the gesture sets are typically rather complex [11], need to be learned, and often require mode switches during interaction. As an alternative, some previous work has explored haptic props, which can provide direct 3D input [9]. ...
