Designing a Useful and Usable Mobile EMR Application through a Participatory Design Methodology: A Case Study

An electronic medical record (EMR) supports the general practitioner (GP) in decision-making. In this paper, we report on our study, in which we analyze and identify user requirements for a mobile EMR application. By relying on a participatory design approach, we were able to identify the most relevant patient data for house visits by a GP. Our findings further refine earlier results from similar research by narrowing down the most important information for GPs that should be visible immediately. We also identify five core considerations for the use of a mobile EMR application during a house visit. These five considerations are translated into five requirements: exploiting mobile affordances, immediate availability, quick overview of most relevant data, easy entry of new patient data and the importance of e-prescriptions. We iteratively designed the user interface for a mobile application that meets these requirements. Thus, by taking advantage of the affordances of a mobile device, including context sensing, we optimized the way a GP can use a mobile EMR application.

Optimizing Smartphone Micro-usage with Smartwatch Notifications

In this paper, the influence of a smartwatch application on smartphone micro-usage, brief bursts of interaction [6], among students is investigated. Our study indicates that social applications, such as WhatsApp, SMS or e-mail are used most by students. These applications tend to generate numerous notifications, which often result in brief bursts of smartphone use, which is called micro-usage. We propose three novel ways of handling notifications on a smartwatch, in order to reduce micro-usage. The first proposal receives input through on-screen buttons, the second by tapping the edges of the device and the third by drawing gestures on the screen. An evaluation of our design shows an increase of 5% of application micro-usage and a decrease of 5% of the general smartphone micro-usage.

Quantifying the interaction stages of a public display campaign in the wild

In this paper we present the findings from three exploratory studies in the wild of an interactive public display aiming to increase awareness on cardiac arrest and Cardiopulmonary Resuscitation (CPR). Three different locations (train station, hospital, and university restaurant) were selected in order to understand how context affects the effectiveness of the real-life campaign. For this purpose, we defined and quantified different interaction phases based on the audience funnel and the characteristics of the prototype. Our results confirm that context (location and people) have a direct effect on engagement throughout the interaction phases. A location that clearly relates to the content of a campaign or has an audience that is able and willing to interact will positively influence the outcome of a campaign. In addition, we show that following a model to quantify and compare studies is a feasible and useful approach.

MeViTa: Interactive Visualizations to Help Older Adults with Their Medication Intake Using a Camera-Projector System

In this paper, we investigate whether augmented reality visualization techniques can empower older adults to explore and understand medication information in an effective and timely manner. Through a user-centered design process involving older adults and health professionals we developed an interactive camera-projector system called MeViTa (Medication Visualization Table) that projects medication information surrounding medication boxes laid on a table. Six designs were iteratively developed. In total 26 older adults, with a mean age of 71 (±7), participated in the user studies. Although no time benefits were observed, participants perceived MeViTa as an effective means to explore and understand medication information, and as more engaging than the traditional patient information leaflet. Furthermore, by visualizing medication information, our approach provides qualitative findings of the relative ease and difficulty for older adults to learn more about medication information.

Applying a user-centered, rapid-prototyping methodology with quantified self: A case study with triathletes

This workshop paper discusses how we applied a user-centered, rapid-prototyping methodology to design and evaluate a Quantified Self dashboard for triathletes. Quantified Self barriers as discussed by Li and Forlizzi [1] and Choe et al. [2] are taken into account. A dashboard is designed for and evaluated with in total 25 triathletes and fourteen regular persons. Our results confirm that this methodology is successful and a well designed dashboard can be used to help users analyze their own data.

MyHealthToday: Helping Patients with their Healthschedule Using a 24-Hour Clock Visualization

We propose a variation on the 24-hour clock visualization to represent daily health schedules. The area inside the clock is used to display a graph network which helps patients explore and understand the rationale for each health-related scheduled task, such as taking medication. We investigate whether this visualization can be leveraged to increase patient comprehension of personal health schedules. Two low and one high-fidelity prototype have been designed and evaluated. Participants in our study included both general practitioners and patients. Results are promising and indicate that our visualization can be an effective means to explore and understand health schedules. Moreover, our results suggest there is an actual need for visual exploration of health schedules. Finally, participants perceive that our proof-of-concept provides useful feedback and can help both patients and physicians to discuss and explore health schedules.

Augmenting Drug Discussions in General Practice

This extended abstract discusses our ongoing research on augmenting the communication between an expert and a layman using interactive visualizations. We are currently designing an interactive table that assists patients and general practitioners (GPs) to explore drug information using a camera to recognize drug packages and a projector to visualize complex drug information directly around these packages.

Visualizing quantified self and objective patient data

This doctoral consortium paper discusses our research plans on interactive visualizations of quantified self data combined with the objective data in an electronic medical record. The main goal of the visualization is to support understanding and insight for patients and medical staff.

The involvement of students in the user-centered design process of a mobile health record: a case study

Copyright is held by the author/owner(s). Workshop on designing the future of mobile healthcare support MobileHCI, September 23 -26, 2014, Toronto, Canada. Abstract One of the challenges when designing an electronic health record is the generational difference between general practitioners (GPs), which is especially noticeable when working with mobile devices. We discuss a paradigm shift we discovered when a mobile health record was designed using a user-centered design approach with graduated GPs and evaluated with last year general practice students [1]. Furthermore, we noticed that the usability perception is greatly influenced by the underlying medical registration system used.
