Deleterious Effect of Participant Positioning on the Acceptability and Acceptance of a Wellness Management System under Development

Managing everyday wellness using sensors requires user buy-in and acceptance. The Unified Theory of Acceptance and Use of Technology (UTAUT) was used to measure at D-0 the acceptability (a priori), and at D-21 the acceptance of an ambulatory monitoring system under development, the SHERPAM system. Interviews with the participants revealed that they no longer viewed the system in the same way at the different stages of the study. The results of the qualitative analysis suggest that the time of the research led the participants to stop seeing themselves as potential future users and to take on the role of critical testers of the technology (which corresponds more to a user test). This role change led participants to question the usefulness of the technology, which affected their intention to use the technology in the future (5.30 vs. 4.24; t = 2.58 *). This research identified the reasons why it was crucial to have a fully functional device in the second phase (acceptance study). The results of this study suggest that it is inappropriate to undertake an acceptability study when the technology is under development. While the SHERPAM platform has been the subject of several user tests, none have been carried out in a situation of use. Thus, this study seems to suggest that the dysfunctions observed are more related to the absence of a development phase in the daily activity of the users. Thus, to ensure a good appropriation of the technology and to predict its use, the technology must not only be in perfect working order, but must also have been developed according to the daily activities of the individuals.

There is Always a Way: Organizing VR User Tests with Remote and Hybrid Setups during a Pandemic—Learnings from Five Case Studies

(1) COVID-19 pandemic restrictions caused a dramatic shift in research activities, forcing the adoption of remote practices and methods. Despite the known benefits of remote testing, there is limited knowledge on how to prepare and conduct such studies in the industrial context where the target users are experts and company employees. (2) In this article, we detail how we organized VR user tests in five industrial cases during the pandemic, focusing on practicalities and procedures. We cover both on-site testing, including disinfecting and other safety protocols, as well as remote and hybrid setups where both remote and on-site participants were involved. Subject matter experts from eight countries were involved in a total of 22 tests. (3) We share insights for VR user test arrangements relevant to the pandemic, remote and hybrid setups, and an industrial context, among others. (4) Our work confirms that with careful planning it is possible to organize user tests remotely. There are also some limitations in remote user testing, such as reduced visibility and interaction with participants. Most importantly, we list practical recommendations for organizing hybrid user tests with safety and disinfecting procedures for on-site VR use.

User Task Scenarios for Map-Based Decision Support in Community Health Planning

Health outcomes are affected by the socio-demographic and physical-environmental characteristics of the places where people live. Therefore, epidemiologists have been interested in the use of maps to explore spatial patterns of disease for a long time. Geographic Information Systems (GIS) are not only useful when visualizing complex spatial datasets but also when mapping the results of analytical processes. One such process is multi-criteria evaluation (MCE), which can be used to generate composite measures of public health based on individual, medical and non-medical factors. The objective of this study was to determine if geovisual MCE can be an effective tool in community health planning. We provided highly interactive thematic maps coupled with MCE tools to planners at a community health centre and evaluated their use for community health planning and decision-making. User task scenarios were designed in a way to compare the usefulness of different representation methods for a number of tasks. The pilot user test with two expert participants included interviews, questionnaires, and user task scenarios with think-aloud audio and screen video recording. We assessed the easiness of completing the tasks using completion rates and times and could identify a number of specific usability issues with the tool at hand.

Development and evaluation of a handheld type 6 DoF midair haptic device using asymmetric vibration and a presentation force vectoring mechanism

This paper describes a handheld type aerial haptic device with 6 DoF (degree of freedom) using pseudo-haptics by asymmetric vibration. By introducing a original presentation force vectoring mechanism, 6 DoF force sense presentation and compactness suitable for handheld use with a small number of vibrators are realized together. In addition, a relationship between the drive input and output (presentation force sense) of the developed device is formulated, and its inverse problem solving method for obtaining the drive input that realizes a desired presentation force sense is derived. Furthermore, a user test clarified the direction in which this device can / cannot effectively exert force.
