ItemSelective Sharing is Caring: Toward the Design of a Collaborative Tool to Facilitate Team Sharing( 2023-01-03)Temporary teams are commonly limited by the amount of experience with their new teammates, leading to poor understanding and coordination. Collaborative tools can promote teammate team mental models (e.g., teammate attitudes, tendencies, and preferences) by sharing personal information between teammates during team formation. The current study utilizes 89 participants engaging in real-world temporary teams to better understand user perceptions of sharing personal information. Qualitative and quantitative results revealed unique findings including: 1) Users perceived personality and conflict management style assessments to be accurate and sharing these assessments to be helpful, but had mixed perceptions regarding the appropriateness of sharing; 2) Users of the collaborative tool had higher perceptions of sharing in terms of helpfulness and appropriateness; and 3) User feedback highlighted the need for tools to selectively share less data with more context to improve appropriateness and helpfulness while reducing the amount of time to read.
ItemAffordances of Augmented Reality Systems for Co-Located Collaboration( 2023-01-03)This paper aims to identify relevant affordances towards an augmented reality system for organizational practices of co-located collaboration. As augmented reality is a means to visualize and author information, such an artifact could enable intuitive sharing of information. It can be shown that single aspects are reflected in literature, missing so far is a comprehensive description of relevant affordances for such an artifact. The concept of affordances is increasingly used in information research, as it enables to define design principle based on the action goals of the user. Addressing the lack of clear formulation guidelines of affordances, a proposal is presented of how affordances can be formulated to reduce uncertainty and ambiguity. This paper makes two major contributions: (1) it introduces how augmented reality systems can contribute to organizational practices of co-located collaboration and (2) illustrates how affordances can be utilized to derive requirements for such systems from interviews.
ItemDesigning Mobile Applications for Citizen Participation in Urban Planning( 2023-01-03)As a result of the increasing requirements for urban planning, a paradigm shift towards citizen participation has evolved to collaboratively address enhancing urban challenges and social conflicts. Past projects have examined urban citizen participation processes and methods to support citizen participation. However, the challenges in the domain of informing, encouraging, and enabling participation at any time are not sufficiently examined and less attention was devoted to urban participation through mobile applications, even if required devices are widely used and can enable permanent communication channels between citizens and planning authorities. Therefore, a design science research project was initiated to examine how to design mobile applications to support citizen participation in urban planning projects. In this paper, the findings of the first cycle are presented including issues, meta-requirements, design principles, the development of a mock-up, and its evaluation to provide insight into the design of mobile applications for citizen participation.
ItemCollaborative System Design of Mixed Reality Communication for Medical Training( 2023-01-03)We present the design of a mixed reality (MR) telehealth training system that aims to close the gap between in-person and distance training and re-training for medical procedures. Our system uses real-time volumetric capture as a means for communicating and relating spatial information between the non-colocated trainee and instructor. The system's design is based on a requirements elicitation study performed in situ, at a medical school simulation training center. The focus is on the lightweight real-time transmission of volumetric data - meaning the use of consumer hardware, easy and quick deployment, and low-demand computations. We evaluate the MR system design by analyzing the workload for the users during medical training. We compare in-person, video, and MR training workloads. The results indicate that the overall workload for central line placement training with MR does not increase significantly compared to video communication. Our work shows that, when designed strategically together with domain experts, an MR communication system can be used effectively for complex medical procedural training without increasing the overall workload for users significantly. Moreover, MR systems offer new opportunities for teaching due to spatial information, hand tracking, and augmented communication.
