The Role of Early User Participation in Discovering Software – A Case Study from the Context of Smart Glasses

Smart glasses facilitate advanced user interaction and increase workplace efficiency through innovation. Yet, their capabilities rely on user-driven discovery of new software that harnesses its benefits. This study investigates user participation during the discovery of new software, leveraging this emergent technology. We investigate user participation during software product discovery, i.e. during early activities that precede classical development and design activities, through an in-depth longitudinal case study with two representative user organizations. The results suggest an evolutionary perspective toward the benefits of different types of user participation: 1) user as a source of information, 2) user as a co-creator, and 3) user as an innovator. Practitioners benefit from our lessons learned, validation and extension of software discovery toward the emergent technology, and recommendations to apply user-driven software discovery. We distill three lessons: evolving types of user participation, enhancing desirability through user participation, and carefully discovering software products for emergent technologies

DESIGNING MHEALTH APPLICATIONS FOR DEVELOPING COUNTRIES

The effective use of mobile IS offers great opportunities for improving health systems in developing countries and enhancing their quality of life. A case in point and, hence, an interesting research subject is Papua New Guinea for being a country with one of the highest maternal mortality rates in the world. Despite the opportunities, many mHealth solutions remain prototypical due to their design and lack of empirical evidence and just little literature discussing success factors exists. To overcome this problem, we derived Design Requirements for the implementation of an mHealth app. We followed a Design Science Research (DSR) approach (a) embedding a triangulation of a literature study, a user survey and on-site observations, (b) working in a cross-cultural and interdisciplinary team and (c) evaluating the Design Requirements ex-ante by taking the example of an mHealth app to support midwives in Papua New Guinea. Practitioners, IS researcher, even design- or behaviourism-oriented, as well as transdis-ciplinary researchers can use the Design Requirement Framework for, on the one hand, design and implement applications in developing countries and, on the other hand, to take single already justified Design Requirements as starting point for a detailed investigation

Mobile Service Support based on Smart Glasses

Emerging technologies, such as smart glasses, offer new possibilities to support service processes. Specifically, in situations where a person providing a service, such as a technician, needs both hands to complete a complex set of tasks, hands-free speech-controlled information systems can offer support with additional information. We investigated this research field in a three-year consortium with partners from the agricultural technology sector. During the course of our research, we 1) analyzed the domain in a multi-method approach to develop (meta-)requirements, 2) proposed design principles, 3) instantiated them in a prototype, and 4) evaluated the prototype. We followed a design science research approach in which we combined the build phase with four evaluation cycles that comprised focus groups, a prototype demonstration, and, based on that demonstration, a survey with 105 domain experts. We address real-world problems in providing information at the point of service and contribute to the methodological knowledge base of IS design and service systems engineering by developing and implementing design requirements and principles for smart glasses-based service support systems

Engineering of Augmented Reality-Based Information Systems - Design and Implementation for Intralogistics Services

The development of augmented reality glasses is still ongoing and faces barriers in diffusion and concerns about their impact on users, organizations and society. The study aims to find sufficient solutions for this struggling digital innovation and to provide guidance for the implementation of augmented reality glasses in design-oriented projects. During a 3-year consortium research, acceptance and privacy have been identified as major phenomena that influence the adoption of augmented reality glasses in the logistics domain. To forge ahead digital innovation research, the focus of the presented research lies on the diffusion of this technology with design knowledge for the development of augmented reality glasses-based systems. Evidence and artifacts contribute to the still limited knowledge of system design based on augmented reality glasses from a domain-specific instantiation and an implementation framework

Gas-Phase Reaction Kinetics of the Ortho and Ipso Adducts 1,2,4,5-Tetramethylbenzene-OH with O-2

The reversible reaction of OH radicals with 1,2,4,5-tetramethylbenzene (1245-TeMB, durene) leads to adducts at the substituted (ipso) and unsubstituted (ortho) positions of the ring. By the use of flash photolysis for production and resonance fluorescence for detection of OH, the gas-phase reactions of O-2 with these adducts were investigated over the temperature range of 300-340 K in He at 200 mbar. The decay of OH, generated by pulsed vacuum-UV photolysis of H2O, was monitored under slow-flow conditions in the presence of 1245-TeMB and O-2 at concentrations of up to 19 X 10(12) CM-3 and 2 X 10(16) cm(-3), respectively. Triexponential OH decays resulted from the unimolecular decomposition of the two adducts, representing OH reservoirs with different stabilities. In the presence of O-2, additional adduct loss pathways exist, leading to faster OH consumption. Triexponential functions fitted to these decays were analyzed to obtain rate constants for the reactions of O-2 with both adducts. Rate constants in the range of (4-13) x 10(-15) and (0.3-3) x 10(-15) cm(3)s(-1) were obtained for the ortho and the ipso adducts, respectively, depending on temperature and assumptions regarding details of the underlying mechanism of adduct isomer formation and isomerization. At O-2 concentrations exceeding about 1 x 10(16) cm(-3), deviations from a linear dependence of the adduct loss rates on the O-2 concentration indicate an even more complex mechanism. The validity of the rate constants is therefore confined to O-2 concentrations below 1 X 10(16) cm(-3). The adduct + O-2 rate constants for 1245-TeMB are greater than the corresponding previously obtained rate constants for benzene, toluene, and p- and m-xylene but smaller than those for hexamethylbenzene. The results are discussed in terms of the current knowledge about the mechanism of OH-induced degradation of aromatic compounds in the presence of O-2

Heuristic Theorizing in Software Development: Deriving Design Principles for Smart Glasses-based Systems

Design knowledge on smart glasses-based systems is scarce. Utilizing literature analysis on software development publications, insights from the design and implementation of four smart glasses-based systems and expert interviews, we elicited 16 design principles to provide guidance in the development of future service support systems. Heuristic Theorizing is an abductive Design Science Research method, hitherto far too little known or little noticed, which was applied to conduct the research. We contribute to theory and practice with applicable design principles to support the development of smart glasses-based systems. Phenomena known to have an impact on the adoption of smart glasses are addressed by these design principles
