Abstract: Failure to address extreme environments constraints at the human-computer interaction level may lead to the commission of critical and potentially fatal errors. This experimental study addresses gaps in our current theoretical understanding of the impact of ±Gz accelerations and field dependency independency on task performance in human-computer interaction. We report the results of a controlled experiment, conducted in an aerobatic aircraft under multiple ±Gz conditions, showing that cognitive style significantly impacts latency and accuracy in target acquisition for perceptual-motor tasks in altered ±Gz environments and propose design guidelines as countermeasures. Based on the results, we argue that developing design requirements taking into account cognitive differences in extreme environments will allow users to execute perceptual-motor tasks efficiently without unnecessarily increasing cognitive load and the probability of critical errors.

Abstract: An increasing number of low and middle-income countries are receiving significant investments to implement health reform strategies featuring a health management information system (HMIS) as a fundamental eHealth intervention. We present the case of Morocco's first step toward the implementation of a national HMIS: the urbanization of its health information system — an information architecture methodology designed to leverage existing capacity while ensuring sustainability of the new HMIS. We report on this process and share lessons learned, applicable to similar countries involved in HMIS interventions, including involving all stakeholders from inception to rollout, encouraging local ownership of the new HMIS, fostering active data usage among users, and leveraging existing personnel rotation policies when developing adoption strategies and facilitating capacity building efforts.
