Designers spend more resources to develop better mobile experiences today than ever before. Researchers commonly use visual search efficiency as a usability measure to determine the time or effort it takes someone to perform a task. Previous research has shown that a computational visual saliency model can predict attentional deployment in stationary desktop displays. Designers can use this salience awareness to co-locate important task information with higher salience regions. Research has shown that placing targets in higher salience regions in this way improves interface efficiency. However, researchers have not tested the model in key mobile technology design dimensions such as small displays and touch screens. In two studies, we examined the influence of saliency in a mobile application interface. In the first study, we explored a saliency model's ability to predict fixations in small mobile interfaces at three different display sizes under free-viewing conditions. In the second study, we examined the influence that visual saliency had on search efficiency while participants completed a directed search for either an interface element associated with high or low salience. We recorded reaction time to touch the targeted element on the tablet. We experimentally blocked high and low saliency interactions and subjectively measured cognitive workload. We found that a saliency model predicted fixations. In the search task, participants found highly salient targets about 900 milliseconds faster than low salient targets. Interestingly, participants did not perceive a lighter cognitive workload associated with the increase in search efficiency.

“…Because BASALT simulated communication latency and employed IV positions, SCICOM communicated with IV, not EV. Communication with IV was done via text using Playbook's mission log (part of the Minerva software suite which enables timeline management and creation, traverse planning, data collection and archiving, and procedure management [Marquez et al, 2013, 2019]). Delayed text communication with IV meant that some aspects of the SCICOM role used in an analog like DRATS, where communication was real-time through voice (Eppler, 2013), were necessarily transferred to the IV team.…”

Developing Intra-EVA Science Support Team Practices for a Human Mission to Mars

During the BASALT research program, real (nonsimulated) geological and biological science was accomplished through a series of extravehicular activities (EVAs) under simulated Mars mission conditions. These EVAs were supported by a Mission Support Center (MSC) that included an on-site, colocated Science Support Team (SST). The SST was composed of scientists from a variety of disciplines and operations researchers who provided scientific and technical expertise to the crew while each EVA was being conducted (intra-EVA). SST management and organization developed under operational conditions that included Mars-like communication latencies, bandwidth constraints, and EVA plans that were infused with Mars analog field science objectives. This paper focuses on the SST workspace considerations such as science team roles, physical layout, communication interactions, operational techniques, and work support technology. Over the course of BASALT field deployments to Idaho and Hawai‘i, the SST team made several changes of note to increase both productivity and efficiency. For example, new roles were added for more effective management of technical discussions, and the layout of the SST workspace evolved multiple times during the deployments. SST members' reflexive adjustments resulted in a layout that prioritized face-to-face discussions over face-to-data displays, highlighting the importance of interpersonal communication during SST decision-making. In tandem with these workspace adjustments, a range of operational techniques were developed to help the SST manage discussions and information flow under time pressure.

“…In order to study crew self-scheduling during long duration space missions, astronauts need a tool that allows them to manage their schedules without depending on interaction with mission control. Playbook is a user-friendly, mobileready, comprehensive software tool that enables astronaut crews to manipulate and execute mission plans [8,9]. At its core, Playbook is comprised of a mission Timeline that displays the scheduled activities for all crewmembers on any given mission day ( Figure 1).…”

Through Playbook, a planning and scheduling software tool, we have incrementally enabled the capability for Earth analog mission crews to modify their schedules at various levels of complexity. Playbook allows the crew to create new activities from scratch, add activities or groups of activities from a Task List, and reschedule or reassign flexible activities. The crew is also able to identify if plan modifications create violations, i.e., plan constraints not being met. This paper summarizes our observations with qualitative evidence from four NASA Extreme Environment Mission Operations (NEEMO) analog missions that supported self-scheduling as a feasible operational concept.
