Aims:
  1. Human-Computer Interaction with Multi-Monitor Consoles: Determine the optimal balance between number of display units and number of display formats for display format navigation. Determine optimal default configurations to minimize display navigation. Synthesize all data to form recommendations for optimal configurations for different scenarios.
  2. Color Coding: Determine optimal use of color coding with text and graphics using the caution and warning domain as a case study.
  3. Readability under Vibration: Build upon FY09 investigations on the effects of vibration on visual performance: continue research in the vibration facility, focusing on overall text readability, optimal font size, optimal line spacing, and understanding the effects of peak versus continuous vibration.
  4. System Health and Status Indicators: Through literature review, determine a small set of promising approaches for indicating health and status in displays having constrained real estate. This would serve as pre-work for a potential future-year research effort.
  5. Speech Alarms and Effects Of Alarm Source: Build upon FY09 work, expanding the investigation of speech alarms as primary and secondary alerts. Include the impact of the alert source (speaker, headset).
  6. Effects Of Vibration on Speech Intelligibility: Build upon the FY09 speech analysis and complete a study of speech intelligibility under different levels of vibration.
  7. Spatial Auditory Displays: Build upon FY08 initial development efforts in ambient auditory displays for situational awareness (SA) to conduct an evaluation of a prototype spatial auditory display that enhances SA and provides navigational cues during suited operations.

The Displays Development project completed all aims, contributing to closure of the HCI guidelines gap. Using a caution and warning paradigm in order to complete a set of procedures, the effect of multi-monitor usage and color coding was explored. In order to understand the influence of vibration on reading performance, several ground studies was conducted examining the effects of peak versus extended vibration on readability as well as examining the effect of strobing as a countermeasure to vibration effects on reading. In addition, an in-flight study was conducted in which crewmembers judged different font sizes and other text characteristics during a shuttle launch. Several studies examined of the feasibility of speech alarms and spatial auditory displays. Results from all studies are appropriate for inclusion in the Human Interface Design Handbook (HIDH) in the form of recommendations and guidelines.
