Improving human-in-the-loop simulation to optimize soldier-systems integration.

OBJECTIVE

To identify requirements for human-in-the-loop simulation capabilities and improve their utility in predicting and optimizing soldier-systems integration.

BACKGROUND

Technological development rates within the military are rapidly increasing. Emergent technologies often exclude in-depth consideration of human-system interactions until the physical prototyping phase. Human-in-the-loop simulation tools can allow for earlier consideration of humans in the development process; however, use remains limited.

METHOD

Semi-structured interviews were conducted with key informants to yield perspectives on current human-in-the-loop simulation capabilities and utility specific to the military. An inductive approach to thematic analysis was used to extract critical themes from transcribed interview data. A scoping review was completed to supplement the data obtained from interviews and summarize knowledge regarding requirements for human-in-the-loop simulation and analysis capabilities targeted to the military.

RESULTS

Interviews were conducted with five experts representing the sectors of Vehicle/Equipment Design, Simulation, and Army Research. A total of 2274 sources were identified, and 64 papers were retained for the scoping review. Thematic analysis of the combined data sources yielded six important themes to consider with respect to requirements for future human-in-the-loop simulation capabilities targeting soldier-systems integration.

CONCLUSION

This study has identified eight key requirements to support the use of human-in-the-loop simulation tools to predict and optimize soldier-systems integration and performance.

APPLICATION

Addressing key requirements will improve the ability of current human-in-the-loop simulation tools to accommodate the military's need for human consideration early in the design process.
