Make it usable: Highlighting the importance of improving the intuitiveness and usability of a computer-based training simulation

Abstract

Usability refers to the ease-of-use, learnability, and satisfaction of an individual's interactions with an interface. With the increased fielding of constructive simulation and personal computer-based simulation for training, there is a growing need for proper usability evaluations during the developmental phase of a product's lifecycle to ensure higher rates of effective use, understanding, and trust from targeted users. The Linguistic Geometry Real-time Adversarial Intelligence and Decision-making (LG-RAID) computerbased training simulation was designed as a training simulation for Army personnel undergoing training on the development of tactically correct courses of action. A heuristic evaluation was conducted to identify strengths and weaknesses of LG-RAID's User Interface (UI) design. Results are presented and discussed with a focus on the importance of being mindful of the cognitive capabilities of the user when designing UIs, understanding and executing simulation design needs based on these capabilities, and the benefits of integrating those design changes during development.
