"This research compared the relative impact of two approaches for training Basic Rifle Marksmanship (BRM). One hundred and eighty four One-Station Unit Training (OSUT) infantry trainees (i.e., the experimental group) trained under a U.S. Army Reserve (USAR)-developed, device-based (i.e., the Beamhit Laser Marksmanship Training System LMTS) approach, and 202 infantry trainees (i.e., the control group) trained under the standard U.S. Army Infantry School BRM program of instruction. Results revealed that the experimental group outperformed the control group on shot grouping, weapon zeroing, and known-distance firing. No between-group differences were found, however, for record fire qualification scores or for performance during pop-up target engagement practice periods leading up to qualification. The implications of these findings for initial marksmanship training are discussed along with plans for follow-up USAR-sponsored research to assess (a) the impact of LMTS-based training on sustainment performance, and (b) the feasibility of using LMTS-based performance to predict live-fire qualification scores."--Stinet.

This book reports on cutting-edge research into innovative system interfaces, highlighting both lifecycle development and human–technology interaction, especially in virtual, augmented and mixed-reality systems. It describes advanced methodologies and tools for evaluating and improving interface usability and discusses new models, as well as case studies and good practices. The book addresses the human, hardware, and software factors in the process of developing interfaces for optimizing total system performance, while minimizing their costs. It also highlights the forces currently shaping the nature of computing and systems, such as: the importance of portability and technologies for reducing power requirements; the necessity of a better assimilation of computation in the environment; as well as solutions to promote accessibility to computers and systems for people with special needs. The book, which is based on the AHFE 2019 International Conference on Human Factors and Systems Interaction, held on July 24-28, 2019, in Washington D.C., USA, offers a timely survey and practice-oriented guide for systems interface users and developers alike.
