Toward minimal latency simulation systems
Ronald Moore, Charles Pope, Eric M. Foxlin · 1998
The careful integration of new hybrid tracking sensors and improved motion prediction algorithms, along with advanced image generation features such as pre-draw insertion of sensor data and image shifting, can provide simulation system developers with far greater flexibility (using COTS hardware) to find the optimal balance between cost, database complexity, display resolution, and acceptable levels and types of image artifacts without compromising system latency or accuracy. Personal Computer based data acquisition boards used in conjunction with the Electronic Visual Display Attitude Sensor (EVDAS) has led to the development of a comprehensive and portable latency measurement evaluation system for simulator troubleshooting, and for verifying that latency minimization goals are achieved. Minimal latency systems are not only needed hi order to more fully meet new military training goals of greater fidelity, affordability, and deployability, but to transfer new technology to commercial and private use markets without health and safety risks and their concomitant liability.
