with a certain load, then generate a detailed report of the force, torque, and fatigue—can take some time, from three hours to two days. Santos software can take advantage of parallel processing for most jobs, so users with a high- performance computing server running many cores simultaneously will see greater perfor- mance. But optimization formulation remains an area that cannot be parallelized due to the algorithm involved. At the present time, DHM technology em-
ploys a mix of robotic, simulation, and biome- chanical principles. But the demand for more accurate results may push developers to incor- porate a dose of psychology, as well. Malek has a daunting list of requests from his clients in the military; they want him to add cognitive parameters into the software code. "Th ey want to load the digital marine with [inputs such as] being scared, his mood this morning, and whether he's battle-hard- ened," explains Malek. "Th ese soft [inputs] are important to the client, but they are dif- fi cult to model." Th e challenge for Malek as well as other digital human model developers is to fi gure out a way to represent fear, anxiety, state of

takes him a while to respond. He may be in the middle of performing a very crucial task for a client. ■
