The Integrated Soldier System Project (ISSP) is the cornerstone of Canada's future soldier modernization effort, which
seeks to "significantly enhance tactical level individual and team Lethality, Mobility and C4I performance in the
complex, network-enabled, command-centric, effects-based digitized battlespace." This capital acquisition project is
supported by a number of R&D Technology Demonstration Projects within Defence R&D Canada. Several of these
projects focus on the human factors aspects of future technologies, such as IR sensors. The Soldier Information
Requirements Technology Demonstration (SIREQ TD) project examined the performance impact of NVGs, LWIR
imaging systems, and fused systems (both optical and digital fusion) on target detection, recognition and identification.
NVGs were shown to provide good identification performance while LWIR systems excelled in detection tasks. Fused
systems show promise of augmenting the respective stand alone capabilities of each sensor type, but more work is
required to optimize fusion algorithms. The Soldier Integrated Headwear Technology Demonstration (SIHS TD) project
is looking at the human factors aspects of mounting a range of vision enhancement sensors on a helmet, including
optimal placement of both sensors and displays with respect to center of mass, total head borne weight, and visual offset
and parallax issues. Overall headwear system weight should be less than 2.5 kg, and if an offset from the eye is required
then a horizontal offset (vice vertical or oblique) of the sensor appears most acceptable. These findings have implications
on the design of future IR and fused sensor systems for dismounted soldiers.
