These circuit card assemblies were designed in support of a virtual reality system under a development contract with the Hawaii National Guard.
WTSi designed and built four unique circuit cards in support of a very sophisticated virtual-reality training platform for military applications.
These boards provide the user with electrically-controlled 'eye alignment' within the headgear as well as provide the 60Ghz video link (via third-party RF modules) for display within the headgear.
