In this report the development at FOI of a gaze-tracker system is described, both in terms of hardware and software. In the report several gaze-controlled applications are described, both for active and passive positioning. Several of these applications have been implemented and tested. During development of gaze-controlled applications it is important to observe human factor aspects. Therefore a reference group for discussion of these matters has been formed. The group discussions concerning some gaze-controlled applications are described in the report. Head-Mounted Displays, HMD, will in the future network based defence be much more common than today and within different disciplines and applications. The HMD will be more useful when integrated with a gaze-tracker. The development of the gaze tracker described in this report has the purpose to, in the next future step, be integrated with a HMD and also be tested operatively.
