We present recent results we have obtained in the design of a wireless tactor system for use in virtual as well as real environments. We describe a system we have designed that uses vibration motors wired to a body-worn control box, which in turn communicates with a host computer using a wireless connection. Though we have successfully integrated this system into an existing VR-based dismounted infantry simulator, it is clear that expanding the body coverage and number of vibration points requires a solution that is completely wireless. To this end, we describe a working prototype we have built that, though still somewhat large and feature-limited, has convinced us of the merit of our approach.

Human Herpes Virus (HHV) is a DNA virus and is the most important viral pathogen causing intraocular inflammation. HHV is classified into types 1-8. Among these types, HHV-1, HHV-2, HHV-3 Varicella Zoster Virus (VZV) and HHV-5 Cytomegalovirus (CMV) are known to cause herpetic viral retinitis, including acute retinal necrosis and CMV retinitis. Herpes viral retinitis can be diagnosed from characteristic ocular findings and viral identification by PCR of the aqueous humor. Recently, therapy has become more effective than in the past. Herpes viral retinitis gradually progresses if appropriate treatment is not provided with regard to the patient's immune status. Further advances in diagnostic methods and treatment are required in the future.
