Portable and immersive display devices abound in modern daily life. Neurological impacts of these devices, positive or negative, are of significant interest for manufacturers and consumers alike. In this talk, I will present recent results from my lab’s application research projects on such impacts. First, neurological side-effects of virtual-reality environments will be explicated in terms of the vestibulo-ocular reflex and its adaptation during use of head-mounted displays. These significantly degrade dynamic visual acuity, and cause neurologic symptoms that could undermine the user experience of such devices. Then, time permitting, the problem of visual glare from mobile phones, especially during night-time use, will be discussed. Psychophysical measurements and monitoring of the pupillary response have yielded results suggesting a control strategy to reduce the annoying visual experience which could also be a serious health threat in the long run.
