Rectifeye: a vision-correcting system for virtual reality.

Most head-mounted displays for Virtual Reality (VR) are designed for users with perfect eyesight. Wearing prescription eyeglasses inside such a headset can be uncomfortable, or even impossible if the glasses do not fit (Fig. 1, left). While some headsets offer manual focus adjustment, they need to be manually adjusted for each user through trial and error, and may not fully correct the user's eyesight. A majority of the population wears prescription eyeglasses (e.g., 65% of the American population 1as of 2007). In order to realize the potential of immersive VR, we need to ensure that these users can experience Virtual Reality comfortably while still seeing a clear image of the virtual world.
