In the past, we have used monocle (one-eyed) displays to create the overlay effect desired for augmented reality. Here are instructions that may be used to successfully hack your Sony Glasstron into a monocle display more useful for augmented reality and other around-the-lab experiments. Without further modification, we find that the Sony Glasstron is still too power consumptive for everyday use (~2hrs / 1 NP-F950). However, the Glasstron does feature a proximity sensor on the head-band that controls display and backlight power. Even though the display powers down, the VGA converter, user controls, and base unit cooling fan remain powered up.
