Hunters complain bitterly about GPS ruining their night vision, and all those gadgets using up heavy batteries.
Soldiers have it even worse, carrying, literally, pounds of batteries, sometimes tens of. Anything that works without needing to produce power-burning, night-vision destroying light they have to look at, and weighing them down, is a huge benefit.
- BlueTemplar 5y agoWouldn't they use reflective LCDs ? As low as you want brightness, and tiny power consumption !
- ncmncm 5y agoReflective LCDs are useless in the dark.
- BlueTemplar 5y agoAre they ? I tried to find some information on scotopic visual acuity, but nothing solid... Otherwise, transflective LCDs with red backlight (rods aren't sensitive to red light).
- ncmncm 5y agoFine, but it is strictly better not to need to look. For information more detailed than can be delivered by ambient channels, of course, you need to get it some other way. But audio will often be better than needing to focus on a little display, even if with red backlight.
