I stayed at the New York Hilton this weekend in one of their renovated guest rooms. One piece of technology in the room caught my eye: a sensor-activated light. You step out of bed and LEDs at floor level automatically shine a light across the room. It doesn’t light up the whole room – it’s just enough light to help you find your way to the bathroom in the middle of the night. The light also has a light sensor so that it doesn’t light up when the room has enough ambient light.

It’s a very thoughtful touch.
