Perhaps an experiment: Go outside in the sunlight and hold your hand out and see how much IR heating you can feel. Then come back inside and hold your hand over your IR Touchscreen and see how it compares to what you felt outside, and experience every sunny day.
(Note: Experiment may not be possible in Vancouver.)
Luck;
