“Augmenting a camera with a thermometer”

All of today’s digital cameras record the date and time at which a photo has been taken; some cameras also record the geographical position. This work proposes yet another augmentation: to record temperatures at different spots picked by the user in the image. This has many applications for both family life and professional engineering: Was the water in the swimming pool heated? Was last Saturday night’s party fever really a fever? On the serious side, an engineer may record the temperature of different chips on a printed circuit board or document heat loss due to bad building insulation.
