Many parents who take trips on the road will call home and talk to their kids every day. That's great, but it deals with only one of our five senses, sound. Now a group of scientists in Singapore are developing a way to add a sense of touch to the experience. The group's "cyber pajamas" can relay the warmth and feel of a faraway person's touch by regulating pressure and temperature over different parts of the garment. This way, the parent can give their kid a cyber hug from across the globe. While this all sounds innocent enough, I can also envisage developments of the technology having great appeal to some of those 976 numbers.
