Matt Jones recently wrote a feature in Interactions that talks about expressive computing. He is disappointed that a lot of our technology is causing us to have less interaction with those around us. How many times have you been in a room with 10 people, all yapping away on their cell phones or absorbed in their smart phones and not noticing the real world around them.
Rather than recommending we give up our toys, he talks about some great apps (some real, some imagined) that we can use to put us back in touch with our surroundings and make the experience even better. He talks about supporting our imaginations and giving us richer real world experiences.
It's a great message. I hope his projects come to fruition and/or he motivates others to take on his message.
