Just to note this very interesting article in today’s IHT: Making next popular cellphone can be study in psychology. How do we design a phone to make it not just desirable, but also so that it adds maximum value to the user’s lifestyle? Through observation…  I like the point about noting that Chinese users were observed using the light from their phone to help unlock doors in unlit areas (but is this in any way unique to China? Doesn’t everyone do this?). It reminds me of something I read somewhere, now forgotten, saying that where rock fans once held their lighters in the air at concerts, they now hold up their mobile phones. Not something I would know from personal experience, but it makes me wonder what a phone designed for rock fans might be like!
