I wonder what discipline can emerge from the future battles over ownership of the field. Maybe HCI is as complex as the human experience thus each discipline encompasses a core fundamental function of the brain. Hopefully there will be a discourse among the leaders in the field in order to identify core concepts that will be shared.
I wonder where is the visual and experiential designers role in all of this. As an industrial design I did interaction design when I designed web sites or designed a first class airline seat for an airline. It was called human factors when I was an undergrad and usability as an MFA candidate. Who will speak up for the designers in this process?
I wonder if the success of applications such as Azure is a result of creating access for other disciplines to have a ramp into this field.
