Future is coming.......

I never think of what the role of interface design will be when computation has been spared though out and embedded in everything in the environment. Like the author mentions, the invisibility is a challenge and an optimal goal for computation. It will happen within just a matter of time, sooner or later. To solve this problem, besides the traditional HCI approach, the design perspective needs to move forward to focus on engaging the user experience and considering social settings. After understanding what people do, and then we will have the chance to make the invisible interface. I personally think the Design Communicates is very important for interaction design too, especially in a group work setting like CSCW. It’s another challenge that how we can use the system design and develop to help people communicate more effectively among group members, not just being fast but also helping create meaningful interactions for them. Essentially, there are "a lot" more concerns when designing system for a group of people. Anyway, I am still on my way trying to figure it out.
