The design model is the conceptualization that the designer has in mind. The user's model is what the user develops to explain the operation of the system. Ideally, the user's model and the design model are equivalent. However, the user and designer communicate only through the system itself: its physical appearance, its operation, the way it responds, and the manuals and instructions that accompany it. Thus the system image is critical: the designer must ensure that everything about the product is consistent with and exemplifies the operation of the proper conceptual model. All three aspects are important. The user's model is essential, of course, for that determines what is understood. In turn, it is up to the designer to start with a design model that is functional, learnable, and usable. The designer must ensure that the system reveals the appropriate system image. Only then can the user acquire the proper user's model and find support for the translation of intentions into actions and system state into interpretations. Remember, the user acquires all knowledge of the system from that system image.

"the term affordance refers to the perceived and actual properties of the thing Affordances provide strong clues to the operations of things" for example, a door can have the affordance of 'openability' it should tell you how to open the door, right? but look at the picture, the handle is a hand, should I push it, pull it, or.... shake it?
T is the average of the total operation time. D is the distance from the starting point to the center of the target. W is the width of the target measured along the axis of motion. The Start button in Windows is seemingly located in an ideal place for fast acquisition, and in recent versions of Windows that’s certainly true. Prior to Windows 2000, however, the Start button had a single “dead” pixel along the left and bottom sides of it in which clicking didn’t open the Start menu. The result: slower acquisition times and a startling number of missed clicks.
GUI easy to program lowcost ex. iOS, Android, but TUI more natural physical property sometimes they are difficult to choose which is better
they combine the smartphone and the book, so we can still flip the page, but its contents are more dynamic, also, the smartphone has a lot of sensors, ex microphone, accelerometer, touch-screen combine with books will be more interesting and more participating
Author: David Merril, Jeevan Kalanithi (both from MIT Media Laboratory, Cambridge, MA) Year: 2007(paper), 2009(TED) From: MIT Media Lab Paper: Siftables: Towards Sensor Network User Interfaces, 2007 ACM Website: http://sifteo.com/ every block have small screen, accelerometer, infrared sensor, they can sense how many blocks are connected, 4 sides, so 4 blocks at most children are easily to construct these blocks, also, because of the accelerometer, these blocks can simulate tilt motion like pouring, merging colors, etc.
They also had a great presentation at TED, we can watch it later:) we have seen two examples for children, now let's talk about the elders.
they can drag and drop between the screens
actually children and elders have something in common. For example, they may not familiar with computers. especially to elders, their eyesight is poor. they can't type keyboard on the phone, so sms, email is not work for them, but for us, we often use these things to communicate with each other
