 * Write a description of interaction architecture as defined by Mat Hunter** **and Rikako Sakai in relation to their work with Kodak in 1995.**

//**Mat Hunter**//

Mat Hunter explains that Kodak came to the __IDO__ in order to understand the future of digital cameras. According to him there were two main insights; Digital cameras live within the product and service psychology. George Eatman created Kodak by understanding that a consumer has a camera but they press the button and Kodak does the rest which was turning the development of film; a messy hobby with chemicals. He transformed this process into a mass market consumer thing.

According to Mat the second thing we've got to understand is why people take pictures in the first place. We need to understand the underlying user motivations. Photography is a means of self expression and a means of recording information but most importantly than anything it is a social enterprise; its about building social capital. To actually start to visualize where digital camera's are going you need to implement the idea of the social enterprise. They started to tackle what a digital camera would look like by understanding that cameras in the past were only concerned about capturing images but digital cameras included the reviewing, deleting and sharing of images. This prompted the creation of information architecture or interaction architecture; some extensible series of rules that would not only allow one camera to be designed but perhaps a whole series.

Then came the issue of how to communicate these rules, a book could have been a choice but they decided to go with something more experiential which they called a __User Experience Prototype__ which was a big box with a security camera in front. This camera was connected to a Macintosh tower computer and it was running on Macro-media Director. In a few weeks they crafted a user interface on a camera, which allowed you to take a picture and delete and also allowed you to send it across the room to a television set. It was a good insight because it did not only represent function but the feeling of controlling a picture. This prototype was later turned into the __DC210__, the fastest selling camera of its time. Which was the first step to the future of new digital cameras.

//**Rikako Sakai**//

Rikako developed the screen behaviors of __Photo Stitch__ and has been working for Canon for more than 8 years. She was working in the human factor department when she was working on the features of Photo Stitch. In order to create version 3, she tested both version 2 and version 1 through a formal user testing procedure. She used in-house people as test subjects. The most important problem about the versions was that the structure was not visible to the users at all and their were too many steps to stitch. the most important change she made was using interface instead of step by step. This switch wasn't so poplar at first but she added animation for beginners which she discovered was key after some observations.


 * How does the author define 'leading questions' and 'hypothetical questions'? Write a paragraph each to define these terms.**


 * //Leading Questions//**

A leading question controls the outcome of an answer by constraining answer choices. Therefore yes/no answers are simply not sufficient since they don't account for individuals in the middle. Therefore range from extreme to extreme is more suitable.


 * //Hypothetical Questions//**

Ask circumstances users have not considered. These may not be helpful because in deviates from actual usage issues and does not productively help in data accumulation.
