The challenges of the interface is what Negroponte dwells on this chapter. For the years to come it is not just giving people better sound quality, bigger screens, easier to use graphical input devices but to make computers that know you, learn about your needs and understand verbal and non-verbal languages. It should know the difference between you saying two different things that sound alike. Not because it can find the small acoustic difference but because it can understand the meaning. As Negroponte states--that's a good interface design. The idea of having computers that are more like people.

CHAPTER EIGHT

Ivan Sutherland's Ph.D. thesis of "sketchpad" was the idea explosion of interactive computer graphics. Sketchpad was a real-time line-drawing system that allowed the user to interact directly with the computer screen. Yet after the next ten years or so reseachers started to lose interest in the real-time interactive aspects of computer graphics and went into synthesizing more realstic images, off-line and not real-time. During the same time the author realized that the comfort and ease which humans could express their graphical ideas were more important than the machine's ability to render them as synthetic photographs. Pixel is the molecular level of graphics taken from the words picture elements.

CHAPTER NINE

Virtual Reality or VR pemits people to experience a certain situation with one's own body. Its aim is to deliver a sense of "being there" in a situation or make an image change depending on your point of view. It has only been lately that we refer VR as a consumer entertainment medium. VR was formerly used for space exploration and other military applications.

CHAPTER TEN

Computers that function as eye sensors wherein eyes to point at something and combined with a head gesture, is an extremely powerful channel of communication and lifestyle chaging as well. Sooner or later the fingers will be used as our current mouse. Though this idea is yet to be accomplish dut to the difficulty of finding a good technology for sensing the near field of the finger. And also add these three statements mentioned by Negroponte: You cover what you point at when you point at it. Your finger is low resolution. Your finger dirties the screen.

CHAPTER ELEVEN

Typing is not an ideal interface. If we could speak to our computers freely and transcribe our words into text, the better. The primary reason for so few advances in speech recognition is lack of perspective, but not the lack of technology. It also states that we have overlooked the value of speech beyond words.

CHAPTER TWELVE

Target Market, this concept is changing the way how an interface is designed and suitably customized/personalized, a certain niche developed. The objective is to filter information being presented and put more attention and information to those that are selected and suit your needs or just concern you. In the distant future, interface agents will read, listen to and look at each story in its entirety. In the near future, the filtering process must happen by using headers, those bits about one bits. Our interfaces wull vary. Yours will be different from mine, based on our respective information predilections, entertainment habits, and social behavior-all drawn from the very large palette of digital life.
