A Vision of Computing From Microsoft's Future Thinker
CNN (12/03/09) Voigt, Kevin

Over the next 10 years, how people interact with computers will evolve drastically, with hand gesture controls becoming as common as keyboards, and file selection being determined by eye scans instead of mouse movements, predicts Microsoft chief research and strategy officer Craig Mundie. "Today, most people's interaction is through a screen--whether they touch it, type it, point or click, it's still just graphical user interface," Mundie says. "While that's very powerful and has a lot of applicability, I think it will be supplemented in dramatic ways by what we call a natural user interface." He says computers will soon be able to emulate the human senses of sight, hearing, speech, touch, and gesture, and combine them in multiple ways for people to interact with machines. The interactivity revolution will be fueled by new multiprocessor computers, which are expected to be widely available by 2012. Mundie says these new processors should provide a major performance gain, with some performances increasing by a factor of 100. One of the first major commercial applications of the new interface technology is expected to be released next year when Microsoft launches its new line of Xbox gaming consoles, which will completely eliminate the need for handheld controllers. Mundie says the new gaming interface enables players to move and use gesture controls, with the system calculating in real time the angular position of the 22 major joints in the body. Mundie envisions a day when users will simply be able to talk to their computers about solving problems. "You should be able to describe the problem or the policy you want and the computer should be able to somehow implement that," he says.

And a student sent me this link about an augmented reality system called SixthSense

Here is the spec for the seventh programming assignment

Here are some hints for project 7

• A student was writing to the weblog successfully, but when he killed his server using C, the weblog was empty. This was because all of the writing was buffered. After writing to the weblog, call fflush (if you opened the file with fopen())
• In your client make sure that you append two newlines to the get request; otherwise the server will be waiting for the second newline.
• It is OK to display the temp file (or whatever you call it) when the client send a / request.
• Your server should check the request to make sure that the client is not requesting a file that begins with the parent (..). It should take about three lines of code to check for this, and it is a potential security loophole.
• A browser might ask for a favicon. A favicon is a small image (often 16 x 16 or 32 x 32) which is sent to the client. This is displayed in your favorites or bookmarks menu. They often have a .ico suffix, but may also have a .png or .gif suffix. You can either have a small favicon in your server directory and send it, or send a 404 message.
• If you use the daemon function which I provided, keep in mind that this closes standard output and standard error, so any error messages which you are writing to standard error will be sent to /dev/null, the bit bucket. You can comment out the code that closes all of the file descriptors. Also, make sure that you comment out the line that changes the directory to root. If cntl c does not kill your server, you can run ps to get the process id, and then enter this command at the shell.
  kill -9 processid
  
• If you are having problems with your client, you might want to attach one or both of these headers. The double newline comes after all the headers.

  GET / HTTP/1.1
  Host: www.cs.rpi.edu
  Connection: close
  
  

  The first is required by some web sites, the latter is needed to make sure that read or recv will return 0 at the end of the message. Replace www.cs.rpi.edu with the name of the server that you are trying to connect to.
