Jeff Han

Jeff Han came up with a multi-touch interface design. It has a multi-touch censor which allows someone to touch with more than one finger at a time. A great thing about his design is that it is high resolution, low cost, and very scaleable. His design has a lava lamp application where someone can move around the blobs and create heat in them. Han's design also has a virtual photo-editing tabletop that is very interesting. Someone can move, enlarge, and break apart photos. His design would be a great, new way to interact with machines. It would be much more interesting and it would be a quicker way to do things. There is a keyboard on the design and it is made so that it can resize to a person's hands. One really cool application is the world application. A person can zoom in to any part of the world they want and see cities, rivers, and even roads. Someone can draw something on this interface design and it will change into a character, which is really neat.

Jeff Han's multi-touch interface design is very creative and fun in a lot of different ways. There are many applications where someone could move stuff around and have fun with. If machines could have the multi-touch technology, things would probably be much easier and less complicated.

William Kamkwamba

William Kamkwamba was 14 years old when he got an idea to make a wind mill. He got and read a book about enery and wind mills. He tried to make one and was successful at it. The book that he read used three plates, but when he tested his wind mill, he used four and found that more plates gives more power. The wind mill provided electricity for the home. It lit the lights and it gave electricity to the radios. Kamkwamba says that he wants to make another wind mill to irrigate the crops for the whole village. He wants to continue learning and doing things with energy.

Kamkwamba was very generous to build this wind mill. It probably helped his family a lot by providing electricity for their home.
