A team in Germany has come out with a cool front-end Keyboardr for the search engines on Google, Wikipedia and YouTube. Keyboardr will display and execute the searches while you type. It is a better interface in comparison to traditional type-wait-retype techniques that most of the search engines have.
It will also navigate your results with the keyboard that will provide a speedy search option to users.
Nobody is sure that using Google this way is legal or if the technology will be able to attract mass users. A typical Google search method is known to be more compute-efficient in comparison to searching on every typed letter. But this new Keyboardr method might prove efficient for users as it will let you see and refine the search as you go.
