Last Friday software developer BlindType announced in a blog post that it has been bought by Google.

BlindType makes software that it plans to sell to mobile device manufacturers and mobile OS makers. The software aims to bring tactile feedback back to typing on mobile devices, which was lost with the introduction of the touch screen that doesn't offer such feedback, the company explains.

Existing prediction and auto-correction software requires that the virtual keyboard be fixed at a predefined location on a device's touch screen, therefore forcing the user to have his or her full attention on the screen while typing ... but still end up with spelling errors and typos not caught by correction software.

Combine these factors with the tiny keys of mobile device touch screens and the result is a frustrated user.

"We know that typing on your mobile device can be a frustrating experience, which is why we've worked hard to make touch typing easier and faster than ever - the way it should be," reads the BlindType blog post.

The company attempts to do this by developing software, which hasn't yet been released, that understands when a user's input is not an error, but that the user touched the screen in a certain spot for a reason, and figure out what that reason is. By automatically adjusting to the user's "perceived" keyboard and style of typing, the system eliminates typing frustrations, says the company, and allows for "super sloppy typing largely without looking at the screen, for the first time," hence the name BlindType. The company says users can type faster and more easily "the way they are used to - no gestures, nothing new to learn."

"We believe that programs that adaptively extract the maximum information from the minimum user input are going to be the future of interfaces," say officials.

Apparently Google has purchased BlindType to integrate the software into its Android mobile OS. The value of the acquisition was not disclosed.
