Apparently, Microsoft has been investigating the use of its Adaptive Keyboard for more than 15 years now.
Finally, in 2009, Microsoft finalized its research and described it as an Adaptive Keyboard.
This prototype has a large, touch-sensitive display strip at the top with the display continuing underneath the keys.
But there are a few important differences between the Adaptive Keyboard and the Touch Bar.
For example, lettered keys can change to slide animation tools while editing a PowerPoint presentation displayed on screen.
Secondly, Microsofts touch area displays much larger icons/photos, making it easier to interact with.
Ultimately, Microsoft decided not to develop the Adaptive Keyboard technology.
We did not build computers back then, explained Bathiche, who co-created the Microsoft Surface.
When we did start, we made computers with touch screens.
Whether or not will Microsoft deliver a Touch Bar in the coming years remains to be seen.
