BetterKeyboard
Melvin Rudolph Johannes Pfleghar
Typing on small smartphone keyboards can be challenging and uncomfortable. Especially walking or other situations in motion can lead to mistypes. But there is a solution: BetterKeyboard highlights and enlarges most probable upcoming keys, so it is much easier to type fast and correctly. Therefore we implemented an algorithm using monogram and bigram tables to calculate the presumption of letters coming up next. Two versions were implemented. Keyboard 1 highlights and enlarges the 3 most probable keys. The advantage of this keyboard is, that the buttons only enlarge inside their given space and will not change their actual position. Keyboard 2 enlarges or shrinks all keys depending on their presumption. So the keyboard changes size and position of the buttons, this feels natural and floating.
