That “language model” and the keyboard itself would also adapt to your own writing patterns. As you’d type, the hit areas of the letters would dynamically change to adapt based on the previously typed letters and your typing history. For example, if, when typing a word, you consistently would hit between two keys when only one made sense, it would increase the hit area of the key you meant to hit and decrease the other.
