8. A method comprising: receiving, by a text-entry device comprising a processor, a selection of a key of a plurality of keys, wherein the key is associated with a question and wherein the selection of the key indicates an answer to the question; after receiving the selection of the key of the plurality of keys, assigning, by the processor, a prediction value to at least a portion of the plurality of keys based on the answer to the question associated with the key selected; and adjusting, by the processor, an acceptable angle for one of the at least a portion of the plurality of keys relative to the prediction value assigned to the one of the at least a portion of the plurality of keys, the acceptable angle being measured by a plurality of contacts arranged around a center of the one of the at least a portion of the plurality of keys, the plurality of contacts comprising a plurality of upper contacts and a plurality of lower contacts, wherein adjusting the acceptable angle comprises: in response to the one of the at least a portion of the plurality of keys being assigned a lower prediction value, increasing a number of the plurality of upper contacts of the one of the at least a portion of the plurality of keys required to contact a number of the plurality of lower contacts of the one of the at least a portion of the plurality of keys to constitute an entry of the one of the at least a portion of the plurality of keys, and in response to the one of the at least a portion of the plurality of keys being assigned a higher prediction value, decreasing the number of the plurality of upper contacts of the at least a portion of the plurality of keys required to contact the number the plurality of lower contacts of the one of the at least a portion of the plurality of keys to constitute the entry of the one of the at least a portion of the plurality of keys, wherein the plurality of keys is coupled with the text-entry device.
13. The method of claims 8 , further comprising resetting the plurality of keys such that the acceptable angle of each of the plurality of keys is substantially similar.
