Methods and systems for text input are provided. In one example, a head-mountable device (HMD) having a touch interface may be configured to receive touch inputs from a user to enter text. The touch interface may include input areas corresponding to characters. The HMD may be configured to determine characters and words the user wishes to enter according to different touch inputs, including land inputs, lift inputs, flick inputs, drag inputs, tap inputs, and scratch inputs. In one case, the HMD may determine subsets of characters for each letter in a word the user wishes to enter, and determine the word the user wishes to enter according to the subsets of characters. In another case, the HMD may determine a vector array corresponding to the word the user wishes to enter, and determine the word the user wishes to enter by comparing the vector array against word vector templates.
