Researchers have explored the theoretical minimum number of keys required for text entry by leveraging advanced language models. Their study found that a 3-key input system, when combined with GPT-4o for disambiguation, achieved a character error rate of 9.46%. This represents a significant improvement over 2-key systems, which had a much higher error rate. The findings suggest that 3 keys are a practical minimum for general English text entry in offline settings with strong language model priors. AI
