arXiv:2606.11642v1 Announce Type: cross Abstract: How far can we reduce the number of physical keys if we endow an ambiguous keyboard with modern language models? Fewer keys increase hardware design freedom in constrained settings such as assistive devices and mobile form factors. This paper systematically evaluates text entry systems using 2-5 physical keys combined with language-model-based disambiguation. On a 300-sentence English corpus (100 sentences each for Business / Conversational / Technical), we compare key counts (2-5), letter-to-key mappings (layout-based / frequency-based / inten
Advances in language models are enabling new approaches to human-computer interaction, specifically in constrained input environments.
This research explores a fundamental constraint in hardware design—input keys—and demonstrates how AI can overcome it, expanding design possibilities for various devices.
The theoretical minimum for physical keys in text entry is being explored, potentially leading to new keyboard designs and accessibility solutions.

- · Mobile device manufacturers
- · Language model developers
- · Hardware designers
- · Traditional keyboard manufacturers (long-term, marginal)
- · Input methods relying on many discrete keys
Reduced key counts in physical interfaces become viable due to AI-powered disambiguation.
This could lead to smaller form factors for devices or new types of human-computer interfaces.
These innovations might make complex devices more accessible for disabled individuals or enable novel interfaces in AR/VR.
