A Reverse-Huffman Algorithm for Text Entry Interface Evaluation
Foad Hamidi, Baljko, Dr. Melanie · Maryland Shared Open Access Repository (USMAI Consortium) · 2012
Scanning or soft keyboards display symbols to be selected when highlighted in an order. People with disabilities use these interfaces to compose text by using one or two input actions. We present a reverseHuffman algorithm (RHA) that extracts a representative latent probability distribution from a soft keyboard design and evaluates and compares it with other designs using the Jensen-Shannon Divergence (JSD).
