This document discusses the future of user interfaces. It begins by defining the user interface as the means by which users interact with computer systems, using input devices and software. It then explores why interfaces are changing, noting that users have changed and are increasingly mobile, and that design must refocus to account for these changes. The document suggests two potential future interfaces: graphical user interfaces, which will continue to evolve; and voice user interfaces, which analyze speech using techniques like hidden Markov models and may become primary interfaces for human-computer interaction.

10. USERS HAVE CHANGED
For a long time, we've been using a traditional way of working
with media. We have a desk, a computer and the keyboard
and mouse as input-devices.

20. Hidden Markov Model
1.Each phoneme is like a link in a
chain, and the completed chain
is a word
2.The chain branches off in
different directions as the
program attempts to match the
digital sound with the
phoneme that's most likely to
come next.
3.The program assigns a
probability score to each
phoneme, based on its built-in
dictionary and user training.
