While you might not hear that much news on the patents that RIM files, you can be sure that the company is busy churning out new ideas too and its latest patent filing with the USPTO describes a “multi-tap keyboard user interface”. The system would be a great boon to the visually impaired, as it offers an auditory feedback system, allowing users to invoke applications by hitting a specific set of keys, each with a specific audio message, helping the user to navigate the device effectively. If such a functionality would be built-in to BlackBerry devices in the future, it should be quite helpful to the folks who need it.
