But I need some help, folks. I would like to present a list of the current non-speech interfaces to cell phones, and the list seems rather short. Cell phones have keys, keypads, buttons, and joysticks. Some have Bluetooth-based virtual keypads, although I can’t say I’ve seen one in use; and Apple’s iPhone will have a touch screen. (Some cell phones have speech recognition interfaces, but I’ve rarely seen one in use.)
I’d like to include other up-and-coming interfaces for the cell phone, either commercially available or close to deployment. If you’ve a suggestion about a technology to mention, please let me know by leaving a comment here.
