Abstract

A peripheral display supports audible voice commands that describe operational states to aid in use of the peripheral display by a disabled person with a dongle that receives strings of text for translation to voice that is played at a speaker. The dongle couples with a USB connector to a USB port of the peripheral display with one ground pin of the port and connector having opposing pull-up and pull-down resistors so that a high signal at the ground pin selects a mux to communicate text data and a low signal selects the mux to communicate USB data. The text data includes UART text strings with flexibility to use I2C communications for firmware updates and other data and command transfer applications.

Dependent claims

An information handling system comprising:

a housing;
a processor coupled in the housing and operable to execute instructions to process information;
a memory coupled in the housing and interfaced with the processor, the memory operable to store the instructions and information;
a peripheral display separate from the housing and interfaced with the processor, the peripheral display operable to present the information as visual images, the peripheral display having an interface board with a scalar, a non-transitory memory and plural ports interfaced with the scalar including at least one USB port having a first configuration that communicates USB-formatted information and a second configuration that communicates text-formatted information;
a dongle having a USB port connector operable to couple to the at least one USB port, a text-to-speech audio processing resource operable to translate text-formatted information to audio and a speaker operable to play the audio;
and
instructions stored in the non-transitory memory that when executed on the scalar cause:
identification of the dongle when the dongle connector couples to the at least one USB port;
and
communication of display operation instructions as text-formatted information played as audio by the text-to-speech audio processing resource.
