Abstract:
A touch ahead capable touch screen system comprising:a data processing system for receiving and processing data items, the data processing system being also operative to generate graphic images for providing information to an operator and facilitating data entry by the operator, the data processing system being further operative to generate updates to the graphic images depending on the data items received; a display for displaying the graphic images, one or more of the graphic images being adapted to direct entry of one or more of the data items by an operator, entry of each data item being accomplished by one or more touches to the graphic images; a touch detector for detecting an occurrence and location of each of the touches, the location of each touch being translated to reflect one of the data items, the touch detector being operative to transmit each data item to an appropriate destination; and a buffer adapted to receive each data item from the touch detector and transmit it to the data processing system, the buffer being able to receive each data item in a sequence of one or more data items, each data item being created by the touch detector as a result of detection by the touch detector of a sequence of touches comprising one or more touches and translation by the touch detector of the sequence of touches into the data item, the buffer being able to receive data items from the touch detector without a need to wait until the display has been updated before receiving the data items, the buffer being adapted to hold each data item until the data processing system is ready to process it, the buffer being operative to hold each data item until the display has received and processed updated graphic images delivered as a result of preceding data items resulting from detection of touches by the touch detector.
