FILTER MODULE TO DIRECT AUDIO FEEDBACK TO A PLURALITY OF TOUCH MONITORS

摘要

Multiple users may interact with the multiple touch monitors simultaneously. For example, a point-of-sale (POS) system may include two touch monitors (e.g., one facing the cashier and another facing the customer) that are controlled by the same operating system. To provide audio feedback to both users, the operating system needs to know on which monitor the touch event occurred. However, because the operating system may use a shared coordinate region, it only knows that a touch event occurred within the region but not know on which monitor. As such, embodiments herein describe a filter module that identifies a specific location of a touch event within the shared coordinate region and maps that location to one of the touch monitors. Once the specific touch monitor is identified, the filter module sends an instruction that causes a speaker assigned to the identified touch monitor to output the audio feedback.

主权项

1. A method for providing audio feedback for a first touch-sensitive display and a second touch-sensitive display, the method comprising:
receiving touch data from one of the first and second displays, the touch data indicating that a touch event occurred on one of a first integrated touch/display area in the first display and a second integrated touch/display area of the second display, wherein the first and second displays are housed in separate physical enclosures; identifying a location of the touch event in a shared coordinate region that extends across both the first touch/display area and the second touch/display area; selecting one of the first and second displays by correlating the location of the touch event to a sub-portion of the shared coordinate region corresponding to one of the first and second touch/display areas; and transmitting a signal to a speaker assigned to the selected display, the signal causing the speaker to output audio feedback associated with the touch event.
