Digital Scoring system

I need an electronic scoring system which could be used wherever up to five panelists are required to confidentially evaluate an item or event and display their findings simultaneously for the benefit of a scorekeeper and an audience. The system should ultilize a computer which will have up to five usb numberic keypad connected. The computer will capture and controls the voting while the monitor displays the individual votes and total score.? ? Results are also saved in an Excel or text file or MySQL database file for recordkeeping.? As an image is projected, each judge selects a number on his individual control.? After the last vote, regardless of order, the individual votes and the average score will be automatically displayed in large characters on the computer monitor.? After the score is recorded, pressing the computer space bar will reset the system for the next vote. Currently I already have a scoring system which is via manual entry, if this new system could sit on the current system, it would be good. ## Deliverables If every entry could be tag with a bar code, it would be preferred.
