The Age Reading Demostration (ARD) is an interactive application that takes advantage of the graphical interactivity of Adobe Flash. The current version of ARD allows the user to click on the ageing structure image to flag growth rings, zoom and pan the ageing structure image, a scale bar, and compares the user's age with the experienced age reader's age. This page describes features and functionality of the Age Reading Demonstration (ARD) application.
Mouse click: clicking anywhere on the ageing structure image sets a flag and increments the user's age estimate.
Navigation window: the top left corner has a thumbnail image of the ageing structure in a navigation window. The position of the full size image can be changed by dragging the red box inside the navigation window.
Navigation bar: the image position and size is controlled with the navigation bar at the bottom middle of the screen. The bottons include a zoom slider, zoom in and out buttons, pan direction buttons, and an image reset button.
Image Description: This field has pertinent specimen information such as fish length, date of collection, species, and ageing difficulty. Ageing difficulty is a number from 1 to 3, with 1 being easy and 3 being difficult.

The flags can be removed and the ages cleared by pressing the clear all button. A single flag may be removed by clicking the "Clear last" button.
