Abstract
Systems and methods are provided for displaying free-form drawing on a contact-sensitive display. A new contact on the display is detected by a computer. A determination is made by the computer as to whether a width of the new contact is less than a maximum width. When the width of the new contact is less than the maximum width, the width of the new contact is compared to a width of other current contacts by the computer. When the width of the new contact is less than widths of all other current contacts, the new contact is tracked by the computer using a first data structure. A release of the new contact from the display is detected by the computer. Data associated with the new contact is transferred from the first data structure to the second data structure by the computer when the new contact is detected as being released.
