device through recognition of hand drawn markings. More
particularly, the hand drawn marks are rendered in electronic
form by the use of a video camera and the electronic
representation of the marks is analyzed to identify two types
of hand drawn marks; a command designator, indicating a
particular type of function or operation to be performed, and
a selection designator, the detection of which causes the
function of operation to be performed.
Representative independent claim 1 is reproduced as
follows:
1. A method of initiating an action of a computing
device using a hand drawn command designator hand drawn on a
surface that produces no output in electronic form, an
electronic camera system capturing an image of a set of hand
drawn marks on the surface to generate an electronic rendition
of the surface, the set of hand drawn marks including the
command designator, a selection designator and other hand
drawn marks, the method comprising:
a) analyzing the set of hand drawn marks represented by
the electronic rendition of the surface to recognize the hand
drawn command designator;
b) analyzing the set of hand drawn marks represented by
the electronic rendition of the surface to recognize the
presence on the surface of the hand drawn selection
designator, the presence of the selection designator
indicating selection of the action associated with the command
designator; and
c) initiating performance of the action by the computing
