Method and system for online purchasing using coded marks
First Claim
Patent Images
1. A method of enabling online purchasing via a printed form, said method comprising the steps of:
- providing the printed form containing information relating to a purchasing transaction and coded data printed as a collection of tags, each tag identifying an identity of the form and the position of the tag on the form form, the coded data comprising a plurality of undifferentiated marks positioned relative to a set of predetermined nominal mark positions,operatively positioning an optically imaging pen relative to the form, said pen having a nib;
sensing a tag on the form;
computing the position of the nib from an observed perspective distortion on the sensed tag and a known spatial relationship between the pen'"'"'s physical axis and the pen'"'"'s optical axis, said axes being different from each other;
transmitting, to a computer system, indicating data from the pen, said indicating data being indicative of the identity of the form and a position of the nib relative to the form;
thereby enabling the computer system to;
identify at least one parameter relating to the purchasing transaction using the indicating data; and
initiate the online purchasing using the at least one parameter identified.

Abstract
Methods and systems are disclosed which relate to online purchasing via interface surfaces printed with information and coded data. The coded data, encoded visibly or invisibly, may be queried by an appropriate sensing device. The sensing device communicates with a computer system. Together, the interface surfaces, sensing device and computer system are capable of effecting purchasing transactions over a network.

26. A system for enabling online purchasing via a printed form, said system comprising:
-
a printed form containing information relating to a purchasing transaction and coded data printed as a collection of tags, each tag identifying an identity of the form and a position of the tag on the form, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions; an optically imaging pen having a nib, said pen being configured for; sensing a tag on the surface; computing the position of the nib from an observed perspective distortion on the sensed tag and a known spatial relationship between the pen'"'"'s physical axis and the pens'"'"'s optical axis, said axes being different from each other; transmitting, to a computer system, indicating data indicative of the identity of the form and the position of the nib on the form; and a computer system configured for; receiving the indicating data from the pen; identifying at least one parameter relating to the purchasing transaction using the indicating data; and initiating the online purchasing using the at least one parameter identified. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
