Handwritten text capture via interface surface having coded marks

A system for enabling user interaction with computer software running in a computer system via:

• an interface surface containing information relating to the computer software and including coded data indicative of a text field, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions;
• and
• a sensing device which, when placed in an operative position relative to the interface surface:
• senses at least some of the coded data,
• generates indicating data indicative of the text field, and
• generates at least one of movement data and position data, the movement data being indicative of the sensing device's movement relative to the interface surface, the position data being indicative of the sensing device's position relative to the interface surface;
• the computer system being configured to:
• (a) receive the indicating data from the sensing device;
• (b) receive at least one of the movement data and the position data from the sensing device;
• (c) identify the text field from the indicating data;
• and
• (d) operate the computer software at least partly in reliance on at least one of the movement data and the position data, and in accordance with instructions associated with the text field.

A system for enabling user interaction with computer software running in a computer system, the system including:

• an interface surface containing information relating to the computer software and including coded data indicative of a text field relating to the computer software, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions;
• the system being configured to, in the computer system:
• (a) receive indicating data from a sensing device, the indicating data being indicative of the text field, wherein the sensing device, when placed in an operative position relative to the interface surface:
• senses at least some of the coded data,
• generates the indicating data, and
• generates at least one of movement data and position data, the movement data being indicative of the sensing device's movement relative to the interface surface, the position data being indicative of the sensing device's position relative to the interface surface;
• (b) receive at least one of the movement data and the position data from the sensing device;
• (c) identify the text field on the basis of the indicating data;
• and
• (d) operate the computer software at least partly in reliance on at least one of the movement data and the position data, and in accordance with instructions associated with the text field.
