Abstract
Among other things, a holder for an electronic stylus includes a cavity in which the stylus can be placed when not in use. The cavity includes a receptacle at one end for a writing end of the stylus and a stop at the other end. The stop has an opening into which an opposite end of the stylus can be placed. The receptacle has a resilient element to urge the stylus against the stop.

-
21. A method comprising:
-
enabling a user to navigate temporally through a display of handwriting data that is stored in a data file derived from an electronic stylus; and enabling the user to identify a beginning or an end of a segment of handwriting that is to be kept in the file. - View Dependent Claims (22)
-
-
23. A method comprising:
-
enabling users to collaborate by accepting information entered by the users'"'"' handwriting with electronic styli on writing surfaces; and displaying the handwriting of more than one of the users simultaneously in a manner that is visible to the users via at least one receiving device. - View Dependent Claims (24, 25, 26)

-
27. A method comprising:
-
displaying to a user a document to be signed on a device; capturing a signature of the user electronically while the user is signing his/her name on a surface using an electronic stylus; displaying the signature on the document to be signed; enabling the user to move the signature relative to the displayed document until the signature is in a proper location of the document; and enabling the user to send the document with the properly located signature to a remote location. - View Dependent Claims (28, 29)
-
-
30. A method comprising:
-
electronically capturing a signature that a user has written using an electronic stylus; electronically capturing metadata representing characteristics of the signature including pressures applied to the stylus during the writing of the signature; and using the metadata to authenticate a signature that purports to be a signature of the user, based on metadata representing characteristics of the purported signature. - View Dependent Claims (31, 32)
-
-
33. An apparatus comprising:
an electronic stylus that enables electronic capture of data representing a trajectory of the stylus as it is moved across a writing surface, the stylus including a device to detect a level of a force between the stylus and the writing surface as the stylus is moved across the writing surface. - View Dependent Claims (34)
