Apparatus and method for selecting stylus location-determination information provided by a plurality of non-passive stylus-location modalities

摘要

A stylus includes a stylus housing that supports a control circuit. The control circuit is configured automatically compare data quality as corresponds to stylus location-determination information being provided by at least two different stylus-based candidate non-passive location modalities to thereby select a particular stylus-based non-passive location modality and to then use that particular stylus-based non-passive location modality when transmitting stylus location-determination information to a corresponding electronic device.

1. An apparatus comprising:
a stylus configured for interactive use with a surface comprising:
a stylus housing;a control circuit supported by the stylus housing and configured to:
selectively effect at least two different non-passive location modalities such that each of the non-passive location modalities imparts location-determination information; andselect, as a function, at least in part, of a comparison of data quality, whether to transmit the location-determination information from a first one of the at least two different non-passive location modalities or to transmit the location-determination information from a second, different one of the at least two non-passive location modalities.
