Abstract: Methods, systems, and techniques for presenting sponsor supplied content associated with commercial opportunities in a gesture-based user interface are provided. Example embodiments provide a Gesture Based Content Presentation System (GBCPS), which enables a gesture-based user interface to determine and present sponsor supplied content associated with an opportunity for commercialization related to a portion of electronic input that has been indicated by a received gesture. In overview, the GBCPS allows a portion (e.g., an area, part, etc.) of electronically presented content to be dynamically indicated by a gesture. The GBCPS examines the indicated portion in conjunction with possibly a set of (e.g., one or more) factors to determine which sponsor supplied content associated with an opportunity for commercialization to present.
