This page contains additional resources on distance-dependent barcodes as a companion for the following research article:
Distance-dependent barcodes provide users with different data based on their scanning distance. These barcodes employ color blending as the key technique to achieve distance-dependence and can be used to realize context-aware mobile application. The following video overviews distance-aware barcodes in the context of casual interactions with public displays.
The released software includes a sample Android application that is able to scan distance-aware barcodes.
