Following the positive feedback and the large audience of the first two editions of the HDI workshop in Kyoto (Japan) 2017 and Sydney (Australia) 2019, the Third Int. Workshop on Human-Document Interaction (HDI 2021) will focus on how humans interact with written information around them, and the interfaces between users and documents. The term document is meant here in the wider possible sense, to refer to any physical object that carries static or dynamic written information. The workshop aims to create a space for debate between the Document Image Analysis and Recognition and the Human-Computer Interaction communities. We consider that initiating this dialogue is relevant and timely.

Scope and motivation

Visual processing and association is an important capacity in human communication and intellectual behavior. Visual information addresses patterns of understanding as well as spatial assemblies. This also holds for office environments where specialists are seeking for best possible information assistance for improved processes and decision making. In the mean time, physical and digital documents are settling to coexist in peace - connecting the two is empowering for both sides. Technology advances, such as in augmented reality, permit bringing forms of digital interaction to the physical world and vice versa, while the linking between the physical and the digital world is done in an increasingly more fluid and realistic manner. A new generation of readers, conditioned by the affordances offered by electronic content and the new media types (e.g. blogs and social media posts), have developed distinct reading behaviours and new ways to interact with written content. Wearable sensors allow observing the user and introducing the user context it in the loop, offering personalised services by intelligently linking written information with the user actions. Internet of things is evolving the way everyday objects (many of them carriers of text) can influence our actions.
