“…The subject of IUV with AR is far less frequent-both in the literature and in practical applications-compared to the use of virtual reality. Bucking this trend, Dragicevic [13] approaches AR as a form of 'humanitarian' visualization in which, by relocating a particular event in the user's environment, an emotional and humanitarian connection is fostered with the people behind the numbers. Outside of this specific context, no other examples of the use of AR as a means of visualizing quantitative data have been found within IUV so far.…”

Immersive Unit Visualization is an emergent form of visualization that arose from Immersive Analytics where, unlike traditional visualizations, each data point is represented by an individual visual mark in an immersive virtual environment. This practice has focused almost exclusively on virtual reality, excluding augmented reality (AR). This article develops and tests a prototype of an Immersive Unit Visualization (Floating Companies II) with two AR devices: head-mounted display (HMD) and hand-held display (HHD). Results from the testing sessions with 20 users were analyzed through qualitative research analysis and thematic coding indicating that, while the HHD enabled a first contact with AR visualization on a familiar device, HMD improved the perception of hybrid space by supporting greater stability of virtual content, wider field of view, improved spatial perception, increased sense of immersion, and more realistic simulation, which had an impact on information reading and sense-making. The materialization of abstract quantitative values into concrete reality through its simulation in the real environment and the ludic dimension stand out as important opportunities for this type of visualization. This paper investigates the aspects distinguishing two experiences regarding data visualization in hybrid space, and characterizes ways of seeing information with AR, identifying opportunities to advance information design research.

“…Donation websites such as donorschoose.org or fundraising platforms like gofundme.com act as tools which let users search for similar causes to which allocate their resources, but comparison across these causes is not supported. Prior research has focused on encouraging people to contribute more towards a charity using tools such as conversational agents [65], web interfaces [47,55], and visual media like photographs and visualizations to elicit affective emotions such as compassion [28,40]. These aim to elicit more donations, but little is known about tools to help people allocate available charitable resources more equally.…”

Studies on human decision-making focused on humanitarian aid have found that cognitive biases can hinder the fair allocation of resources. However, few HCI and Information Visualization studies have explored ways to overcome those cognitive biases. This work investigates whether the design of interactive resource allocation tools can help to promote allocation fairness. We specifically study the effect of presentation format (using text or visualization) and a specific framing strategy (showing resources allocated to groups or individuals). In our three crowdsourced experiments, we provided different tool designs to split money between two fictional programs that benefit two distinct communities. Our main finding indicates that individual-framed visualizations and text may be able to curb unfair allocations caused by group-framed designs. This work opens new perspectives that can motivate research on how interactive tools and visualizations can be engineered to combat cognitive biases that lead to inequitable decisions.
