Augmented Reality tutorials, which provide necessary context by directly superimposing visual guidance on the physical referent, represent an effective way of scaffolding complex instrument operations. However, current AR tutorial authoring...

Advanced modeling method for quantifying cumulative subjective fatigue in mid-air interaction

Advanced modeling method for quantifying cumulative subjective fatigue in mid-air interaction

Ana Villanueva, Sujin Jang, Wolfgang Stuerzlinger, Satyajit Ambike, Karthik Ramani
International Journal of Human-Computer Studies 169 (2023): 102931

Interaction in mid-air can be fatiguing. A model-based method to quantify cumulative subjective fatigue for such interaction was recently introduced in HCI research. This model separates muscle units into three states: active (MA) fatigued (MF) or...
