High-Performance Pen + Touch Modality Interactions: A Real-Time Strategy Game eSports Context

摘要

We used the situated context of real-time strategy (RTS) games to address the design and evaluation of new pen + touch interaction techniques. RTS play is a popular genre of Electronic Sports (eSports). games played and spectated at an extremely high level. Interaction techniques are critical for eS-ports players, because they so directly impact performance. Through this process, new techniques and implications for pen + touch and bi-manual interaction emerged. We enhance non-dominant hand (NDH) interaction with edge-constrained affordances, anchored to physical features of interactive surfaces, effectively increasing target width. We develop bi-manual overloading, an approach to reduce the total number of occurrences of NDH retargeting. The novel isosceles lasso select technique facilitates selection of complex object subsets. Pen-in-hand interaction, dominant hand touch interaction performed with the pen stowed in the palm, also emerged as an efficient and expressive interaction paradigm.
