- ItemOpen AccessDesigning Camera Controls for Map Environments(2019-01-16) Danyluk, Kurtis; Willett, Wesley J.; Willett, Wesley J.; Sharlin, Ehud; Samavati, FaramarzWe present an exploration of two classes of navigation techniques designed for representations of real-world terrain. The first introduces look-from camera controls, a new style of camera control for touch devices designed with representations of real world-terrain in mind and provides an evaluation of three different implementations of this style of control. The second looks to virtual reality and compares the effectiveness of four existing and common camera control techniques within the context of a representations of real world-terrain. Effective camera controls greatly increase a user’s ability to engage with a virtual environment, and virtual map environments are no different. However, current camera controls are difficult to use within map-like environments, requiring burdensome sequences of interactions or performing poorly within ragged terrain. To examine the effectiveness of different camera controls in this space we conducted two studies in which we asked participants to perform map reading and interaction tasks. In both studies the camera control technique greatly influenced participant engagement and enjoyment within a scene. The first study highlights the effectiveness of look-from camera controls as light-weight additions to direct manipulation controls and provides design guidelines for the construction of look-from camera controls. The second study highlights which existing common navigation techniques are most appropriate within a map-like environment presented in immersive virtual reality and how combinations of these controls can combine the strengths of the controls to cover for the weaknesses of others.
- ItemOpen AccessEvaluating the Performance of Virtual Reality Navigation Techniques for Large Environments(Springer Nature Switzerland, 2019-01) Danyluk, Kurtis; Willett, WesleyWe present results from two studies comparing the performance of four different navigation techniques (flight, teleportation, world-in-miniature, and 3D cone-drag) and their combinations in large virtual reality map environments. While prior work has individually examined each of these techniques in other settings, our study presents the first direct comparison between them in large open environments, as well as one of the first comparisons in the context of current-generation virtual reality hardware. Our first study compared common techniques (flight, teleportation, and world-in-miniature) for search and navigation tasks. A follow-up study compared these techniques against 3D cone drag, a direct-manipulation navigation technique used in contemporary tools like Google Earth VR. Our results show the strength of flight as a stand-alone navigation technique, but also highlight five specific ways in which viewers can combine teleportation, world-in-miniature, and 3D cone drag with flight, drawing on the relative strengths of each technique to compensate for the weaknesses of others.
- ItemOpen AccessOne Week in the Future: Previs Design Futuring for HCI Research(ACM, 2022-03-10) Ivanov, Alexander; Au Yeung, Tim; Blair, Kathryn; Danyluk, Kurtis; Freeman, Georgina; Friedel, Marcus; Hull, Carmen; Hung, Michael; Pratte, Sydney; Willett, WesleyWe explore the use of cinematic “pre-visualization” (previs) techniques as a rapid ideation and design futuring method for human computer interaction (HCI) research. Previs approaches, which are widely used in animation and film production, use digital design tools to create medium-fidelity videos that capture richer interaction, motion, and context than sketches or static illustrations. When used as a design futuring method, previs can facilitate rapid, iterative discussions that reveal tensions, challenges, and opportunities for new research. We performed eight one-week design futuring sprints, in which individual HCI researchers collaborated with a lead designer to produce concept sketches, storyboards, and videos that examined future applications of their research. From these experiences, we identify recurring themes and challenges and present a One Week Futuring Workbook that other researchers can use to guide their own futuring sprints. We also highlight how variations of our approach could support other speculative design practices.
- ItemOpen AccessUnderstanding Gesture and Microgesture Inputs for Augmented Reality Maps(2024-07-01) Danyluk, Kurtis; Klueber, Simon; Nittala, Aditya Shekhar; Willett, WesleyWe explore the potential for subtle on-hand gesture and microgesture interactions for map navigation with augmented reality (AR) devices. We describe a design exercise and follow-up elicitation study in which we identified on-hand gestures for cartographic interaction primitives. Microgestures and on-hand interactions are a promising space for AR map navigation as they offers always-available, tactile, and memorable spaces for interaction. Our findings show a clear set of microgesture interaction patterns that are well suited for supporting map navigation and manipulation. In particular, we highlight how the properties of various microgestures align with particular cartographic interaction tasks. We also describe our experience creating an exploratory proof-of-concept AR map prototype which helped us identify new opportunities and practical challenges for microgesture control. Finally, we discuss how future AR map systems could benefit from on-hand and microgesture input schemes.
