- ItemMetadata onlyBancada: Using Mobile Zoomable Lenses for Geospatial Exploration(ACM, 2014) Rodrigues, Francisco Marinho; Seyed, Teddy; Maurer, Frank; Carpendale, SheelaghNowadays, looking at the path between two points on a city map has become a simple task using any modern tablet, smartphone or laptop. However, when exploring maps with different information across multiple layers and scales, users experience information discontinuity. Bancada is a multi-display system developed to investigate the exploration of geospatial information using multiple mobile devices in a multi-display environment. In Bancada, tablets are Zoomable Magic Lenses that augment, through specific geospatial layers, an overview map displayed on a tabletop or on a wall display. Users interact with lenses using touch gestures to pan and zoom; and multi-layer maps can be built by overlapping different lenses. Currently, Bancada is being used to research user interfaces separated across multiple devices and interactions with high-resolution mobile devices. Future work with Bancada includes (i) evaluating the user performance when using one tablet or multiple tablets to control all lenses; (ii) exploring what and how interactions can be performed on an overview map; and (iii) exploring how lenses can be changed.
- ItemMetadata onlyExploring 3D volumetric medical data using mobile devices(IEEE, 2014) Seyed, Teddy; Rodrigues, Francisco Marinho; Maurer, Frank; Tang, AnthonyMedical imaging specialists have traditionally used keyboard and mouse based techniques and interfaces for examining both 2D and 3D medical images, but with newer imaging technologies resulting in significantly larger volumes of 3D medical images, these techniques that have become increasingly cumbersome for imaging specialists. To replace traditional techniques, using mobile devices present an effective means for navigating and exploring complex 3D medical data sets, as they provide increased fluidity and flexibility, leveraging people's existing skills with tangible objects. 3D interactions using mobile devices may provide benefit for imaging specialists, but little is known about using these interactions in the medical imaging domain. In this paper, we explore the design of 3D interaction techniques using mobile devices and preliminary feedback from imaging specialists suggests that these interactions may be a viable solution for the medical imaging domain.
