Resumo: Atividades de saúde primária e básica normalmente são realizadas por profissionais que possuem conhecimento generalizado, e o serviço oferecido neste contexto é essencialmente descentralizado. Mesmo com a inserção de tecnologias em saúde, bem como a aceitação do uso de equipamentos móveis, percebe-se que ainda há uma lacuna quanto ao uso desses meios em saúde básica, além de se fazerem necessárias ferramentas de apoio à tomada de decisão baseada nas evidências coletadas. Nesse contexto, este artigo apresenta uma proposta e a experiência de construção de sistema de suporte à decisão móvel de apoio ao diagnóstico médico utilizando árvores de decisão. Palavras-chave:
Emergency response planning is a process that involves many different stakeholders who may communicate concurrently with different channels and exchange different information artefacts. The planning typically occurs in an emergency operations centre (EOC) and involves personnel both in the room and also in the field. The EOC provides an interesting context for examining the use of tablets, tabletops and large wall displays, and their role in facilitating information and communication exchange in an emergency response planning scenario. In collaboration with a military and emergency response simulation software company in Calgary, Alberta, Canada, we developed ePlan MultiSurface, a multi-surface environment for communication and collaboration for emergency response planning exercises. In this paper, we describe the domain, how it informed our prototype, and insights on collaboration, interaction and information dissemination in multi-surface environments for EOCs.
Figure 1. A medical imaging specialist exploring a 3D volumetric image of a human chest using a tablet. Abstract3D volumetric medical images, such as MRIs, are commonly explored and interacted with by medical imaging experts using systems that require keyboard and mouse-based techniques. These techniques have presented challenges for medical imaging specialists: 3D spatial navigation is difficult, in addition to the detailed selection and analysis of 3D medical images being difficult due to depth perception and occlusion issues. In this work, we explore a potential solution to these challenges by using tangible interaction techniques with a mobile device to simplify 3D CHI 2014, One of a CHInd, Toronto, ON, Canada 2341 interactions for medical imaging specialists. We discuss preliminary observations from our design sessions with medical imaging specialists and argue that tangible 3D interactions using mobile devices are viable solution for the medical imaging domain, as well as highlight that domain plays an important role in 3D interaction techniques.
Nowadays, 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.
Medical 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.
