Interaction Design

2007-04-10T21:35:26Z

200.238.102.162:

{{Quotation|The design of how a user communicates, or interacts, with a computer. Interaction designers focus on the flow of interaction, the dialog between person and computer, how input relates to output, stimulus-response compatibility, and feedback mechanisms. This is in contrast to a visual designer, who may be trained in designing visualizations for static media but not necessarily in the dialog which is present in all interactive media. A “visual interaction designer” is a visual designer with interaction design skills. Interaction design is also in contrast to information architecture - an information architect looks at the organization of information to make the structure of a complex system easy to conceptualize and navigate, but is not usually focused, for instance, on low-level interactions. For example, an information architect may design the structure of an entire website, but not have as much interest in the design of individual pages and how users interact with forms and other controls. |[Usability First, 2003]}}

2006-03-20: Webcast by Ben Shneiderman on Information Exploration

2007-04-10T20:28:26Z

200.238.102.162:

[[Shneiderman, Ben|Ben Shneiderman]] presents a one hour webcast on: 
'''The Thrill of Discovery - Accelerating Information Exploration'''

*Wednesday, March 29, 2006 - 11:00 am, Eastern Standard Time (GMT -05:00, New York)
*Wednesday, March 29, 2006 - 6:00 pm, Europe Daylight Time (GMT 02:00, Paris)
*Wednesday, March 29, 2006 - 8:00 am, Pacific Standard Time (GMT -08:00, San Francisco)

{{Quotation|Exceptional tools for information visualization are becoming more widely used to gain competitive advantages, but the best is yet to come. The next generation of interactive tools will enable communities of users to make successful business decisions even more rapidly. Advances to look for include: 1) systematic strategies for discovery that incorporate the increasingly powerful statistical tools and data mining methods, while accommodating missing and uncertain data. 2) increasingly diverse data types such as time series, patient histories, maps, and social networks, so users can handle a wider array of problems. 3) tighter integration into organizational workflows that amplify individual creativity with the catalytic benefits of social creativity. These ambitious aspirations are already motivating researchers and inspiring developers. This webcast tours current efforts and proposes grand challenges.|[Spotfire, 2006]}}

Visualization Pipeline

{{Definition|The '''visualization pipeline''' describes the (step-wise) process of creating visual representations of data.}}

[[Image:Dossantos04vis pipeline.png|The visualization pipeline describes the process of creating visual representations of data [dos Santos and Brodlie, 2004]]]

#'''Data Analysis:''' data are prepared for visualization (e.g., by applying a smoothing filter, interpolating missing values, or correcting erroneous measurements) -- usually computer-centered, little or no user interaction.
#'''Filtering:''' selection of data portions to be visualized -- usually user-centered.
#'''Mapping:''' focus data are mapped to geometric primitives (e.g., points, lines) and their attributes (e.g., color, position, size); most critical step for achieving [[Expressiveness]] and [[Effectiveness]].
#'''Rendering:''' geometric data are transformed to image data.

'''Description:''' The aim of this project is the development of interactive visualization methods to support protocol-based care.

CareVis provides multiple simultaneous views to cover different aspects of a complex underlying data structure of treatment plans and patient data. The tightly coupled views use visualization methods well-known to domain experts and are designed to facilitate users' tasks. CareVis enables a meaningful navigation, provides annotations on demand for not overwhelming the viewer, and helps to keep orientation by using [[Focus-plus-Context|Focus Context]] techniques, thus increasing the flexibility in working with treatment plans and patient data.
