Using visuals to convey information
3 likes1,562 views
The document discusses using visualizations to convey information more effectively than text alone. It provides examples of different visualization techniques, such as semantic maps, virtual reality, ubiquitous computing, and 3D interactive visualizations. The author argues that visualizations can improve interfaces by leveraging human perception and more clearly conveying information to support tasks like knowledge sharing and information discovery.

Using visuals to convey information

- 2. Way One: virtual reality
- 3. Way two: ubiquitous computing
- 4. “ Two way” integration: visualisation definition : use of images and animations to convey information goal :effectively convey information to the user transforms the abstract and symbolic into the geometric harnesses the human perception system (visual?)
- 5. Motivation different representations can enhance the understanding level of a particular problem [ Tufte ]. the form of representation makes a dramatic difference in the ease of the task [ Norman ]. Norman proposes that external representations, that can be part of a workspace shared with others, require some sort of constructed device to support them: an artefact. is proposed an interface that tries to remove the computer as an object of perception, allowing the user to interact directly with the generated environment as discussed by [ Hubbold et al ].
- 6. Example one: using old fashion text Semantic Maps strategy for graphically representing concepts, portraying the schematic relations that compose a concept assumes that there are multiple relations between a concept and the knowledge that is associated with the concept for any concept there are at least these types of associations: class: the order of things the concept falls into; property: the attributes that define the concept; example: exemplars of the concept.
- 7. Example two: using real world images Collaboration allows better performance

- 14. One last example: ViDESK prototype (3D interactive visualisation) goals: convey information about a structure for knowledge sharing test how this could support knowledge sharing by proposing a particular system to give support to users in information discovery help users to build their own queries by using a textual search engine based on information from the structure for knowledge sharing allows the visualisation of data source information within the visualisation design and displaying of results using an HTML browser

- 18. Information Visualisation in criteria space
- 20. Concluding remarks use of visualisation techniques can improve the interface by supporting familiar cues to user perception and thus convey information for knowledge sharing people were able to use the several described visualisation designs as the one presented further research need to be conducted in order to adopt visualisation practices within current information current use
