How the hypertext is changing our relation with the information
The next examples provide different experiences were the user experience was enhanced by different ways of connecting the text itself with other relevant publications. It gives the notion of the hypermedia itself taken to different contextâsuch as web pages, image browsing, books, readings, among others. It is crucial to understand the user mental model and how it interacts with the information displayed to choose the appropriate representation and connection among the information displayed and other media resources. It is also important to figure out how the information is displays, as it is discussed here, different kinds of knowledge need different kinds of representationâalways depending on whom is interacting with the information.
Hypertext denotes text composed of blocks of text, and the electronic links that join them. Hypermedia extends the notion of the text in the hypertext by including visual information, sound, animation and other forms of data. This concepts evolve the concept of reading and learning by making possible new ways of interacting with the contents. Reading intermedia versions of the text could make it much more customizable thus improving the connection between the reader and the content.
It is relevant to understand this concept in order to design categorization schemas that improve the user experience given the human brain does not think about memorizing categorization but association. The author, Bush, proposes the creation of memex, An interactive device closer to human behavior than the devices currently available. The important thing about memex is its capability of associative indexing.
There are three toes of linking content or lexias, as bush determines i: unidirectional, bidirectional, or string to lexia. The last one encourages different kinds of annotations and linking, and it allows to indicate different kind of link destinations. There are three types of linking the string to alexia, it could be: string to string, many to one string and string to many. This last one is particularly handily for creating glossary functions, as we can see in text editors such word.
Particularly in the WWW we can find other types of linking, all of them are important in their context, and the crucial part is to know when the context allows us to use them. Electronic linking shifts the boundaries between the text, the author and the reader.
How we interact: Literary machines
The idea of create different pathways for different readers, based upon background taste and understanding. There are different ways to connect the texts: based on non sequential patternsâdifferent types of knowledge as its seen in magazines or newspapersâ, based on chunksâmaterial is important combined with othersâand the windowing or compounding textânon sequential text leads to other stored materialâ.
It is important to understand what representation of the structures and ideas the author wants, because the writing is non but the representation of whole structures of ideas, and placing of them on the page for others to understand, also known as writing. Computers are not involved with this concepts that lead us to hypertext, but will be in every way, and system of every style.
How we think: Sensemaking
Searching for representation and encoding data in that representation to answer task specific questions. Representation chosen changes the cost of the operations in information processing tasks. Thus changing methods or representations con produce payoffs.
How we understand: Faceted Metadata
An introduction to an alternative representation of images based on enabling users to navigate along conceptual dimensions that describe the images. The interface makes use of hierarchical faceted metadata and dynamically generated query previews. A usability study, in which 32 art history students explored a collection of 35,000 fine arts images, compares this approach to a standard image search interface. A category-based approach is a successful way to provide access to image collections.
Thus image access interface allows users to navigate a large collection using hierarchical faceted metadata in a flexible manner. Despite the fact that the interface was often an order of magnitude slower than a standard baseline, it was strongly preferred by most study participants. These results indicate that a category-based approach is a successful way to provide access to image collections.
These different examples of hypertext representation gives us an impression of the importance of the context when representing different types and kind of information. It is proven on these texts that the nature of the information itself will fit different types of interaction given the user experience and the user interaction with the information. Depending on the purpose of the study one or another way of representing the information could be more useful, thus for images the study of the semantic description provided a better brewing method, compared to the memex example that gives the reader a different way of reading and interact with the text. These examples should be considered when defining the affordance of the information system we create, as we want to improve the user experience by making its interaction with the computer simpler and easier.
