I'm developing a survey on usability, I don't think it's quite right yet, but I would still welcome anyone using it to leave feedback on my research topic (or about the survey) - Click Here to take part in a usability survey, and support my PhD research, for anyone who does not want to remain anonymous, I would be pleased to take an interest in their research.
The survey compares these interfaces -
Taxonomy - http://www.cems.uwe.ac.uk/~phale/ELearning/ELearningDemonstration1.htm.
Diagrammatic - http://www.cems.uwe.ac.uk/~phale/ELearning/ELearningDemonstration2.htm.
And asks for further advice on end-user programming.
I'm interested in feedback from anyone, whatever their level of IT skills.
The aim is to make it possible to provide a high level interface to software that represents a problem in a way that is meaningful to users, and that allows them to make changes to the representation and understand the impact of those changes.
SVG (Scalable Vector Graphics), Ontology and Decision Support system re-implementation of my early research into providing interactive manipulation and costing of components - Later SVG research - using open architecture.
The earliest research was into providing a user driven model development example that would provide the kind of user interface and visualisation required for interactive costing. The prototype demonstrates how wing design could be aided by modelling visually and interactively with feedback provided immediately. As the inputs changed, calculations and the diagrammatic visualisation changed in response. This was provided as a visual basic executable and so is a low cost option compared to using a full CAD system. The Figures show this.
The Visual Basic implementation works well for making certain wing design decisions, but information and software is locked into this specific system and for this problem. For this to be re-implemented for a different problem or using different software languages more work is required. So the next stage in the research was to investigate information representation languages that could be adapted and re-used for different problems, particularly for representation of information and calculations in a generic way - this is explained here - http://www.cems.uwe.ac.uk/~phale/.
The flexibility of information representation languages could enable administrative users to maintain, adapt and extend a system themselves. The users can interact with XML via programs written in interpreted languages such as JavaScript, this is examined here - http://www.cems.uwe.ac.uk/amrc/seeds/Ajax/ajax.htm. This approach does not require the user to install software as this works within a browser. The advantage of an interpreted language is that code can be created on the fly. It is then possible for simple code to be written which follows rules in order to generate more complex code, which can then run. If a higher level visual interface is added which can communicate the wishes of users, it then becomes possible for user-driven programming. Software then acts with the user in a way that seems 'intelligent' and responsive, instead of commissioning for software development, the user can communicate with a visual interface, and this translates to controlling code, which writes temporary code to achieve what the user wants. This is little more difficult than the current techniques for allowing code to generate documents, database tables, and XML on the fly.
