Abstract The
assignment will start with an overview over different
discrete
interaction styles, and
will introduce the design of a command language, menu and desktop user
interfaces. The students will apply this design knowledge on a new design of a
not yet existing interactive product and come up with a full specification of
the interaction structure, which can be used to build a prototype for user
testing. The first part of this assignment consists of creating a new interactive product idea, design the command language interaction style for the planned functionality with one of a formal specification method from DA301 (or in addition with BNF), and present the specification document/diagram of this command language interface at the second meeting. The second part of this assignment consists of creating a new interactive product idea, design the menu interaction style for the planned functionality with one of a formal specification method from DA301, and present the specification document/diagram of this menu interface at the third meeting. The third part of this assignment consists of creating a new interactive product idea, design the direct manipulation interaction style for the planned functionality with one of a formal specification method from DA301, and present the specification document/diagram of this direct manipulation interface at the fourth meeting. The last part of this assignment consists of implementing one of the three discrete interactions style in a mid-fidelity prototype, and test the result with several users. Based on the recorded users' reactions/comments, recommendations for a possible re-design have to be drawn. The final prototype and the main results of the user tests are presented in the final meeting. Students will learn to design three different interaction styles as input for the implementation of a mid-fidelity prototype. They will gain hands-on experience in (1) using validated design knowledge as input for creating a interactive prototype, and (2) planning and conducting an empirical evaluation. They will experience how to optimise the trade-offs inherent in conducting prototyping and usability testing under 'real-life' constraints. Literature is provided through this web-page (see below). Additional information throughout the assignment will be provided via the assignment emails distribution list DA308 (make sure that your email address is on this list!). |
Assignment
work
The feedback for this assignment will be determined by the work done on the set of deliverables (Dx; see below). Each deliverable (Dx) will cover a number of steps relevant for planning, applying and conducting a combination of formal and empirical methods. Furthermore, they will include discussions about the trade-offs of the decisions taken and the validity of the findings of the evaluation. Feedback will be determined based on the rigour with which the work is done, whether relevant concepts discussed in the assignment are embedded in the work and the report, and extra initiative to ensure good quality of work. |
