As we know, design is everywhere, but there is question people always asked : What is design?? Design is about making choices and decisions. Physical interface of interactive product should not conflict with the user's cognitive processes invloved in achieving the task. For example, to help avoid memory overload, interface should list options instead of making user remember a long lost of possibilities.
Example : Designing for different culture
On the other hand, lecturer had share about some guidelines to help with international design to us. We have advised to be careful about using images that depict hand gestures or people, such as "thumbs-up", "moutza", "A-OK", and the "Corna". In other way, we can use a generic icon, choose color that are not associated with national flags or political movements. As secure, we have to ensure that the products support different calendars, date formats and time formats, number formats, currencies, weights and measurement systems. Besides, we also have to ensure the size of international paper, envelope sizes and address format. As an information, we have to avoid integrating text in graphics as they cannot be translated easily and allow for text expansion when translated from English.
Using Scenarios in Design
As knowledge, Scenarios can be used to explicate existing work situation but are more commonly used for expressing proposed or imagined situations to help in conceptual design. There are four roles for scenarios:
- A basic for the overall design
- For technical implementation
- As a means of cooperation within design teams
- As a means of cooperation across professional boundaries such as in a multidisciplinary team
Furthermore, scenarios used for the notion of plus and minus scenarios. It attempt to capture the most positive and the most negative consequences of a particular proposed design solution. Besides, it helping designers to gain a more comprehensive view of the proposal.
Using Prototypes in Design
What is Prototype?
"According to Wikipedia, paper prototyping is a widely used method in the user-centred design process, a process that helps developers to create software that meets the user's expectations and needs especially for designing and testing user interface. It is throwaway prototyping and involves creating rough, even hand-sketched, drawings of an interface to use as prototypes, or models, of a design. Other than that, paper prototype is faster and easy to create and it is also easy to change when need any improvement."
For an example: A cell-phone is a good example of prototype. Generating storyboards from scenarios is storyboard represents a sequence of actions or events that the user and the system go through to achieve a task. A scenario is one story about how a product may be used to achieve a task. But how? We have to break the scenario into a series of steps which focus on interaction. Then, create one scene in the storyboard for each every step.
- Generating card-based prototype from use cases
Value of card-based prototype is a screen or screen elements can be manipulated and moved around in order to stimulate interaction. Storyboard which focusing on screen is the card based prototype or can be generate directly from use case output. A prototyping physical design expand the cards to generate a more detailed software or paper-based prototype. There is a tool to support prototyping which is sketching tools, environments to support icon and menu design to widget libraries and so on. The user interface software tools support developers by reducing the amount of code that has be written to implement elements of the user interface such as windows, widgets, and to tie all of them together.
