Please respond to the following:

“Interface Design Models” Please respond to the following:

• Evaluate interface design models and describe design issues across human-computer interaction environments associated with these models. Support your response.

• Building an interface can be broken down into the phases of design and development. Analyze the activities that take place in both phases, and explain why certain activities should be included in design but not in development.

NJ’s post states the following:

“Interface Design Models” Please respond to the following:

Evaluate interface design models and describe design issues across human-computer interaction environments associated with these models. Support your response.

The Design process includes several phases to helps established design requirements specification, preliminary details, built implementation, and evaluation of the end products. HCI must be incorporated related to usability requirements at each and every expectation of the design process phases. The HCI design approach comes with process issues as follows:

1. Who interact directly with the product to achieve the task 

2. Who manage direct users 

3. Who receives output from the product 

4. Who makes the purchasing decision 

5. Who use competitor’s products 

Human-Computer Interaction (HCI) is about humans interacting with computers that determine the requirements interface between humans and computers is crucial to facilitate this interaction. HCI is a multidisciplinary field of study focusing on the design of computer technology and user software for desktop applications, internet browsers, handheld computers, ERP, and computer kiosks, and prevalent graphical user interfaces (GUI). In general, the HCI essential concept will make systems easy to learn, easy to use, and with limiting error frequency and severity, and achieve efficiency, effective, and safe interaction between human and computer interfaces and interactions.

Building an interface can be broken down into the phases of design and development. Analyze the activities that take place in both phases, and explain why certain activities should be included in design but not in development.

The Design model involves several Phase stages in an iterative and cyclical process that feedback with cross-cutting factors which included academic and user requirements to achieve a quality product, as follows: 

Phase 1: Requirement analysis is critical to the success or failure of a systems or software project which should be documented, actionable, measurable, testable, traceable, related to identified business needs or opportunities, and defined to a level of detail sufficient for system design.

Note: This should not be included in development process, it only establish the design requirement

Phase 2: Preliminary and detailed design is a high-level design approach to bridging a gap between design conception and detailed design that establishes the overall system design configuration, schematics, diagrams, and layouts of the project requirements and standards. During detailed design and optimization focused on parameters of the part may change and create a general framework for built completion.

Phase 3: Built and Implementation is the initial development of the prototype design to establish the configuration based on the initial design requirements and specifications to implement a preliminary product model. To evaluate the prototype product design for proof of design and usability HCI requirements. 

Phase 4: Evaluation process is to determine proof of product design will include tests of functionality, operability, usability, and user HCI requirements in an overall structured approach to determine the quality and effectiveness of the design. Also to validate the product to conform to test performance and implementation requirements in accordance with established design requirements.
