Executive Summary

There is a growing specialization in terms of information technology resulting to a strong tendency in meeting consumers needs. Web design should therefore be intended for the development of an organization. The process of web design may utilize multiple disciplines such as animation, authoring, human computer interaction, graphic design and even interaction designed, all aiming at meeting a given objective. The following research will focus on an effective system that employs the star model framework (Lowgren et al 2004). The concept is the foundation upon which various organizations base their design choices. The following study aims at presenting an evaluation on how effective is the star model in designing an effective website.

Introduction

Human Computer Interaction (HCI) is characterized by the way people interact with computers and to an extent, how we can understand computers. This type of interaction can be divided into there parts which include the user, computer and the way through which they interact. The main goal of HCI is to produce usable, functional as well as a safe system. The study presents the concept of understanding the factors which determine how users entertain technology (Stapleton 1997). The other segment involves the development of tools and techniques that give rise to an effective suitable system. There are several factors that ought to be considered when analyzing and designing a Website using the HCI principles.

There are three categories of interaction design concepts which are the star model, the dynamic systems development method (DSDM) and the user centered lifecycle design model. The star model interaction design will be used to create an effective web site that takes into account the needs. Human Interaction Design aims at understanding technology in a better way and hence helps in avoiding problems that result thereafter. It is therefore imperative that in observing the star mode, we employ the concept of usability. Application of this design should therefore aim to strive for consistency as well as enabling frequent users to take shortcuts in accessing information from the site (Plumley 2010). The following study offers a better solution as to why website development employs the star model

Development Methods

In order to positively evaluate interaction design, the system ought to develop a meaningful relationship between the service and people. Human Computer Interaction must therefore be related to methodologies and processes for designing interfaces. For instance, it will be important to develop the best possible interface within given constraints (Costabile et al 2005). It will also be composed of techniques geared towards implementing interfaces.

Interaction design aims at defining as well as facilitating an interaction between human beings through the service being provided[1]. Furthermore, a good design should involve human interaction as pertaining people, objects and spaces. It goes without mentioning that interaction design basically focuses on the human behavior (Ratner 2003). It should also be noted that interaction design is characterized by the evolution of art, architecture as well as media studies.

On the other hand, we can assert that several models and theoretical approaches have been used so as to help users understand technology. Interaction design entails several disciplines that include the user experience design which is envisioned by information architecture, communication design, and user interface engineering and human factors (Saffer 2009). It also involves industrial design as well as human computer interaction. The concepts involve unique processes that all are all aiming at usability status.

(Stapleton 1997)

The Star Model Concept

In this type on Human Computer Interaction, we look unto some steps that include task analysis verses functional analysis, requirements verses specification, conceptual design verses formal design representation, prototyping and the implementation phase.

Task analysis/functional analysis

The consumer’s needs are what are taken into consideration in developing a website. It is therefore imperative to consider what users are advocating for while visiting a given website and incorporate their views. The system will be characterized by interviews, survey and analysis with an aim of making an effective system and interactive usability status.

Requirements/specification

In developing a website, there are some requirements that have to be taken into consideration. It will be of necessity to tackle the characteristics of a website, the general outlook, site navigation and the several dynamic parts that involve websites.

Conceptual design/formal design representation

This is the most fundamental phase in any development of a website. This phase of the star model describes involves the user interface as well as the overall system and operational design. This is the focal point within which further development into a website arises (Lowgren et al 2004). It takes into consideration the use of splice tools meant for designing and development of the site.

Prototyping

The named phase is fundamental in the evaluation of a given website using the star model. Furthermore, it involves the development of a prototype in regard to the system with an aim of assessing the vital requirements and their functionality.

Implementation

This is the phase that illustrates how the website is being used. This phase enables developers to evaluate how vital the various stages can be. The system can now employ various segments into bringing out the needs of consumers.

  1. Effective Web Design

In this stage, the research comes up with the steps that are taken so as to develop the web design. Consequently, the phase involves bringing into account the various aspects that were collected earlier pertaining usage of the website (Plumley 2010). We can be able to evaluate an effective web site if it has followed the required guidelines and rules with regard to accessibility. The following points can well demonstrate how the website should aim for.

  • It should strive for consistency: Consistency ensures that users are able to use the site without being subjected to difficulties.
  • Users should be able to use short cuts: The user can be able to handle the system appropriately by using the site.
  • There is provision for informative feedback: Such type of website offers n opportunity for disgruntled users to state the areas that need improvements.
  • Option of designing dialogs to yield closure: The website employed an interaction mechanism that offered users an opportunity of simplicity.
  • The website should allow for easier reversal of the action that have been undertaken, and which may result to negative impact in the organization.
  • Error Prevention: In designing the website, the study took into consideration the importance of allowing an easier way to handle errors that might arise.
  • Supporting the internal focus of control is the other aspect that the website aims at achieving.
  • Provision of an easier way of using the system by reducing short term memory load. Reduction of the load enables easier retrieval of information from the system.

3.1 Incorporating Accessibility, Usability and Portability in Web Design

  • Usability: The design format of the website has employed the guidelines regarding usability so as to meet the needs of consumers.
  • Website portability: The concept involved in this case has been the use of HTML language which offers website portability.
  • Accessibility: The developed website can easily be accessed with consumers who are in need of particular information.
  1. Information Architecture

Information architecture comprises of the structural details of the information involved. In order to present an idea on how the content is compounded, the study describes the fundamental steps followed so as to achieve a perfect website. The information carried on eth website is fundamental in arriving at ones objective (Ratner 2003). On the other hand, lack of meeting users need goes against the laws described in website regulations.

In this section, there will be analysis and design of the data stored by the website where by there is concentration on entities, their attributes as well as interrelationships. The information in web development therefore entails modeling of data in regard to individual data base for the users in a site. The website will focus on bringing principles of designs as well as architecture to the overall view with employing the aspects of effective web design.
