Title: Introducing Design Principles
Author: Moothia Vaylen

The following is the coursework about Introducing Design Principles. It is mainly about search engine where we need to time some users doing research on certain search engine. It is some kind of group work for the research but the report is a personal for each student. The report follows. Introduction

Search engine is a software use to search information on the web. It is displayed as a webpage format. The user only needs to insert the searching data and click on search. The search engine will go and fetch corresponding sites in an indexed database and display then according to their relevance. Novice users have been selected to test and rate certain search engine. The following report will display the methods and result about how the research was conducted. Methods

The class was divided in to two groups, each of 2 students. The first group will do their research activity on Web browsers and the second group (mine), we will conduct the research for the Search Engine. Firstly my partner and I, we selected 6 search engines which we will use for the study. The search engines are:1. Google 2. Yahoo

3. AOL
4. Yandex
5. Lycos
6. Duckduckgo
The six search engine was classified randomly in to two groups of 3. We choose a web browser to drive the experiment. It is Mozilla Firefox. The User for our groups needs to choose a concept which will be search on the search engine. Each search was timed and recorded in a table. The user gave the good points and bad points for the design principles according to their search. The same experiment was repeated with other participants for the second group. The users had to rate each search engine of the second group on a scale of 1 to 10. At the end we had to give what are the best design principles for a search engine.

Focus of Study: Search Engines
Web browser used: Mozilla Firefox

First Group

Time is given in second.

Search Engines| User 1| User 2| User 3| User 4| User 5|| 4| 5| 3| 4| 4|| 3| 3.5| 4| 4| 4|| 4| 4| 6| 4| 3|

Design Principle for Group 1:
1. Functionality
* Relevance: On searching, it output pertinent and precise data to the user. The links are sorted according to their relevance. * There is a “Did you mean” function. This gives the user another possible search of the search engine detects a typing error in the searching item. * There are too much other links on the home page. It is difficult for a new user to locate where to make the search. 2. Usability

* Auto Suggestions; it is a help that is provided to the user. It gives of possible words that the user is searching. Then instead of typing completely the user can just click on the word (group of word) to search. * An advance search is available for users that need more specific research. 3. Accessibility

* Help page is available for anyone who do not understand how to make a search or getting any difficulty * It can be access on a mobile phone or any devices which has an internet connection. * There are different sites for different country. Thus in different style and languages. 4. Acceptability

* Different languages are available. People can change it to a language which they can understand it better * There is a parental filter which enables parents to know what their children are searching.

Second Group
Time is given in second.

Search Engines| User 1| User 2| User 3| User 4| User 5| Google| 1| 1| 1| 1| 1|
DuckDuckgo| 3| 3| 4| 2| 2|
Yandex| 3| 5| 8| 4| 6|

Rating of User (Range 1- 10)
Rating| User 1| User 2| User 3| User 4| User 5|
Google| 10| 9| 9| 8| 9|
DuckDuckGo| 9| 7| 7| 7| 8|
Yandex| 9| 8| 7| 8| 8|

Design Principle for Group 2:
1. Functionality
* The speed for search is relatively high compared to the group...
