people are willing to share true identities and build true relationships.

People become addicted to “networks”A common interest or experience promotes

relationship, esp. during first meetings.

Problem SpacePurpose:This product helps people to find friends

within a physical distance according to certain criterion pre-defined by the user, such as hobbies, common friends, experience, etc.

The user becomes a “walking network”.Potential audience People who are interested in finding friends

with common interests or experience.

Problem SpaceCompetitiveness Analysis“real” or bridging the virtual and reality Personalization: Keywords, Profile editing. Matching rate: take advantage of as many

means of connection as possible.

Problem SpaceUse:Public places - Find people who share your experienceFirst meeting - Avoid awkwardness Assumptions:Public context provides indication of people’s

preference, background and so on.People are connectable - “Small world!”People can be generalized and matched by several key

words People have different self-built “identities”, they only

show one facet of themselves(or one identity) in one particular environment.

Conceptual Model (social computing model)

In a concerted effort to design a best-fit application, one that compliments the needs of both the users and the system, the team needs to focus deeply on the key computer mediated components (CMC) required for ultimate acceptance and accomplishment.

Conceptual Model Continued

Key CMC ElementsThe Device will be mobile rather than web-based so

as to not compete with established web applications with similar functionality

Both asynchronous and synchronous communication will be supported.

Users will be able to talk synchronously via Instant Messaging, or text messaging via the typing interface.

Users will conversely be able to communicate asynchronously posting messages while the other users are not currently present.

Conceptual Model Continued

Requirements: Conceptual Requirements:This device will be designed as an application for portable

devices such as smart phones, rather than a web based application.

Connections between people will be based on interest basis rather than a demographic one.

Users will be able to access other users who match them on ideas such as music, hobbies, sports, and other cultural pastimes.

System Requirements:Mobile device with touch-based or PDA type hardware (iPhone,

Blackberry) to facilitate the use of a web-like mobile application.

Conceptual Model Continued

User requirements:ability to read and select choices from a

menu comfortable using a computer and accessing

the internet comfortable with the idea of a support group ability to follow/comprehend a written

conversation (chat) ability to understand written instructions for

use

Product EvaluationFour external evaluators Age : 20 to 32 Three evaluators have IT background

The data we gained from:1. Task Errors2. Post-Task Questionnaire3. Interview

Assessment of Findings(External evaluation)Per four tasks - 2.5 errors (those errors were

mainly happened in performing the task that require participants to set up their interests)

Overall score for post-task questionnaire which focused on the usability of NaviCHAT is 3.86/5

Most participants thought NaviCHAT is useful and easy to use, however, it is also difficult for new users to grab its usage in the beginning

Assessment of Findings (External evaluation)Advanced Information is better to have

standard formThe instruction could be more detailedLocation Profile’s status is better to be shown

on main screenTime-based search could be added inPrivacy issue is be concerned

Assessment of Findings (Internal Walkthrough)Should let users update their status such as

online, away, busy, etc.Friends statuses should be visibleShould let users know the locations where

the other users areShould add page label on every screenButton label should be more clear

Suggested ChangesEnable importing the data from other social

network websites like Facebook, MySpaceProvide a virtual map for users to locate

other users’ locationConnection’s references could be more

diversified

An improved version
