Heuristic Analysis

Introduction

The RIT campus has a very diverse community that consists of hearing and deaf

people. Although RIT offers many sign language classes and provides interpreters across

campus, communication outside of class is still difficult. The problem we are trying to

overcome is the communication between hearing and deaf people in real-time and in

person without third-party assistance. Our solution would break down the communication

barriers. Using the best attributes of current communication products and new

technology, we are able to envision a product that would bring forth this new era of

communication.

     The products we analyzed were AOL Instant Messenger, WebNote MultiChat

site, and the T-Mobile Sidekick. We choose AOL Instant Messenger because it is the

most popular chat program in the US. We choose WebNote MultiChat because it brings

new features like real-time chat editing with multiple users. The Sidekick was chosen

because it is the leading communication device available on the market today and it is

very popular among deaf students at RIT.

Heuristic Analysis

•     Visibility of system status

It is important for the user to be kept informed about what the current condition of the system is so the user knows what is going on. The user is made aware of the condition of the system through feedback. AIM (AOL Instant Messenger) keeps the user updated with the system status through a variety of feedback. Most of the windows on AIM tell you what the window is about, for example when you receive a message from your friend you get your friend’s screenname displayed on top of the window.
If you want to message a user, you can select their name from your buddy list and send them a message, when the screenname is selected, it gets highlighted, which tells the user the screenname they picked to send a message to. Feedback is also achieved through sound, whenever a message is sent or received a unique sound is played (sounds are customizable by the user). The system status is displayed by the icon in the taskbar, when AIM is signed on the icon is surrounded by a blue circle and when its offline the AIM is by itself, so by looking the user can tell the status of the system.

•     Match between system and the real world

It is important for the system to convey messages in languages and concepts that the user is familiar with. AIM does this pretty well by using languages and concepts that more people are familiar with. AIM uses simple English that most people can comprehend. The icons used in AIM represent everyday things in most people’s lives. When a screenname on your buddy list has an away message, a picture of a note is displayed next to the screenname, signifying that this person has...

AVG Antivirus: An Antivirus Program that Provides Users with Real Time Protection

887 words - 4 pages (M2PressWIRE, 2006). The internal workings of AVG Antivirus include a scanning engine that scans the user’s files and folders then determines if they are infected with a virus by using its known virus detection.

Generic detection effectively finds macro-viruses and script viruses and also looks for variations of known viruses

Deconstructing Architecture Using EvenHookey Essay

2158 words - 9 pages incompatible. Two properties make this solution different: EvenHookey can be harnessed to construct cache coherence, and also our heuristic can be enabled to harness mobile theory. Even though prior solutions to this challenge are promising, none have taken the event-driven method we propose in this work. It should be noted that EvenHookey investigates the analysis of spreadsheets. Along these same lines, the basic tenet of this solution is the

The Power of Media Framing

The implications and limitations of this approach are discussed, in consideration of

Teaching Problem Solving Heuristics at the Primary Level

2481 words - 10 pages ; Verschaffel et al., 1999). Cai (2003) found that when students use problem- solving strategies, they are more successful in solving a mathematical problem. These problem-solving strategies, or heuristics strategies, are procedures that students should take before reaching the calculation phase of problem solving. They are designed to help students understand and organize their responses to answer the problems. While there is evidence that heuristic
