Every time a school term begins, my professor always asks us to keep one thing in mind: If you fail to plan, then you plan to fail. As required by our professor, all the graduate students in our research team have to make very detailed research plans at the beginning of a term. Even though it takes some extra work, the results turn out to be good for everybody. Actually, we all have some sort of good contributions at the end of term. Making a good plan is by no means an easy task. This is because it not only requires the setting of a reasonable goal, but also determining realistic steps to achieve the goal. For me, most of time I could not finish everything I have in my plan, but at least I have a clear direction where I am heading. I believe that the same rule applies to the consumer electronics industry. To design a good product, a clear goal should be set before the actual design procedure. Take a gaming mouse design for example, first there must be a theme, then according to the theme, several design goals should be carried out to support the theme. These efforts are necessary for the product to have its own characteristics or personality. In other words, we cannot just use a normal mouse and add some "gaming" features, like RGB LEDs or a fancy logo, and claim that it is a gaming mouse. The designer should have a clear vision of what the mouse’s theme will be like, and how the designed features will match the theme. Above that, the designer should also think about how to make the product unique. For today’s review unit, the GAMDIAS Zeus P1 optical gaming mouse, as implied by its name, should have something to do with Greek mythology. Furthermore, Zeus is the god of all gods in Greek mythology, therefore we are looking for something unusual; something that is not borrowed or inherited from average mice made by GAMDIAS. Will the product meet our expectation of a good gaming mouse? Let us get into details of the review to find out.
