Introduction
For nearly 30 years, Logitech has been building a bridge for people to digital experiences, and
gaming peripherals have always been their strength. They have an unshakable position in this
market. Among these products, the gaming mouse has always been an innovative product that
Logitech is committed to developing. Their new products can always bring novel experiences to
users. One of the most popular product is the G502 series. The engineering design can be
connected to the player’s computer equipment in two ways: wired and wireless. Compared with
its predecessor, the latest generation G502X ( Figure 1 ) has added function buttons that were not
available before.( MrZac2000, 2023) Players can customize the effects of these function buttons
by using Logitech software. For example, you can reduce your workload by customizing these
buttons, this gaming mouse can also use the macro system to achieve some automated
operations. It can automatically complete a series of batch operations and automatically execute
a series of complex tasks and simplify workload of users. These new designs bring an excellent
experience to users.

Background
Logitech was founded in 1981. (Wikipedia, 2023, para. 3)It is a world-renowned provider of
cloud peripherals originating in Switzerland. It started out as an original equipment manufacturer
(OEM) and now operates in more than 140 countries and regions around the world (Wikipedia,
2023, para. 3). The company operates under the Logitech, Logitech G, Jaybird and Ultimate Ears
brands, and operates in the areas of productivity and creativity, esports gaming, video
collaboration, music and smart home. Logitech implements a multi-brand, multi-category
strategy.. The product business is divided into five segments: keyboard, mouse and other PC
peripheral products category, game category, music category, video conference system and smart
home business. Logitech had the first office in Palo Alto, California in 1982. (Wikipedia, 2023,
para. 4 ) In the same year, the first Logitech mouse, the P4, was released. (Wikipedia, 2023, para.
4 ) The Logitech G1, the first G-series mouse, was released in 2005 ( Figure 3 )was released in
2014. (CDRinfo, 2006.) After many years, the first generation G502 ( Figure 2 ) was released in
2014. ( Walton 2014 ) After receiving good responses from the market , Logitech has continued
to upgrade the G502 since then. The latest generation Logitech G502 X ( Figure 4 ) was released
in 2022. (Knapp, 2023)Compared with G502, the newly released G502x continues the classic
asymmetric ergonomic shape of G502. The size is basically the same and the length and
height are similar, but the new model is slightly wider. There are also slight changes in the
surface texture. The weight is greatly reduced and the counterweight is eliminated. (Knapp,
2023)Secondly, the key has been changed, and a dpi adjustment key has been added, which can
be replaced by a cover plate to prevent misclick. (Knapp, 2023) The biggest change is the feel of
the keys; this time the mouse replaced a new mechanical micro. The feel changed greatly and is a
bit similar to the film keyboard on the mechanical keyboard. The new G502X also received
better reviews than the G502. (Tamas_1337, 2023)

List of Parts and Functions
