Mouse

Computer mice are used every day by millions for work and recreation. Although mice are widely used, most are right handed or ambidextrous, and even fewer are left-handed gaming mice.

In more recent times mice targeted toward gamers have recently begun getting lighter shaving off weight, especially in the shell of the mouse. These types of lightweight mice are virtually nonexistent

Market Opening

This diagram depicts an opening in the gaming mouse market, there are no left-handed lightweight mice on the market 


there is an estimated 1.8 billion PC gamers worldwide according to statista.com

Analysis

Persona

Denis is a programmer who works a 9 to 5-job. Afterward, he enjoys streaming and playing games that need high-precision aim. Denis worries that because he is left-handed his non ergonomic ambidextrous mouse is letting him down. Dennis finds his Lightweight ambidextrous mouse uncomfortable causing wrist strain. The left-handed mice he's tried have been too heavy and have low performing Mouse sensors.

Wants:

Research Methods

The messaging app Discord was used to connect to online gaming communities to find out what gamers really wanted in a gaming mouse. In order to collect the data, Microsoft Form’s were posted in multiple Discord servers targeted for PC gamers.


Research Results

From a list of seven mouse qualities three qualities dramatically stood out gamers want a mouse that is Ergonomic, Lightweight, and has a High-performing Sensor.

Arm Ergonomics

The forearm is made of two bones: the radius and the ulna. When your forearm is rotated, like when holding a mouse on a desk, this can cause Fatigue and strain in the muscles for extended periods. An asymmetrical slope helps rotate the forearm in a more natural position.

Human Factors

Using human factor data, the average hand size was determined to be applied to different mouse grip styles. The ideal length of a mouse for a claw grip user is 4.7in.

Hand Ergonomics

When designing a left-handed mouse ergonomics is key. This is a study of what curves and shapes make a mouse ergonomic.

Asymmetrical Slope

Finger Ergonomics

The indentations on the left and right mouse buttons give the mouse a more fitted and secure feel.

Mouse Grips

Holding a mouse can be broken down into three main groups: Claw, Palm, and Fingertip. From the research results, claw and fingertip grip were the most common. Mouse grips that make more contact with the mouse are easier to perform with larger mice and vice versa.

Physical Prototyping

Before digital modeling, the mouse was the first model out of clay to test ergonomics.

[The 3D modeling was done in Fusion 360]

Test Fabrication

The design was printed using a 3d printer and then tested for ergonomics.

Second Phase

Three different designs were made with slight differences in ergonomic design.

Ergonomics Test

Three left-handed people were asked to rank the mice from one through three on comfort and to give feedback

Tester A

  • Favorite mouse: Mouse three

  • Wants: Support in the back of the mouse

Tester B

  • Favorite mouse: Mouse three

  • Wants: Hump closer to the back of the mouse

Refinement Stage

Two more versions of the mouse were further made apllying the feed back given

Tester C

  • Favorite mouse: Mouse three

  • Wants: Bigger scroll wheel and raised side buttons

Research Findings

From the results of the questioning, it was found that a higher hump or arch in the back of the mouse helps give better support to those using the more popular claw grip type.
