Buy computer mice cheaply: Consumer tips
It is designed to fit the hand, and with it, programs can be controlled and files selected on the computer's user interface using an arrow that moves in sync with the mouse. The movements on a surface are captured by a sensor in the mouse, digitised, and transmitted to the connected computer via cable, wireless, or infrared.
What types of sensors are there?
The mouse is differentiated by the type of sensor. There are three different types of recording mouse movements: ball mouse, LED, and laser. The ball mouse is mechanical and contains a rolling ball. It has the disadvantage of getting dirty very quickly and losing accuracy over time due to wear. Optical mice, on the other hand, work with LED or laser. The movements are captured optically. The surface is illuminated with a light-emitting diode (LED) or a laser. The reflected light is sent as a greyscale image to the mouse sensor chip, from which the movement is calculated. The resolution indicates the number of measurements per second that the mouse makes from the surface. The resolution is given in dpi (dots per inch), and the higher it is, the more precise it works. High resolutions are unnecessary for normal tasks but are more suitable for gaming and some image editing programs.
What should I consider when buying?
The most important criterion when buying a mouse is ergonomics. If the mouse does not fit properly in the hand, it can lead to painful conditions over time. However, how exactly a mouse should be shaped cannot be determined universally, as each hand must adapt individually to the mouse. Additionally, the glide capability should be considered, as this significantly improves control. The surface also plays a significant role in this. The customer also faces the choice of a wireless mouse or one with a cable. Wireless mice transmit the signal via radio (for example, Bluetooth) or infrared and have the advantage that freedom of movement is not restricted by a cable. However, the battery or accumulator must be changed constantly, which can lead to high follow-up costs. Some manufacturers also include a charging station with their wireless input devices, where the mouse can be stored when not in use. Nowadays, almost all mice are equipped with a scroll wheel, which allows the screen content to be moved horizontally or vertically. The operation is intuitive and navigation is comfortable. Normally, mice have two buttons. The buttons can trigger actions. More expensive models may also have more buttons that can be freely assigned using software, increasing comfort. Some models also offer the option to adjust the resolution as needed or come with additional weights so that the user can adjust the balance of the mouse to their own preferences.
