Drawing and processing speed can limit or present the development status of software in the game, so it is most prone to consumers and critics. The host controller is the same. The interface mode of the video game controller is constantly moving, and the purpose is to make more effective interaction with the scenes displayed on the screen.
Although the development of most electric play games is focused on software and processors, many major creative and forward-looking ideas are related to the controller. Because the game system and peripheral manufacturers work to improve players and their system interaction, whether they are constantly developing in both human engineering, style, function, or feature.

We may also remember the earliest controller with the quad-square base, of which the central part has a joystick, and a button is also a design for the electricity game in the time. Because only basic directional controls and a selection buttons required at the time, the game can be played, and this controller is fully consistent. Nintendo later issued a Nintendo Entertainment System, where the direction button replaced the game rod, and the second button was also increased, which was a major change in prior art.
Since then, the controller began to become more complicated. Now, the standard player host controller has more buttons than the previous buttons, and each button has more powerful features. The buttons with pressure sensing intermittent effects make it triggered to achieve better control, especially for the brakes and acceleration controls in the driving-based playing game.
The button combination in the fighting game is also used to use the switching capacitor technology. Rumble-packs let players can experience real feelings, and no longer just sound and light effect. Due to the excellent simulation functionality of the game pole, it will reproduce your vitality on the latest controller. Capacitive sensing techniques (capacitive touch sensing) are the latest interface technology, which can improve the availability of game controllers, and the most dazzling mechanical design.
Capacitive sensing technology overview
Capacitive sensing is most commonly used in personal computer touchpads and portable media players. Mobile phone manufacturers have also begun to invest in funds to promote their use and have developed several model sales listings. Simple architecture, equipment waterproof and rugged mechanical design are extremely attractive characteristics of capacitive sensing interfaces.
method
There is several ways to reach the capacitive sensing effect, but the basic elements are fixed. Among them, the capacitive sensor is just a copper plate (PAD) connected to the controller circuit in a printed circuit board. The combination of the sensing button and its connection wire will generate a capacitor around it.
The ground plane, metal support device considered, and other electronic and mechanical components can affect the capacitance value of the sensor. It is generally considered that the sensor capacitance value is equivalent to the capacitance value between it and the ground plane. This capacitance value increases when there is a conductive trigger material (e.g., finger) near the sensor to a certain extent. This is because the conductor itself generates more possible paths between the sensor and the ground, and more paths will have more field lines, which will increase the entire capacitance value.
The front end of the capacitive sensor is composed of a switched capacitor, an internal current source, or a voltage source having an external resistor. These methods are to input voltage values on the sensing capacitor. The voltage value can be processed through the ADC or by the charging time measurement circuit consisting of the comparator, and then reaches the counter or timer. When the digital output value is used by the data processing and decision of the capacitive sensing system, a transition is generated in the ADC output value or the count value in the capacitor generates analog transition. We will discuss all two methods commonly used later, which is the relaxation oscillator and the continuous approximation.
Actual design
It is not difficult to build a capacitive sensor in the actual design. As described above, the capacitive sensor is just placing a conductor sheet on the printed circuit board, usually a copper sheet. This conductor sheet is typically finger, not only directly to the control assembly, but can be directly connected to the control assembly; and can be interacted directly. The induction plate is placed on the surface of the overlay (overlay) below the induction area. It is best not to have any air between the sensor and the cover layer, and the sensor substrate is adhered to the cover layer with a non-conductive bonding agent.
The control circuit can be disposed adjacent the sensor and the closer it. The demand for sensors in mechanical structures determines the configuration of the control circuit. The farther the sensor and the control circuitry, the native capacitance value between the sensor and the ground plane will increase, because the wire will interact with the surrounding environment, and then increase the capacitance value; the longer the distance, the more obvious increments.
Although it is not easy to specify the maximum distance, in general, 6 to 12 inches can be based on the upper limit. The substrate of the capacitive induction application device is not fixed; wherein the most common design is a basic FR4 printed circuit board having a copper wire. In addition, the elastic printed circuit board with copper sheets (usually used in polyamide thin film-kapton) is also common. The elastic substrate can make mechanical design easier, especially on the curved surface. Printing conductive ink printed on elastic substances such as carbon or silver can produce a capacitive sensor at a very low cost, but the printed circuit board and the connector are required because the elastomer cannot be soldered.
Transparent conductive materials, such as indium tin oxide (ITO), is also rapidly used in the application of the touch screen. The ITO sensor is printed on glass or polyethylene terephthalate (PET) film, and then combined with the final design finished product. Although a CHIP-ON-Glass is currently used to control such applications, using an elastic connector on a printed circuit board or hot bar soldering is a more economical approach.
