A basic touchscreen has three main components: a touch sensor, a controller, and a software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system. Our website http://www.HomeTouchSystems.com will explain the difference between all types of touch screen and USB and 232 controllers. This is a link to our USB controller page http://www.hometouchsystems.com/TouchScreen/touch-screen-controllers.aspThis is my best description of a resistive touch screen: The 4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are suspended by many very small spacer dots. When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layer's electrodes. The coordinate X axis of the touch point can be detected by measuring the voltage value thru the top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing voltage input to the top layer's electrodes. All of the above and more can be found at our web site http://www.HomeTouchSystems.com

Do regular camcorders work with green screens?

yes for the most part all cameras work with a green screen, but it all depends on how even the light is across your subject and the green screen and what kind of chroma keyer you are using.


What is the technical difference between a PC monitor and TV monitor?

The difference is resolution. at Normal TV has a resolution of 480. a PC monitor can go way higher than 480. Probably around 1440 or more. But that's the difference. A higher Pixel count. Probably a different Refresh rate too. Technically, a television has tuners; a monitor does not. The monitor doesn't have a tuner it would need help in order to work with an antenna. The help would come in the form of an external digital tuner or a digital-to-analog converter.


How do touch screen phones work?

To allow people to use touch commands that require multiple fingers, the iPhone uses a new arrangement of existing technology. Its touch-sensitive screen includes a layer ofcapacitive material, just like many other touch-screens. However, the iPhone's capacitors are arranged according to a coordinate system. Its circuitry can sense changes at each point along the grid. In other words, every point on the grid generates its own signal when touched and relays that signal to the iPhone's processor. This allows the phone to determine the location and movement of simultaneous touches in multiple locations. Because of its reliance on this capacitive material, the iPhone works only if you touch it with your fingertip -- it won't work if you use a stylus or wear non-conductive gloves.The iPhone's screen detects touch through one of two methods: Mutual capacitance or self capacitance. In mutual capacitance, the capacitive circuitry requires two distinct layers of material. One houses driving lines, which carry current, and other houses sensing lines, which detect the current at nodes. Self capacitance uses one layer of individual electrodes connected with capacitance-sensing circuitry.A mutual capacitance touch-screen contains a grid of sensing lines and driving lines to determine where the user is touching.A self capacitance screen contains sensing circuitsand electrodes to determine where a user is touching.Both of these possible setups send touch data as electrical impulses. In the next section, we'll take a look at exactly what happens.The iPhone's processor and software are central to correctly interpreting input from the touch-screen. The capacitive material sends raw touch-location data to the iPhone's processor. The processor uses software located in the iPhone's memory to interpret the raw data as commands and gestures. Here's what happens:Signals travel from the touch screen to the processor as electrical impulses.The processor uses software to analyze the data and determine the features of each touch. This includes size, shape and location of the affected area on the screen. If necessary, the processor arranges touches with similar features into groups. If you move your finger, the processor calculates the difference between the starting point and ending point of your touch.The processor uses its gesture-interpretation software to determine which gesture you made. It combines your physical movement with information about which application you were using and what the application was doing when you touched the screen.The processor relays your instructions to the program in use. If necessary, it also sends commands to the iPhone's screen and other hardware. If the raw data doesn't match any applicable gestures or commands, the iPhone disregards it as an extraneous touch.All these steps happen in an instant -- you see changes in the screen based on your input almost instantly. This process allows you to access and use all of the iPhone's applications with your fingers.The shape of the screen changes when you need it to as well -- you can shift the perspective from vertical to horizontal by tilting the phone. An accelerometer inside the iPhone lets the operating system know to change the orientation of the image on the screen. This means that you can scroll through long lists of music files on a long, narrow screen, and you can watch movies in a widescreen format. You can learn more about accelerometers in How the Nike + iPod Works and How the Wii Works.


Invention can replace people at work Do you agree or not Give your reasons?

Inventions can and do replace people at work. For example, self-checkout stands have replaced a number of cashiers.Inventions can replace people at work as machines can be programmed to do the work of humans. However, you still need people to design and build the machines, monitor them, and repair them.
