![]() As always with computers it’s the software that guides the hardware choices. When considering the most suitable technology for your business device it’s important therefore to know how the device will be interacted with by its users. Choosing the right touchscreen technology for your business project However, we rarely encounter a use for these types of touch-motions under business conditions. Whilst neither is exclusive to this type of screen it could be fairly said that these motions are easier and a little more natural when less pressure need be applied. Capacitive screens have become loved for use of ‘gestures’ and ‘multi-touch’. Likewise an ordinary stylus or other object cannot be used. Yes it has rapidly become the common touch screen technology found in virtually all touchscreen consumer mobile devices today. Because the technology relies upon electrical interference from a conductive source capacitive touchscreens do not work through most gloves as they are electrically insulating. As the human body is also an electrical conductor, touching the surface of the screen results in interference of the screen’s electrostatic field, the location of which can be detected and sent to the controller for processing. The technology works by detecting changes in electrical conductivity across that layer. ![]() In fact we have devices that support 4 independent touch points on a resistive screen.Ĭapacitive touchscreens involve an insulating outer layer (normally glass) coated with a transparent conductive metal compound. Although multi-touch is rarely a useful feature for most business processes, if required it does not limit your choice of technology. Although uncommon and unknown by many resistive touch screens can and do support multi-touch. One disadvantage however of resistive technology is its vulnerability of being damaged by sharp objects. Because the touch is sensitive to applied pressure the touch source can be any object, either a human finger (including gloved) or any other inanimate pointer. When the panel is touched the layers come into contact at that point which can be accurately detected and sent to the controller for processing. A resistive touchscreen panel is made up of electrically conductive layers. Resistive touchscreens respond to pressure and have been perhaps the most common implementation of touch screen technology due to its low cost. Although this technology was invented in the UK in 1965 it only gathered commercial pace with the spread of computers in the 80s and has witnessed the greatest boost in momentum in recent years from the mobile phone sector. There are almost a dozen different technologies for touchscreens but by far the 2 most common are resistive and capacitive. Touchscreens are technology that shows electronic visual display that can detect the presence and location of a touch within the display area.
