Multi-Touch: a definition of touch screen technology

Multi-touch technology allows a touch screen or touch panel to detect the input of two or more points of contact at the same time. This allows you to use multiple finger gestures to do things like pinch the screen or touchpad to zoom in the Rev, spread your fingers to zoom out, and rotate your fingers for rotating an image you use to be editing.

Multi-touch implementation

Popular applications of multi-touch technology are in:

• Smartphones and mobile tablets
• Track pads for use with laptops and desktops
• Touch tables, touch walls and whiteboards

How does it work?

A multi-touch screen use to have a layer of capacitors, every single synchronises that use to define its position. When you happens to touch a capacitor with the help of your finger, it sends a signal to the processor. Under the hood, the device determines the location, size and any pattern of touches on the screen. Post that, a sign recognition program use to use the data for matching the gesture with the anticipated result. If there is zero match, nothing will happen.

From here, begins a future that is already here.

• Touch screens will run factories

Strategic initiatives such as Industry 4.0 require new automation systems, so the use of sophisticated touch technologies is gaining strength. In this case, it is referred to autonomous systems such as the HMI, which gives Industry 4.0 the ability to share data. Also, to help, in real time Touch screens Industry 4.0 CMG Consultores (and expanding the computing capacity) in the monitoring processes of the factory.

The importance of these technologies, in the coming years, will be such that research and market analysts foresee (until 2018) an average annual increase of this industry of 9.98%.

• Multi-touch technologies, stars of the production lines

Today, two are the most commonly used types of HMI technology in the Industry. On the one hand, non-pressure sensitive capacitive pads. On the other hand, resistive touch pads very useful for working, for example, in warehouses, where the use of thick work gloves is required. All this will mean the evolution of gesture control systems and the increase in connectivity, a consequence (all of this) of the extension of the Internet of Things. From here, new multi-touch technologies they will be, every day, more common use within the production lines… especially in work environments where there is humidity, dust and variable temperatures.

• Multi-touch screens with eight touch points

The commercial use of tablets and Smartphones has also been extended, in recent years, to industrial uses. This has led to a growing demand for multi-touch screens, which provide the operational precision necessary for greater control of production lines. In this Industry 4.0 CMG Consultants multi-touch screen case, new control panels, with up to eight points of contact, allow the operator to perform several tasks at the same time. In other words, that writing with both hands with work gloves is, today, an easier operation to perform and with learning less. This is possible because the employees are already familiar with the use of the interface.
