Touch screens
Touch screens are a major part of our daily lives from mobile phones, tablets, Interactive white boards, way finding directories, interactive tables, self ordering kiosks to navigation systems. The number of touch screens and technologies are increasing as the number of touch screen applications increase and touch technology becomes cheaper.
- So what are the different types of touch technology?
- Which touch screen technology is better?
- Are there applications and price points that make one technology suited to specific applications?
Projected Capacitive Touch Screens
In recent times Projective Capacitive touch is proving to be the technology of choice. Projective capacitive or PCAP touch screens as it is generally referred to is the technology that is used in our current mobile phones and tablets due to its rapid response time and accuracy. Most PCAP touch screens are made of a matrix of rows and columns of conductive material layered between sheets of toughened glass and the LCD panel, when a finger touches the glass a low voltage is sent to the grid, which detects the coordinates of the touch point.
These touch screens perform well in high ambient light environments, they have a toughened glass front making them ideal for high traffic public spaces. No recessed bezel is required so PCAP touch monitors are easy to clean with smooth gesture recognition and multiple users can use the multi touch screen at one time with up to 50 simultaneous points registered at once.
With the specialised cooling system the touch screens can be mounted landscape, portrait or laid face up in tables and counters
Infrared Touch Screens
Infrared touch technology commonly known as IR touch is the most widely used touch screen technology in commercial applications and has been the industry standard for a number of years. A number of LED lights and sensors are embedded into the monitor’s bezel. These LED’s create an invisible grid in front of the LCD screen, when a finger, or other solid object breaks the grid, the sensors can detect the touch point.
Due to this a raised bezel is always required by IR touch screens to accommodate the LED lights and sensor. Infra red technology is the most cost effective making it ideal for Interactive White Boards (IWB’s) where a finger or pen can be used, video walls overlays and touch screen kiosks
How to Create touch screen content?
Our touch screen content management system
allows touch content to be created easily and inexpensively without the need to be technical or for special coding ability. Simply drag and drop images onto the page to create content pages and then create a flow diagram between these pages to select how each page or action links to the other.
Examples of what the touch screen CMS can be used for are way finding, 3D walk through, presentations, QSR self ordering kiosks, display sales Centre’s and many more.
