Touchscreen Israk
 
Touch technology is already part of our present. And will be a part of our future. But why do we love touch screens so much? How do they help us in life? Lets take a look at some of the best benefits of touch screens.

1. Speed

Interactive display help us operate any device faster. Think about the time it takes a user to locate a mouse, use a keyboard or trackball. How long it takes to coordinate to the right location on the screen. And activate whatever needs activating on the display. Ensuring a faster input means restaurant customers can be helped quicker. And customer service in hotels, cinemas and stores will be much more efficient. Your customers will be happier and more satisfied. Making them more loyal to your business. Faster input through a touch screen isn't just making customers happy. It can also help us be safer. Saving seconds when operating in-vehicle and security equipment can make all the difference.
 

2. Ease of Use

It has been proven that touch screens are intuitive in use. That is why using a touch screen in an application will help eliminate errors. Selecting the right button or menu item on a screen has never been easier. You just have to point at it. The on screen buttons can be as big as necessary. Ensuring all users can clearly see the buttons and know where to touch to select a function or feature. Touch screens require a lot less coordination from the user. A final benefit of touch screens that help the user is the ability to protect system content from unauthorized entry. Always making sure the right user gets to interact with the right content and information. 

3. Everyone's an Expert in Touch

Pointing at something you want is an instinctive gesture. That is why touch screens have always been labeled as being intuitive. Where many people still don't feel confident enough to use a computer with a mouse and keyboard. But when it comes to touch applications, they don't seem to have this hesitation. Using a touch screen is as simple as pointing at the right location. A mouse and keyboard require some explanation and physical skills. Where a touch screen is instinctively understood. Users feel they can't do anything wrong when using a touch screen device and don't shy away from trying. Isn't that how we learn fastest? By trying? A touch screen makes every user an instant expert. Whether it's someone using a kiosk to print a boarding pass, a worker using industrial machinery, a nurse displaying the patient's information or a waiter taking an order. No experience is required to operate a touch screen.
 

4. Device size

One of the biggest benefits of touch screens is the fact they are usually all-in-one solutions. Touch monitors save space on desks as a mouse or keyboard is not needed. Integrating everything into the display helps save us valuable space. Another benefit is cords and wires can't get tangled, damaged or collect any dust. Integrating data entry with the display saves space in the final device.
 

5. Accessibility

Touch screens can also be of incredible value when accommodating users with physical limitations. A traditional display, mouse and keyboard set up might not work very well for these users. Senior users will probably have difficulty using the mouse and point it at the right location. Or have trouble reading the letters on a keyboard. Using a touch screen will help them operate the device directly, instead of through a tool. A stylus or other pointing device might make it even easier for users to use the display and will enhance the interface.
 

6. Durability and Easy to Clean

Different touch screen technologies offer different protective features. In general touch screens benefit from a durable quality. They are made of glass or a similar hard-coated surface. This makes them easy to clean and very suitable for use in restaurants, hospitals and other public environments. There are even touch screens that are specifically designed for use in harsh environments. They can even be installed outdoors as bus stop or airport applications. A Projected Capacitive Touch Screen is such a rugged touch screen technology. These kind of touch screens are not affected by dirt, rain, grease or dust. Touch screens in general are very well adapted for public use and applications that require heavy usage. But in case you need something a bit tougher, there are many option to protect both your touch screen and the device underneath it.
 

7. Cost Reduction

Using a touch screen interface increases accuracy and reduces time to get used to the equipment. This will improve efficiency and will eventually keep costs down. Users of touch screen devices can respond quickly without making errors. Think about store cashiers being able to help more customers because of the intuitive qualities of the touch screen in the register. This will optimize check out speeds, keeping customers happy. This same intuitive quality will save money when it comes to training users. It simplifies processes and requires minimal training and instructing of end users.
 
We not only believe in the benefits of touch screens to consumers, but also to industrial applications. As this technology is becoming standard and intuitive for next generations, it almost forces manufacturers to integrate their products with a touch interface. If you won't, the competitor will.

Infrared (IR) Touch Panels

Optical (Infrared Optical Imaging)

Infrared touch screen monitors do not overlay the display with an additional screen or screen sandwich. Instead, infrared monitors use IR emitters and receivers to create an invisible grid of light beams across the screen. This ensures the best possible image quality. When an object interrupts the invisible infrared light beam, the sensors are able to locate the touch point.

 Advantages:
• Highest image clarity and light transmission of all touch technologies
• Unlimited “touch-life”
• Impervious to surface scratches

Disadvantages:
• Accidental activation may occur because the infrared beams are actually above the glass surface
• Dust, oil, or grease buildup on screen or frame could impede light beam causing malfunction
• Sensitive to water, snow, rain
• May be sensitive to ambient light interference
• Higher cost

SAW Touch Panels

SAW(Surafce Acoustic Wave) Touch

SAW (Surface Acoustic Wave) touch screen monitors utilize a series of piezoelectric transducers and receivers along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. When the panel is touched, a portion of the wave is absorbed. This allows the receiving transducer to locate the touch point and send this data to the computer. SAW monitors can be activated by a finger, gloved hand, or soft-tip stylus. SAW monitors offer easy use and high visibility.

Advantages:
• Excellent image clarity
• Even better scratch resistance than capacitive
• High “touch-life”

Disadvantages:
• Will not activate with hard items (pen, credit card, or fingernail)
• Water droplets may cause false-triggering
• Solid contaminants on the screen can create non-touch areas until they are removed

Projected Capacitive Touch Panels

Projected Capacitive Touch Panels

Projected Capacitive similar to Surface Capacitive, but it offers two primary advantages: in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves; and it enables multi-touch activation (simultaneous input from two fingers). A projected capacitive is composed of a sheet of glass with embedded transparent electrode films and an IC chip, which creates a three dimensional electrostatic field. When a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points.

Advantages:
• Excellent image clarity
• More resistant to scratching than Surface Capacitive
• Resistant to surface contaminants and liquids (dust, oil, grease, moisture)
• Multi-touch (two-touch)

Disadvantages:

• Sensitive to EMI/RFI
• Must be activated via exposed finger, or thin surgical or cotton gloves


Surface Capacitive Touch Panels

Surface Capacitive Panels

Surface Capacitive are the second most popular type of touch screens on the market. In a surface capacitive touch screen monitor, a transparent electrode layer is placed on top of a glass panel, and covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body; some of the electrical charge transfers from the screen to the user. This decrease in capacitance is detected by sensors located at the four corners of the screen, allowing the controller to determine the touch point. Capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge.

Advantages:
• Better image clarity than Resistive Touch
• Durable screen
• Excellent resistance to surface contaminants and liquids (dust, oil, grease, water droplets)
• High scratch resistance

Disadvantages:
• Requires bare finger or capacitive stylus for activation
• Sensitivity to EMI/RFI

Resistive Film Touch Panels

Resistive Film Touch Panels

5-Wire Resistive Touch is the most widely used touch technology today. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. When a user touches the screen, the two metallic layers make contact, resulting in electrical flow. The point of contact is detected by this change in voltage.

Advantages:
• Can be activated with virtually any object (finger, stylus, gloved hand, pen, etc.)
• Has tactile feel
• Lowest cost touch technology
• Low power consumption
• Resistant to surface contaminants and liquids (dust, oil, grease, moisture)

Disadvantages:
• Lower image clarity compared to other touch technologies
• Outer polyester film is vulnerable to damage from scratching, poking and sharp objects
