How the Touch Screen Technology Works

There are three commonly used types of touch screen technologies:
1. Resistive
2. Capacitive
3. Surface acoustic wave

1. The resistive type uses a normal glass panel, that is covered by a resistive and a conductive metallic layer and a protective layer (scratch resistant) on top of all this. When you touch the screen, the two metallic layers are joined and the change in electrical field is detected. The circuit on the monitor then calculates the coordinates and transfer them to the touch screen software. Touch screen driver transfers the information about the coordinates to the OS, in a form of events similar to mouse clicks and drags.
This system registers a touch event as soon the surfaces are joined. This means, you can use a finger, a pen or any other item as input. This also makes it most vulnerable to physical damage by sharp objects. The metallic layers only transmit about 75% of the light from the monitor, making its display clarity the lowest of the three.
2. With the capacitive type, a layer storing electrical charge, is placed on the monitor glass. When you touch the layer, a small amount of the electrical charge is transferred to you, decreasing the charge on the layer. Sensors, located at the corners of the monitor, detect a change in electrical charge levels and transfer the information to the touch screen software to process.
The biggest advantage of capacitive type over resistive is that it has 90% light throughput, while the resistive. This gives the capacitive touch screen monitors a much clearer picture. Since this type uses electric charge to detect a touch event, you must use a conductive input, such as a finger.
3. The surface acoustic wave type uses two transducers and a reflector, all placed on the monitor glass plate. One transducer is sending electrical signals to the other and the reflector reflects this signal.
The receiving transducer is capable of detecting and locating any touch event. Since this type has no metallic layers placed on the display surface, they have 100% light throughput, and therefore the most clear picture. Similar to resistive, this type detects touch events by almost any object, except very small or hard items, such as a pen.
These are just the most commonly used types. There are many other touch screen technologies out there, such as strain gauge configuration (from 1960's) or relatively-modern optical imaging technology. And new ones are being developed as we speak.
Touch screen technology has seen a lot of progress during the last few years.
The iPhone has made a revolution in hardware as well as touch screen software. And surveys are showing significant rise in demand for touchscreens computers, for users of laptops, as well as desktop computers.Perhaps, the time to put the mouse away, is finally coming.

Ideas For Marketing Your iPhone Application

Marketing your mobile application can be half of the battle. With over 100,000 applications in the iTunes App Store, it is crucial that you spend time devising a marketing plan for your application. Check out these ideas below on how to successfully market your mobile application.
* Making frequent updates to apps to increase App Store visibility This can be an easy marketing technique and can definitely add extra exposure to your application. It keeps your customers engaged and also allows you to improve upon your mobile app while marketing it at the same time!
* Offering a "lite" version of their paid app to stimulate trial This can be effective to help increase your sales as if a user likes your trial app they are far more likely to purchase your full paid version of the application. This is highly recommended for mobile games and higher priced apps.
* Submitting their app to review blogs
This can make and break your app. If you get favorable reviews its fair for you to expect an increase in sales. But if you receive dis-favorable reviews it will only count against you.
* Making price cuts to stimulate demand
This is an old fashion marketing technique. You can create a sale or 50% off coupon and make your customers feel like they're getting a deal on your mobile app. This marketing technique is recommended after your initial marketing to help recreate customer interest.
* Purchasing advertising on other websites
* Purchasing Google AdWords to attract buyers
* Purchasing / trading for in-app advertising
* Hiring paid Public Relations help This is my personal favorite marketing technique. Public relations helps build brand legitimacy and helps sell your product while informing the public about it at the same time. Invest your time and resources into a excellent press release that is newsworthy and you may find your app featured on all the top technology blogs!
* Search Engine Optimizing (SEO) supporting websites
Before you begin selling your mobile app make sure you spend some time and create a marketing plan to get your app the attention it deserves. With so much competition out there, marketing can be half the battle!
