How To Design Touch Panel

How to Design Touch ScreenThe touch screen is now becoming more and more popular.Designing touch screen is not difficult, but you need to consider several things.

User Consideration.
1.Consider who will be the user for the touch screen, whether it be the elderly, teenagers or the disabled. This affects not only the overall look of the screen (the number of icons), but also the complexity of use.
2.Remember that a person's finger can never be as small as a computer mouse cursor or stylus. Limit the number of icons on your screen so that the wrong icon isn't selected by mistake.

3.Choose icon symbols that don't require a lot of thought to understand. Users who opt for a touch screen don't want to be slowed down by reading--they just want to select and go.  


Tecnical and other Consideration

1.Think about your possible platforms for programming. A cross- platform approach will allow the touch screen design to be utilized in the largest number of devices, but depending on the specific uses intended for the screen, this may not be an issue. All you need to do to design a cross platform screen is to select a programming language that is compatible with the majority of operating systems and applications. Compare the pros and cons of each language as you do this and consider whether the language you select has room for growth for future developments and updates.

2.Pair your icons with sounds so that the user knows that their selection was accepted by the device. Doing this means that your application and design has to be compatible with audio hardware and formats, so you'll need to select what audio files to use and figure out how to connect them to the selection process in your programming. You also should consider a graphical alternative to the sound for those who want to turn audio off or who are hearing- impaired. Connecting these applications is done in the programming for the screen, so the method of connecting these audio or graphic files will vary based on the language you use and the operating system you are working with.

3.Avoid cursors, scroll bars, drop-down menus and double clicks. All of these things increase the complexity of the screen and decrease efficiency. Make a list of alternatives, such as using an icon to turn the page rather than having a long list of text that requires a scroll bar.

4.Remember your color scheme. You will want your icons to stand out individually and from the background. Overall, remember that bright backgrounds hide fingerprints better than dark ones do. The color scheme can be determined in your programming, and you can provide the user with the option of different skins so that they can select for themselves what they like.
