Both touch screens and hybrid devices are supported by Symbian platform. -Touch screen enables direct manipulation of content and objects, allowing -for far more natural interaction with the device. This means a completely -different user experience and interaction style compared to using a hardware -keypad.
-All applications must be touch-enabled, which means that they can be used -with the touch screen alone, regardless of the presence of a keypad. In Symbian -platform-based touch devices, the important hardware keys are Send, End, Multi-tasking -and Power key.
-The application features must follow the platform support for different -hardware. When designing a touch-enabled Symbian application, the UI must -be designed so that everything can be accomplished by using the touch screen -interface, as the potential target devices may or may not have a hardware -keyboard.
-The touch UI in the Symbian platform is based on the use of resistive and
-capacitive touch screens. In resistive touch screen technology, two
-conductive and resistive layers are separated by a thin space. When an object
-touches this kind of touch panel, the layers are connected at a certain point,
-and a touch event is registered. This allows efficient stylus control, in
-addition to finger touch - unlike capacitive panels, which usually register
-only finger touch. Additionally, resistive touch screen offers a higher resolution
-and more durability. In capacitive touch screen technology, the panel
-consists of an insulator such as glass, coated with a transparent conductor
-(such as indium tin oxide (ITO)). When an object touches the surface of the
-screen, it results in a distortion of the local electrostatic field, measurable
-as a change in capacitance. Then a touch controller measures the frequency
-variations to ascertain the co-ordinates of the object's touch. Capacitive
-touch screen supports
The hardware is supported by various:
-touch-specific components (see
component and UI behavior changes
layout changes, and
additions to the interaction style.
The touch UI is designed to enable full task flow with touch, with minimal -need to switch to hardware keys. Thus, the design ensures that users can complete -a task with the chosen interaction method from start to finish.
-While designing and implementing applications for touch screen devices -based on the Symbian platform, consider interactions that benefit the most -from the touch UI.
-If you can apply direct manipulation of the UI, for example when moving -items from one place to another, or scrolling a page, do not confine the user -with unnecessary scrollbars or have the user resort to options list commands.
-Instead, enable the user to view pages larger than a screen by panning -them directly, and dragging and dropping items rather than marking them and -using menu options.
-Remember that the most intuitive touch screen interactions that can -be performed using a finger are tapping, stroking up/down/left/right, and -the long tap.
Utilize strokes that are easily discovered to the users in the given -context. It should be explicit to the user where strokes can be performed.
Design to ensure that users can complete a task with the same interaction -method from start to finish - touch or hardware keys, stylus, or finger, and -using one hand or both hands.
Aim to optimize system performance and battery consumption to provide -a fluid and reliable touch user experience.
