There are two cases where vibration or audio of the device is used as an -output method:
-As a tacticon to inform users through physical feedback, that -an important event is occurring in the device. For example, when a new message -arrives or a warning note is displayed.
As tactile feedback to indicate to the user that an interaction -event has been made. For example, users receive tactile feedback when they -press a button on the touch screen.
As with sounds, tactile feedback must be used carefully so as not to desensitize -the user to the vibration; the attention grabbing quality remains and functions -so long as the feedback is not too frequent.
-Tactile feedback is enabled for all the Symbian platform UI components. -Tactile feedback can be disabled for the common UI components in an application. -However, this is acceptable only if tactile feedback causes interference with -other device functions.
-The user can choose the level of tactile feedback and turn tacticons ON -and OFF.
-The following table lists the tactile feedback effects:
-The different senses associated -to the skin are called cutaneous senses. These senses are temperature, pressure -(touch itself), pain, tickle, itch and vibration senses. We can characterize -touch as passive or active. Passive touch means the sense of touch itself, -whereas active touch means the touch action.
To communicate through -the sense of touch, we have to stimulate some of the cutaneous senses or the -movement sense. The stimulation of the cutaneous senses or one of them by -a product is called tactile stimulation. Respectively, the stimulation of -the movement sense by a product is called haptic stimulation or just haptics. -Haptics is also used as general term for all issues related to sense of touch, -both human and machine.
Haptic feedback, often referred to as "Haptics", -is the use of the sense of touch in a user interface design to provide information -to an end user. In mobile phones, this generally means the use of vibrations -from the device's vibration alarm to denote that a touch screen button has -been pressed. In this particular example, the phone would vibrate slightly -in response to the user's activation of an on-screen control, making up for -the lack of a normal tactile response that the user would experience when -pressing a physical button.
You can use the following APIs to create -haptic effects:
Available from S60 5th Edition onwards.
It can be used on all S60 5th Edition or later mobile devices. However, -the feedback is played only on touch enabled layouts.
Provides simple functions for triggering various predefined tactile -feedback (vibration or audio) effects.
Enables a consistent user experience in all applications of the mobile -device (an application gives a logical feedback type as an input and the actual -physical effect depends on the mobile device configuration and end user settings).
When the area feedback is used, latency is low for the feedback triggering -(a tactile feedback can already be triggered at the window server level prior -to the corresponding pointer event being delivered to the visible application).
Direct feedback can be easily integrated into
An application can select the logical tactile feedback from certain -types. The produced effect may be different on various mobile devices.
Available from S60 5th Edition, FP2 onwards.
It can be used in touch and hybrid mobile devices.
Provides an interface for accessing Haptics player that can control -different actuator types.
Enables producing of complex vibrator effects, such as an explosion -or machine gun effect in a game, bass boost for a music player, advanced ringing -tone vibration, and so on.
Enables simultaneous playing of different kinds of basis effects and -modifying them when played.
Allows the design of complex effects (using a separate PC application) -that can be loaded on Haptics player for playing.
It may require a special license key for third-party applications -(to be set at runtime) to enable the Haptics player functionality.
Available from S60 3.0 onwards.
It can be used for running device vibrator with given intensity for -a given period of time.
It can be used by a privileged client application to play pulse effects, -which have a very short duration (as the ones used for tactile feedback).
Tactile Feedback Client API for providing tactile feedback in custom -controls (grids, lists, and so on), which will comply with the style of Core -UI components to ensure a uniform user experience among applications.
Haptics API on touch and hybrid mobile devices for producing complex -vibration feedback, which cannot be achieved with Tactile Framework (games, -simulations, demos, and so on).
Vibra API for producing haptic effects such as ringing tone vibration -in those mobile devices where Haptics API is not available or functional.

Tactile feedback can -be set and disabled in a client application or a mobile device in some scenarios, -for example, during phone calls.
