Combine Effects of Varying Frequency, Waveform, Magnitude, and Duration

Rich touch sensations can be created by combining individual effects of varying frequency, waveform, magnitude, and duration. This flexibility means that touch screens can be used for many types of applications by providing a wide range of response:

The programmability of TouchSense technology can be used to further enhance usability, particularly for noisy or distracting environments. For example, pressing the Enter button, no matter where it appears on the screen, could always produce a consistent, strong, and crisp tactile sensation, while buttons for other actions could have a different feel, helping the user to know instinctively whether they’ve made the correct selection.

• Graphical buttons can simulate the familiar up and down clicks of physical buttons
• Menu items can be programmed to supply a light pulse sensation or a confirming push-back response when pressed
• Control switches can exhibit increasing or decreasing vibrations corresponding to motor or fan speed, volume level, lighting levels, or other parameters
• Enter, Next, and other major and minor functions can supply a consistent feel throughout an application
• Scrolling displays can provide a stop sensation when the first or last items have been reached
• Switch controls can exhibit a pop effect
