Integrated Device Technology Inc. and Immersion Corp. have announced that they are collaborating to drive the adoption of haptics in digital devices. They will work together to provide solutions for OEMs to rapidly implement haptic feedback in touch-enabled products.

Haptics, or touch feedback technology, provides a physical "touch" confirmation to the user when input is received into a system via a touchscreen, slider, touchpad or other digital interface. Through the collaboration, Immersion's TouchSense high-fidelity haptic technology will allow IDT to address a broader range of multimedia applications with its IDT PureTouch silicon solutions, ultimately accelerating touch technology in consumer electronics devices.

"Touch sensor and haptics technologies are key components to the evolution of digital media and consumer electronic devices," said Ram Iyer, VP and general manager for the computing and multimedia division of IDT. "Our touch sensor technology and collaboration with Immersion will allow us to address a broader range of applications while offering our customers the competitive advantages that haptics technology provides."

Multi-modal experience
True multi-modal user experiences encompass sight, sound and touchall physical sensations in CE devices that IDT is improving through its video, audio and touch semiconductor solutions that ultimately allow OEM customers to provide consumers with richer, more complete digital media experiences.

"IDT shares our vision of dramatically improved user experiences, especially in touch solutions," said Craig Vachon, senior VP and general manager of the touch line of business at Immersion. "Enabling haptics at the semiconductor level is a catalyst for further innovation and for accelerated adoption. With Immersion's TouchSense technology in the IDT PureTouch solutions, the power of human touchour most fundamental sensebecomes more widely available for manufacturers to bring to life in their products."

Deployed in over 70 million devices from several of the world's leading manufacturers, haptics technology fully involves the sense of touch to make the user experience with digital devices more efficient, intuitive, fun and more accurate. Applications include integration in products such as CE, mobile phones and handheld devices for commercial and industrial applications.

The IDT PureTouch LDS6010, 6018, 6040, and 6048 capacitive controllers integrate the TouchSense haptics technology, sophisticated software capable of delivering the crisp response required to achieve advanced tactile effects. The driver supports eccentric rotating mass and linear resonant actuator vibration motors, with a smart watchdog timer implemented to save power by activating shutdown mode if no PWM activity is detected. A programmable on-board voltage regulator enables direct connection of the haptics supply to the system battery while still ensuring a consistent haptics experience across the battery discharge curve.
