Development kit merges haptics and Bluetooth

September 04, 2014 // By Graham Prophet
TI’s wireless haptic development kit enables tactile feedback prototyping in a wide range of applications, providing system designers with a way to prototype eccentric rotating mass (ERM) motor and linear resonant actuator (LRA) haptic effects.

Using Bluetooth low energy (BLE) and a free iOS app , the Haptic Bluetooth Kit (DRV2605EVM-BT) enables designers to create haptic sequences and LED patterns for tactile feedback, notifications and alerts from a pre-licensed library of more than a hundred distinct haptic effects, eliminating wires and the need to design haptic waveforms.

System designers can use the Haptic Bluetooth Kit to select and test haptic effects from the Immersion-licensed library for virtually any touch-enabled application, from wearables and portable medical equipment to human machine interface (HMI) panels and augmented reality. It includes the DRV2605 haptic driver for ERM/LRA and a SimpleLink Bluetooth low energy CC2541 wireless microcontroller. The kit also includes an LRA and alkaline battery support, which enables designers to mount the board to any surface for quick prototyping and integration. The iOS app allows designers to control on-board LEDs for attention-grabbing lighting effects.

A TI Designs reference design enables designers to quickly add haptic technology to space-constrained, low-power wireless systems, such as touch remote controls, smart watches and portable insulin pumps. The Haptic Feedback with Bluetooth Low Energy and iOS App Reference Design (TIDA-00266) includes schematic design and layout files, test results, sample code and complete user documentation, as well as a CAD file for a wrist-worn form factor.

The Haptic Bluetooth Kit (DRV2605EVM-CT) costs $99. The free iOS app is available on the Apple App Store.
