Development kits
NECS provides signal input and vibration measurement tools for haptic designers.
Input of various vibration patterns
RMA is an actuator capable of generating a wide range of vibration patterns across the full frequency spectrum, rather than producing only simple vibration patterns within a specific resonant frequency band. To help users take full advantage of these strengths of RMA, NECS provides Development Kit 1 and Development Kit 2, which enable the input of various signals.
Quantitative measurement of haptic results
One of the challenges haptic design engineers face is that it is not easy to quantitatively analyze haptic vibration results. The G-force data provided by actuator suppliers represents the G-force value of the actuator as a standalone unit, not the value of the actuator in a set configuration mounted in a device. As a result, during the development stage, many haptic design engineers rely on the tactile sensation transmitted to their fingertips to make qualitative evaluations of the vibration performance of the set with the actuator installed. For quantitative vibration measurement, there is also the inconvenience of having to use expensive vibration measurement equipment. NECS provides its self-developed mobile G-force meter for developers at a reasonable price.
Development Kit 1 (D-Kit-1)
Development Kit 1 is designed to enable easy evaluation of haptic actuator performance and intuitive testing through application in a variety of environments.
Key features
-
Signal selection and vibration intensity can be controlled using touch-based buttons.
-
A communication function with the MCU is provided so that users can add WAV or MP3 files they create themselves.
-
The MCU can be accessed through a Wi-Fi network, and communication is possible using simple tools such as PuTTY or WinSCP.
-
Button settings can be added or modified through simple code changes.
-
In the button setting code, the button titles and the connected WAV or MP3 files can be freely edited.

Development Kit 2 (D-Kit-2)
Development Kit 2 is designed to support the development and demonstration of haptic feedback systems using NECS haptic actuators. Unlike Development Kit 1, it gives haptic developers greater flexibility in inputting various haptic signals and also allows sensing conditions to be configured.
Key features
-
Based on Infineon PSoC™ 4100S Plus + TI DRV2511
-
Scilab-based .wav to PWM conversion
-
Recognition of actuation sensing functionality
Input sensing
Input sensing is a technology that detects the press and release actions on the haptic feedback surface based on changes in voltage generated by the coil that senses the user’s input.
The following parameters can be adjusted through Development Kit 2.
-
Press Threshold
-
Release Threshold
-
Release Ratio
-
Minimum Delay
-
ADC LSB size

G-force measurement system
The NECS G-force measurement system was developed to support haptic design engineers in their work. At its core, haptics involves vibrating the device to be operated. Haptic development engineers design delicate vibration patterns to provide users with a better tactile experience, while also creating and testing differentiated vibration modes that represent various situations.
The NECS G-force measurement system is a developer-oriented measurement tool that makes it easy to quantitatively capture and display as data the vibrations delivered to the user’s fingertips or other parts of the body by the various input signals designed in this way.
