Touch Testing

Infotainment Display Quality Tester

Based on OptoFidelity's proprietary image quality testing technology, we design and build customized robotic imaging stations for QC and characterization of in-vehicle infotainments, HMIs, and even for Head-up Displays.

We also support any custom instrument's (spectrometer, flicker meter, etc.) integration to our systems.

The system can provide high accuracy subpixel level inspection for LED, OLED, LCD, flexible and curved displays from arbitrary locations and angles.

Test Metrics

• Uniformity
• Pixel defects
• MURA
• LED hot spots
• Light leakages
• Color Measurement
• Brightness & contrast
• Flicker Measurements
• Lines & scratches & particle defects

User Interface Manipulator

User interface manipulator is a customized robotic solution for automating repetitive interactions that require operator's interaction with the user interface. This type of simple robotics can be used for functional and reliability tests of all applications that are installed in in-vehicle infotainments. Such apps include, navigation (GPS), CarPlay, Android Auto, any Google apps, as well as checking device configurations, call success rates to system level features like power management. This type of systems can be also used in local labs, remote labs, "test farm" or in mobile (in-driving as well) use. The system also enables testing scenarios where software tools are not available such as for reboot reliability, out of the box user experience or where only vanilla software is allowed and any excess software tools are prohibited.

Test Metrics

• Any interaction (gestures and other types of manipulations) with a user interface
• Any physical interaction from any locations of the smart device

• Optical character recognition and icon detection with machine vision feature

Smart Surface Tester

Smart surfaces are becoming part of our daily life. We see them especially in automotive interiors. OptoFidelity provides customized robotic solutions for measuring performance and functionality of such non-display smart surfaces that has integrated printed electronics, touch controllers, capacitive switches, etc. Smart surface tester is capable of  measuring 3D contours as well. In case of measuring entire fully assembled car components such as a door panel, smart surface testers are usually built with a 6-axis robotics instead of 3-axis gantry type of robotics. Smart surface testers are suitable for end of line testing as well as R&D and QC testing.

Test Metrics

• Performs any touch gestures on smart surfaces
• Force detection, capacitance testing
• Haptic feedback tests such as amplitude, bandwidth, force, velocity and acceleration
• Accuracy, repeatability, precision, jitter 
• Optionally, electrical tests such as short circuit, diode, etc. and surface display quality tests such as luminance, uniformity, color etc. can be integrated as well.

Portable Infotainment Tester

Portable in-vehicle infotainment testers are fully customized robotic products. They can be used for testing of any HMIs, and even non-display surfaces (smart, touch, haptics, capacitance-enabled) as well. Usually, they are used for testing the infotainments and HMIs after they are mounted onto the car. It is also possible to use them during driving (dynamic testing scenarios) conditions. Portable infotainment testers can be also used with 6-axis robots for volume testing or production testing. Portable infotainment testers have a modular design for easy and flexible integration onto the car.

Test Metrics

• Performs any one-finger touch gestures independently from the angle of the display/surface
• Icon detection, and optical character recognition regardless of colors and language of the user interface
• Optionally, force detection, capacitance testing, and haptic feedback modules can be integrated
