MATT (Case-Study Brief - Objectivity for Smartphone Benchmarking through Display Measurements).

This article will explain how our client measures the touch response time on smartphones, in order to put together a benchmarking that is widely accepted across the industry as the most objective.

Techradar states that smartphones have almost entirely replaced handheld consoles for gaming, and with good reason–they often have excellent screens and plenty of power, while the App Store and Google Play Store both have a large and ever-growing selection of games.

But not all smartphones are good for gaming, and there’s more to consider than just raw power–though that’s certainly a factor.

What is being measured on the handhelds?

Touch-to-display response time = touch sensing, signal processing and display refreshing.

All in small time increments — milliseconds.

Enabling the Touch sampling rate (TSR) vs display refresh rate (DRR) will allow higher responsiveness since the smartphone makers these days are increasing the display refresh rates to 90 Hz or 120 Hz, while the TSR can already be at 120 Hz on your handheld – thus your reflexes can sharpen further while the display is still pending upgrade, or is perhaps used in the battery saving mode .”

How is our Client testing the device you’ll be using to play the next-gen games?

To simulate human gestures on a touch screen, MATT – our robot (link) performs precise and repeatable touch gestures that are measurable to a precision of 0.05 mm at 1.5 m/s.
A high-speed Phantom camera recording 1,200 images per second to capture each frame on a smartphone display.
The camera and the robot are synced via a computer algorithm that senses when touch is applied and processes the video stream from the camera to detect changes on the display.”

“The practice of measuring responsiveness shows how high-frequency touch sampling and display refresh rates are important specs.
Monitoring the processing time and the overall system optimization is extremely critical to getting the best touch-to-display performance in the gaming experience.
Of course, this would not be possible without the objectivity of the tooling – the high-speed equipment and the robot (MATT link) initiating the action being measured and the command for the high-frequency film.”

Do you want to benchmark your mobile against the top guys you compete in the local or international tournaments?

Just drop us or our client a line – and we will make sure you know all about what your device can or cannot do!
Kudos to DXO team for the top benchmarking in the industry!
