Test Bench 1.4  
Changelog

By Gregory VoddenUpdated May 26, 2025 at 09:31 am

See our previous 1.3.1 changelog.

Our 1.4 Test Bench update focuses on evaluating adjustable and analog keyboards, including those that use Hall effect or optical analog switches and emerging technologies like tunnel magnetoresistance (TMR) and inductive sensing. We've introduced new tests to better compare these keyboards with each other and with traditional mechanical or non-mechanical models.

For a deeper dive into the investigations that prompted these changes, see our accompanying R&D article.

What's Changed?

We've added a new test group and a single test to an existing test group.

Test Group Description
Adjustable Input Granularity This new test group evaluates how well a keyboard detects input through the entire keystroke.
Switches We've added a new Output Type test, which replaces our existing Analog test.

New Tests

Adjustable Input Granularity

This new test group adds an Input Granularity and, if supported, an Analog Output graph. It also features several measurements, including deadzones for the top and bottom of key travel, a detection ratio that represents how much of the entire keystroke a keyboard can detect, and the keyboard's minimum step distance.

Note that in the photos above, the Wooting 60HE includes both Input Granularity and Analog Output graphs because it supports true analog output. In contrast, the NuPhy Air60 HE lacks the Analog Output graph, as it doesn't support true analog functionality.

Below, you'll find close-up examples of both graphs. Hovering over a data point on the Input Granularity graph reveals the relationship between true switch displacement and the user-defined software setpoint. The Analog Output graph shows how a switch's true displacement corresponds to our analog samples, expressed as a percentage of the total keystroke travel.

Switches - Output Type

Our new Output Type test in the Switches test group identifies whether a keyboard has non-adjustable, adjustable, or analog output. This replaces our Analog test introduced in Test Bench 1.3.1, which grouped adjustable and analog keyboards together. The new test offers a more nuanced, accurate classification.

Most keyboards, such as conventional mechanical models, have non-adjustable input. While many adjustable keyboards are marketed as, or commonly referred to as, analog keyboards, true analog output remains relatively rare.
