Reaction Timer.

Working as part of the exhibit design team at FifeX Ltd, I played a pivotal role in the functionality and user experience of this interactive.

Part of the "Operation Ouch" exhibition at the Science and Industry Museum in Manchester, this fun interactive demonstrates the difference in reaction times between light and sound. On button press, a light or sound triggers at a random point within five seconds — the user has to react as fast as they can, and their time is recorded and displayed.

I was responsible for designing and building the entire electronic control system, from the timing logic through to the button inputs and output triggers.

The Brief

Create an engaging, durable interactive for a public museum exhibition that clearly demonstrates the difference in human reaction time to visual versus auditory stimuli — suitable for all ages.

How It Works

The user presses a start button, which triggers either a light or a sound at a random point within five seconds. A timer captures their reaction and displays the result — making the science immediate and tangible.

A wee bit Extra

This project was part of my full-time employment with FifeX Ltd (Scotland). The interactive was produced by our team of exhibit designers — whilst others focused on the drawings, panelling and graphics, I used my experience in electronics to design and build the entire control system.

This interactive is currently installed at the Science and Industry Museum in Manchester as part of their "Bodies and Brains" temporary exhibition.
