Interactive plush projects combine soft-goods construction with electronic components, so the functional brief needs to be clear before sampling begins.
Describe the user action
Define what triggers the function: a button, touch point, sensor, remote control or another input. Then describe exactly what the plush should do in response.
Define the sequence
List sounds, movements, light effects, timing and any automatic shutoff behavior. A simple sequence description helps keep the prototype aligned with the intended experience.
Confirm the power and packaging constraints
Battery type, module placement, access and packaging can affect the plush structure. These details should be considered together during development.
