The overall aim of the project is to provide designers with a tool that can empower them to develop biotelemetry devices in a wearer-centred way and thus improve their wearability. Such a tool is in the form of a wearer-centred design framework, which can help to establish requirements for designing animal wearables that are consistent with the needs of wearers. The framework can be used to identify species-specific wearability requirements for new wearable devices, or to aid the analysis and refinement of requirements emerging from evaluation studies.
