Abstract The correct application of ICTs (information and communications technologies) to the education of people with physical disabilities requires studies aimed to adapt interfaces. Controlling the design and implementation of input devices would contribute to develop interfaces tailored to the requirements of such context. The purpose of this work is to present the development and validation of the IMUMouse pointer device whose design and implementation is controlledfor researching interfaces that make the most of the interaction capabilities of the devices in adaptation processes. The purpose of the device is to address the needs created by physical disability in upper limps; hence it operates with head movements. Both actions of the IMUMouse, click and move, are performed by processing the data generated by an accelerometer and a gyroscope. The main interaction features of the IMUMouse were assessed by group of 13 people by means of a survey based on Annex C of ISO 92419 standard. The results lead to conclude that the device enables an effective interaction with the computer, as well as the identification of spaces for the application of hardware and software addons to support interaction.
