Abstract: A method for capturing biometric data of a human and/or other animal, the method comprising: applying localised compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s), and illuminating the target biological tissue(s); OR illuminating the target biological tissue(s) and applying localised compression of biological tissue(s), so as to reduce blood volume in target biological tissue(s); and detecting and analysing: one or more optical reflectance and/or transmission characteristics of the blood volume reduced target biological tissue(s); and/or one or more spectroscopy characteristics of the blood volume reduced target biological tissue(s).

Abstract: An apparatus for detecting ear structure movements or changes, or changes in pressure in the ear-canal of a user, in order to control or affect the function of an associated device. The apparatus includes a sensor apparatus capable of being worn by the user to be located in or adjacent an ear-canal of the user. The sensor apparatus includes at least one sensor being located and configured to detect and capture sensor data relating to middle ear, ear-drum complex, ear-drum margin, and/or other ear structure movements or changes of characteristics, or changes in pressure in the ear-canal of the user. A device is provided for processing and analysing sensor data from the sensor apparatus. The device analyses sensor data concerning: eye movement or directional auditory attention or focus data, and/or voluntary control data.

Abstract: A sensor which detects voluntary movements of ear structures, including the ear drum complex, which triggers user interfaces of electronic devices to enable communication and other activities by interaction with assistive technology. The method of detecting this voluntary movement may also be used to trigger and control user interfaces in connected devices such as mobile telephones and incorporated into multi-function earphones.
