Abstract: A method of tracking a user's toothcare activity comprises receiving video images of a user's face during, e.g. a toothbrushing session, and identifying, in each of a plurality of frames of the video images, predetermined features of the user's face. The features include at least two invariant landmarks associated with the user's face and one or more landmarks selected from at least mouth feature positions and eye feature positions. Predetermined marker features of a toothcare appliance, e.g. a brush in use are identified in each of the plurality of frames of the video images. From the at least two invariant landmarks associated with the user's nose, a measure of inter-landmark distance is determined. An appliance length normalised by the inter-landmark distance is determined. From the one or more landmarks selected from at least mouth feature positions and eye feature positions, one or more appliance-to-facial feature distances each normalised by the inter-landmark distance is determined.

Abstract: A method of identifying a toothbrush user from among a plurality of different toothbrush users comprises obtaining data indicative of toothbrush motion relative to at least two axes of the toothbrush and filtering the motion data to extract motion data over a predetermined frequency range, such as within a predetermined frequency passband. A motion component distribution of the filtered motion data is determined, and the motion component distribution is compared with a plurality of user-specific motion component distributions to establish the data as indicative of one of said plurality of users. Toothbrushing data captured by a multi-user toothbrush motion tracking system can thereby be ascribed to a correct user within a cohort of users of the system.

Abstract: A laundry system for dispensing one or more ingredient compositions from ingredient reservoirs for supplying to a washing machine drum, the laundry system comprising: (i) an apparatus which comprises a dispensing device and multiple ingredient reservoirs; (ii) said multiple ingredient reservoirs comprising a recycled material and containing the various ingredient compositions in controllable fluid communication with the dispensing device and each ingredient reservoir comprising at least one ingredient reservoir identifier; (iii) said dispensing device being operable to selectively dispense portions of the ingredient compositions from respective ingredient reservoirs as a result of commands by the user to provide a dose of laundry product, and further comprising (iv) an ingredient reservoir control system for controlling said selective dispensing of respective ingredient compositions from specific ingredient reservoirs identified by respective ingredient reservoir identifiers such that the device can selective

Abstract: An augmented mirror for use with one or more user objects, the augmented mirror comprising: a partially silvered mirrored surface; a screen underneath the mirrored surface; a camera including a depth scanner; and a computer module for receiving data from the camera and for providing graphical images to the screen; wherein the sole means of communication with the computer module is via the one or more user objects.

Abstract: A system for measuring the diameter of a human hair (50), the system comprising: a mobile device (20); and a reference card (10) including a hair attachment mechanism (11a, 11b); the mobile device configured to convert an image of a human hair attached to the reference card by the attachment mechanism into a measurement of the diameter of the human hair, using the size of the reference card itself and/or the size of a calibration marker (12) on a surface of the reference card as a size reference.

Abstract: A method of generating a model of a real object derived from a model of a second object, the model of the second object being defined by an array of data points, a number of identifiable components and a number of further components, comprises measuring parameters of corresponding identifiable components of a real object corresponding to the identifiable components in the model the second object. An array of data points defining a first model of the real object is generated the measured parameters.

Abstract: A method is proposed for analysing the usage of a toothbrush made by a subject. The position of the toothbrush is monitored using a position sensor on the brush, and the position of the teeth is monitored by a position sensor mounted in a known fixed relation to the teeth. The resultant data is used to find the relative positions of the toothbrush and teeth over time. Statistical analysis of this data permits the identification of habitual brushing failures by subjects of the toothbrush. The toothbrush may transmit the output of its position sensor to a data analysis unit as a wireless signal. The toothbrush may also be provided with further sensors, such as pH and pressure sensors, the output of which is used in the statistical analysis to enrich the results.
