Abstract: The invention relates to a method (800), a sytem (100) and a device (102) for measuring the number of laps and/or the distance covered by a person during his/her performance. The invention relates particularly to a distance meter (102) to be worn by the user, which measures the distance covered by the object and comprises a magnetic sensor (212) for determining the direction of a magnetic field (304) external to the sensor relative to the sensor (212). The distance meter (102) to be worn by the user in accordance with the invention also comprises a counter (207), whose value is increased when the measured deviation of the magnetic field exceeds a preset limit, i.e. in the situation where a fitness trainer following a given track turns and starts moving into another direction on the track.

Abstract: The invention relates to a wearable display means (202) of projector type and to a garment (700). The invention relates specifically to a miniature projector (202), which is worn by the user and whose application is compatible with wearable electronic data processing systems (220, 222, 224). One concept of the invention is to project the electronic information generated by wearable electronic devices (220, 222, 224) connected to the projector (202) in the user's field of vision by means of the projector (202). The projector (202) of the invention is equipped with a matrix consisting of at least one Resonance Cavity LED or a micro-mirror and with electronics (300) and optics (314) necessary for projecting. The projector (202) and the electronic devices (220, 222, 224) are integrated in the garment (700) of the invention.

Abstract: The invention relates to a user interface in an electronic hardware arrangement, with an operating device for starting the desired function. The operating device has a fixing point, from which its distance can be adjusted, and means for defining said distance. The function to be performed in each case depends on the defined distance. The invention can be used for instance in portable computers.
