Abstract: Providing to a human operator a view of displayed images and a view of a piece of hygiene equipment, the apparatus comprising an interface to a sensor which is configured to generate a motion sensor output indicating a movement of a human operator, an access to a data repository which stores base data for generating images representing views of an environment in which tasks by said human operator can be performed, an image generation section configured to generate the images to be displayed based on said base data and said motion sensor output, a sequencer section configured to determine a sequence of situations in relation to a view by said human operator, and an event section which is configured to determine an event in relation to said piece of hygiene equipment and to allocate said determined event in relation to the sequence of situations.

Abstract: A method is provided for detecting presence and absence of a creature. The method includes, receiving an input signal from a radiation sensor; applying a first low-pass filter to the received input signal with a first time constant and generating a first filter output; applying a second low-pass filter to the received input signal with a second time constant and generating a second filter output. The method also includes determining a presence of a creature by comparing a slope of the first filter output to a predetermined value; and determining an absence of the creature based on further processing. A corresponding device for detecting presence and absence of a creature is also provided.
