Everyone needs sleeping. When disturbed, - sleeping doesn’t ensure physical-psychical refreshing - we can talk insomnia. The sleeping process is studied with polysomnography from the middle of the 20th century. As a result, the characteristics and the diseases of sleeping was revealed. This research is very expensive, furthermore cause discomfort to the patient changing sleeping process while monitoring. There’re numerous researches about sleeping-monitoring for a long time at home without disturbing the patient’s life. I show some of these researches in my study and try to expand it with a promising-looking test method, namely motion-sensor sleeping detection.

We are able to collect information about the individual movements with a sensor placed at the foot of the bed during sleeping without applying body sensor. Classifying these movements we are able to separate the usual movements of the limbs from those awakenings that interrupt sleeping. It is prevailing to note down sleep diary by the patient recording bedtime, awakenings during the night and getting up. This is in practice quite inaccurate and could mislead the doctor researching complaints’ reason. The above mentioned equipment could be suitable to take out the sleep diary or to validate it.

The motion-sensor sleeping detector can’t replace the polysomnographic test in each case but should give an introspection to the patient's home sleep upporting the necessity of a clinical investigation.
