| Zusammenfassung: | The present invention relates to a sensing device (100) of a pointing device (200), like a mouse. Said pointing device (200) comprises least one light source (110) configured to illuminate a surface (900), at least one first secondary photodetector (121), at least one second secondary photodetector (122) and at least one primary photodetector (123). Each individual storage element of photodetectors are weighted (530) and compared (550) such as to sense said displacement of a pointing device (200). |
