Abstract:
1. An information display system automatically adjusting a projection area, comprising a detection module capturing images of a driver and measuring a distance between said detection module and said driver; a projection device projecting at least one image of driving information onto said projection area before said driver; a data processing module connected with said detection module, using said images of said driver and said distance between said detection module and said driver to recognize facial features of said driver, recording parameters of said projection device, using said facial features and said parameters to estimate a required displacement of said projection area; and a controller connected with said data processing module and said projection device, estimating at least one offset of said parameters of said projection device according to said required displacement of said projection area, driving said projection device to move or rotate according to said at least one offset of said parameters to make said projection device project images of driving information onto a new projection area, wherein said at least one offset of said parameters of said projection device includes a shift distance or a rotation angle of said projection device.
