An input device determines presence of an actual user, instead of an artifact, by using multi-wavelength reflectance spectroscopy. Light sources are operated to illuminate an object with different colors of light at different times. A detector determines, at those different times, intensity data indicative of intensity light of these different colors as reflected from the object. The intensity data is processed to determine whether the object is part of a user or is an artifact. For example, if the object is deemed to be a user, biometric input may be acquired. The biometric input may then be processed to identify the user. The input device may be used at various locations, such as at an entry portal, point of sale, and so forth.

System to determine user presence

A multi-sensor input device includes multi-color lights to illuminate a user's hand with various colors of light including visible and infrared, as well as sensors including a photodetector, a red-green-blue (RGB) camera, and an infrared camera. During operation, sensor data generated by the sensors may represent non-biometric input such as a barcode that is printed or shown on another device's display, biometric input such as images of surface and subcutaneous features of the user's hand, and so forth. The biometric input may then be processed to identify the user. The input device also includes antitamper features to improve security. The input device may be used at various locations, such as at an entry portal, point of sale, and so forth.

Multi-sensor input device

A device for providing even illumination to a user's hand or other object to acquire images of the object for biometric identification of a user, includes a camera, a first light module positioned on a first side of the camera, and a second light module positioned on a second side of the camera. The camera is positioned closer to the second light module. The second light module emits light with a lesser intensity than the first light module. Light bending films positioned adjacent to the light modules redirect emitted light toward opposite edges of the field of view of the camera. Diffusers in the path of the emitted light diffuse portions of the emitted light along the edges of the field of view. Polarizers positioned in the path of the emitted light polarize the emitted light to facilitate visualization of particular features of the hand or other object.
