Abstract
Provided are systems and methods for detecting and associating location information with changes in capacitance on a capacitance sensor assembly of a computing device. Enhancing capacitance detection to include location information can enable generation of image data for display to user showing properties of a concealed object. Rates of change in capacitance drain detected at the sensor assembly coupled with location information can be stored in a derivative image format. The derivative image format of a concealed object can be transformed into an approximation of a conventional camera image. Further processing can be executed to define properties of the concealed object, and identify the concealed object. Further processing can also include model-based analysis and/or property matching to known objects. Image displays can also be correlated to subsequent positions of the device, allowing “x-ray” views of concealed objects
