Lumi Con Sense, a transparent, flexible, scalable, and disposable thin-film image sensor has the potential to lead to new human-computer interfaces that are unconstrained in shape and sensing-distance. In this article we make four new contributions: (1) A new real-time image reconstruction method that results in a significant enhancement of image quality compared to previous approaches; (2) the efficient combination of image reconstruction and shift-invariant linear image processing operations; (3) various hardware and software prototypes which, realize the above contributions, demonstrating the current potential of our sensor for real-time applications; and finally, (4) a further higher quality offline reconstruction algorithm.
