Personal digital assistants and color measurement

Abstract

Personal Digital Assistants (PDAs), such as the Visor DeluxeTM by HandspringTM offer a new paradigm for the design and use of computer-driven instruments. This paper concentrates on the methods of integrating a PDA into a portable colormeasuring device and on the enhanced functionality it brings to the instrument. A PDA can be programmed to give these instruments the capability to obtain reflectance data from the spectral analyzer, and translate it into spectral data, color coordinates, and color differences.
