Consideration of short-term memory for explaining the general difficulty of tasks on a display
Abstract:People tend to feel difficulty in working on displays rather than on paper. We suppose that rather long holding time, for our short-term memory, requested by working on a display is a dominant reason of difficulty with complicated tasks on a display. That's because working on a display, on which we often have to watch multi sheet of documents alternatively, generally force us longer memory holding time than when we are working on multi sheet of real papers. Subjects were requested to process tasks which need cross-reference between multi pages of documents with two viewing conditions of the pages; one was parallel showing of the multi pages and another was alternate showing of the multi pages. Measured results showed longer working time in the alternate showing condition. We regard the increase of the working time in the alternate showing condition as a result of shortage of short-term memory ability more eagerly requested by the alternate showing condition.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
