Abstract
The use of an all-photogrammetric mouse as an alternative to other input de vices for softcopy photogrammetric systems is proposed. With this interface , the operator's hand movements are linked to the floating mark by means of a realtime hand monitoring system. Two cameras positioned underneath the o perator's hand locate and track one or more light spots attached to the han d. Through a feedback loop, the user has the feeling of directly manipulati ng the floating mark by hand in the stereomodel. Besides being more intuiti ve than the existing interfaces, the proposed one offers the possibility to measure distances as well as terrain facets in only one operation. Time sa vings of up to 45 percent are reported for DEM collection.
