Our design is largely based upon Guiard’s observations of how humans distribute work between the two hands in the real world. We show how to apply these principles for the workbenchenvironmentand describe many issues encountered during the design. We ﬁrst develop a framework for two-handed interaction and then explore a variety of two-handed 3D tools and interactive techniques. Related issues include how constraints are implemented and controlled by the two hands and how transitions be-tween one-handedandtwo-handedtasksoccurseemlessly. Informal observations of the system in practice show that users can perform navigation and manipulation tasks easily and with little training us-ing the two-handed environment. One of our interesting ﬁndings was that users often performed two-handed manipulations by combining two otherwise independent one-handed tools in a synergistic fashion. In these cases, we did not program two-handed behaviors explicitly into the system; instead they emerged naturally.","PeriodicalId":308950,"journal":{"name":"Proceedings of the 1997 symposium on Interactive 3D graphics","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133608171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Livingston Andrei State University of North Carolina at Chapel Hill *Delft University of Technology, the Netherlands {jacobsllivingst [state} @cs.unc.edu Systems Registration (or alignment) of the synthetic imagery with the real world is crucial in augmented reality (AR) systems. The data from user-input devices, tracking devices, and imaging devices need to be registered spatially and temporally with the user’s view of the surroundings. Each device haa an associated delay between its observations of the world and the moment when the AR display presented to the user appeto be afkted by a change in the data. We call the differences in delay the relative Iatencies. Relative latency is a source of misregistration and should be reduced. We give general methods for handling multiple data streams with different latency values associated with them in a working AR system. We measure the latency differences (part of the system dependent set of calibrations), time-stamp on-host, adjust the moment of sampling, and interpolate or extrapolate data streams. By using these schemes, a more accurate and consistent view is computed and presented to the user.
