This system allows the probing or querying of targets in a local area, based on a model of the local environment and specific context variables of interest, to enable a rich, embodied and location–aware spatial interaction. An experiment was conducted to investigate how spatial target selection at different distances, target separations and target widths is affected by a system with added ‘typical’ noise characteristics. Results showed that the successful selection of targets in the virtual environment is maximised with a combination of high angular separation and angular width.</ABSTRACT><URL>http://www.springerlink.com/content/lx1t003l3t5h5n71/fulltext.pdf</URL></RECORD></RECORDS></XML>
