Summary Hypothesis/Contents The research was trying to find t o what extent users can interact spatially with a user interface that exists only in their imagination. Furthermore for the three different user studies he hypothesized the following things. 1) Mistakes performed by participants would be fewer than what has been previously reported. 2) Intermitted actions affect visual memory and thus reduce accuracy. 3) As the distance between the index finger and thumb grew,e rror would grow in pointing to the correct point. Methods Three different user studies that involved creating simple drawings, annotating existing drawings and pointing at spaces denoted in imaginary spaces were used to test the hypothesis. The users were asked to draw various graffiti, draw and return to find the same p...
