The authors introduce a different approach of applying stereoscopy principles to implement a virtual 3Dpointing technique called stereo 3D mouse Cursor (S3D-Cursor) based on two or more views of an ordinary mouse cursor. The basics of such an idea have already been applied as a by-product of some stereo-based visualization applications with usually less attention to its strengths or weaknesses as a generic alternative of its 2D counterpart in stereoscopic 3D space. Here, they examine if such an idea satisfies all or the main expected requirements of an abstract 3D cursor. Moreover, they analyze its accuracy and evaluate the applicability of this approach in terms of different efficiency factors.
