The limitations of palmtop computers are their display size and pointing mechanisms. This makes it difficult to use them for direct manipulation of very large objects, such as Wor...
Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation may be used to conv...
This paper describes a method for manipulating a threedimensional object without considering conventional three independent orthogonal views. We apply the direct manipulation to o...
Direct manipulation interfaces are characterised according to the representation of the task domain: the domain objects and the effect of user operations on those objects. In the ...
