Paper Abstract:
|
Recent developments in display and interaction technologies afford new IT based applications e.g. for use cases with
several collaborating users. Table-top display environments are among those techniques that are expected to boost the
development of an entire range of new computer applications. While technological development has advanced rapidly,
little research has been done to evaluate the applicability of such techniques for general interaction. In this paper we
present latest results of a study on the efficiency of direct interaction and indirect interaction with a table-top display and
we compare it with indirect input on a conventional vertical display. The results show that users made significantly
shorter cursor movements in the table-top interface than in the conventional vertical interface. In regard to time, task
performance for direct, pen-based input on a table-top interface was even superior to conventional, mouse based
interaction on a vertical display. Users performance was worst for mouse based interaction in the table-top condition
despite shorter travel distances. The results of our work give some interesting criteria for the development of applicable
systems. That is to say, contrary to earlier research we find that the use of a table-top display yields to more efficient
interaction than a comparable vertical display as long as direct input is used. |
