Перевод с английского на русский.

The current hand input devices suffer from the same delays that plague the head mount display system, but the users over-compensation is even more noticeable. Because there is typically some interaction with the hand and other objects, absolute position control is much more important here than it would be with head position, where relation motion is usually sufficient. These devices are also extremely limited in their ability to generate any kind of sensory feedback to the user. Based on our research, even to perform gross manipulation tasks with a Data Glove is extremely difficult without some kind of sensory feedback. Any kind of fine manipulation is impossible. Though tactile feedback of some kind may be possible, the quality of this will very likely be extremely low and the cost extremely high for the foreseeable future. perhaps the major failing of the glove-based system is that it requires the user to keep the hand and arm unsupported. This requires the user to employ both agonist and antagonist muscle sets of the arm working agonist each other in order to perform any kind of complex task. The user actually is working harder at this than he would at pushing a real object because, in the case of real object, at least one muscle group is at rest.
Further, there is no true stable surface for the arm to rest against; any king of control requires even more force between the muscle groups.
Our experience demonstrated that a user of such a system when faced with any kind of gross manipulation tasks, could only be expected to use the system for five-minute periods with a large degree of exertion. Any kind of extended activity was precluded.
As a consequence of these drawbacks, it is our expectation that the Data Glove and other similar interface devices will be replaced by more useful devices in the future.
Vocabulary
agonist and antagonist muscle sets-two muscle groups which normally act in opposition to each other.
