In virtual reality (VR) technology, force feedback/display devices are expected to enhance fine sensation and contribute to the user's immersive experience. This is particularly true for glove-type devices. Force display gloves, however, do not have a specific numerical value to indicate display accuracy. In this paper, we report the results of sensory testing and analysis with VR cylindrical objects using a passive-type force display glove. The size discrimination threshold for grasping was determined to be smaller than the nominal average error of the device; however, the threshold was larger than either the actual accuracy of the device or the threshold from an organoleptic test of a barehanded human. We have also identified the possible superimposition of the sensory accuracy errors of the operator with those of the glove. Despite this finding, we have determined that the device shows adequate accuracy for representing cylindrical objects during specific grasping tasks.

To investigate into the errors caused in setting an index by an interpolation at a certain position between 1mm graduations with an accuracy of 1/10mm, results of the calculations performed by 40 persons with slide rules were examined. In these tests, each person was requested to repeat five times a round of calculations-1/(55.0)10, 1/(55.1)10, 2/(55.2)10, ……and 1/(56.0)10. The errors caused in setting an index at each position could be estimated from the difference between the values obtained by the above method and true values. As a result of statistical treatment by means of one-way layout in analysis of the variance, it was found that the error can satisfactorily be represented in such 3 items as mean value and variance of personal biases and variance of accidental error. Obtained results are as follows: 1) Biases set at the middle position of the graduation interval and on the graduation are much smaller than those at other positions. 2) Mean values of personal biases set at various positions are symmetrically distributed to the middle position of the graduation interval and there is a tendency to set the cursor line near to the middle position. 3) Variances of personal biases set at various positions are symmetrically distributed to the middle position and are particularly large at 1/10, 2/10, 3/10, 7/10, 8/10 and 9/10 positions. 4) Accuracy in setting biases at the middle position is almost same as that on the graduation. 5) Due to the effect of training, time required for calculation gradually decreases until about 200-time operations (e.g. 1/55.1).

In this paper, we deal with the control problem to manipulate autonomous multiple agents (a flock of sheep) escaping from an agent (a sheepdog) according to nonlinear interaction. This work was motivated by so-called sheepdog system inspired by sheepdog shepherding: a flock of several thousands of sheep are controlled by only a few sheepdogs in the real world. It is an interesting control system because one or more sheepdogs, who act as a small number of controllers, can control many sheep that cannot be directly controlled, taking advantage of their own maneuverability. For this reason, there have been many studies about this system; however, these studies have been limited to building numerical models or performing simulation analyses. Therefore, we aim to clarify the control principle theoretically. For this purpose, we conduct theoretical analysis for a sheepdog-type navigation system which we design based on a flock control model proposed by Vaughan et.al. in the case that one sheep is controlled by a sheepdog. Moreover, we also demonstrate the results by using simulations to confirm the validity of the analysis.
