Ellis, Stephen R., Adelstein, Bernard D. and Yeom, Kiwon (2012): Human Control in Rotated Frames: Anisotropies in the Misalignment Disturbance Function of Pitch, Roll, and Yaw. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 1336-1340.

Comparative misalignment disturbance functions (MDF) have been measured for rotations between display and control axes for pure pitch, roll, and yaw misalignments in a high fidelity virtual environment. Twenty participants manually moved a virtual cursor using position control to touch 3-dimensionally, randomly presented nearby targets having a constant Fitts Index of Difficulty. Results show a peak disturbance near 120 of rotation for all axes with Roll being distinguishably more disturbed. Some reasons for observed anisotropies, nonlinearities and an equiaxial spiral feature are briefly discussed and modeled.

Discontinuities in human movement can provide information about the control law that an operator is using. Such discontinuities are revealed by change points in one or more of the trajectory's spatial derivatives. They are indicative of abrupt variations in the movement and provide information about spatial sampling and error detection. These discontinuities can arise in telerobotic applications, for example, when human operators pause while waiting for time-delayed teleoperation data to arrive or while adapting to account for misalignments between a remote camera and the operator's local manual input reference frame. This paper presents a method for detecting discontinuities from trajectory records during three-dimensional target acquisition movements made by a simulated telerobot operator when display and control coordinates are misaligned. We develop the geometric detection algorithm and illustrate its use on actual data.

The natural role of sound in actions involving mechanical impact and vibration suggests the use of auditory display as an augmentation to virtual haptic interfaces. In order to budget available computational resources for sound simulation, the perceptually tolerable asynchrony between paired haptic-auditory sensations must be known. This paper describes a psychophysical study of detectable time delay between a voluntary hammer tap and its auditory consequence (a percussive sound of either 1, 50, or 200 ms duration). The results show Just Noticeable Differences (JNDs) for temporal asynchrony of 24 ms with insignificant response bias. The invariance of JND and response bias as a function of sound duration in this experiment indicates that observers cued on the initial attack of the auditory stimuli.

We examined whether the inclusion of a third head-slaved "roll" degree of freedom (dof) -- in addition to pitch and yaw dofs -- to control the orientation of a remotely-viewed or computer-synthesized scene can enhance spatial situation awareness. Six subjects were required to match the position and orientation of stationary target markers on a remote taskboard by manually placing response markers on an identical local taskboard. Subjects could only view the remote taskboard through images transmitted to a head mounted display (HMD) from a motorized pitch-yaw-roll camera platform; they could see neither the local taskboard nor their own limbs. Results show that, while systematic overshoot errors in azimuth judgment occurred regardless of the roll condition, the addition of the roll dof to the platform had no statistically discernible effect on the subjects' ability to match the position (i.e., azimuth and elevation) of the remote targets. Absence of the roll dof, however, did affect the subjects' judgment of target orientation when their heads were at maximum elevation (pitch) and azimuth (yaw) combinations.

Adelstein, Bernard D., Johnston, Eric R. and Ellis, Stephen R. (1992): A Testbed for Characterizing Dynamic Response of Virtual Environment Spatial Sensors. In: Mackinlay, Jock D. and Green, Mark (eds.) Proceedings of the 5th annual ACM symposium on User interface software and technology November 15 - 18, 1992, Monteray, California, United States. pp. 15-22.

This paper describes a testbed and method for characterizing the dynamic response of the type of spatial displacement transducers commonly used in virtual environment (VE) applications. The testbed consists of a motorized rotary swing arm that imparts known displacement inputs to the VE sensor. The experimental method involves a series of tests in which the sensor is displayed back and forth at a number of controlled frequencies that span the bandwidth of volitional human movement. During the tests, actual swing arm angle and reported VE sensor displacements are collected and time stamped. Because of the time stamping technique, the response time of the sensor can be measured directly, independently of latencies in data transmission from the sensor unit and any processing by the interface application running on the host computer. Analysis of these experimental results allows sensor time delay and gain characteristics to be determined as a functions of input frequency. Results from tests of several different VE spatial sensors (Ascension, Logitech, and Polhemus) are presented here to demonstrate use of the testbed and method.
