Muralidhar, A., Bishu, R. R. and Hallbeck, M. S. (1995): Ergonomic Glove: Design and Evaluation. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 586-590.

“A new design for gloves was developed based on the principle of selective protection where protective material is introduced in varying levels over different parts of the glove in order to provide protection where it is most needed and at the same time preserve the desirable dexterity and strength capabilities of the barehand, optimizing the trade-off between protection and performance. The pattern for selective protection was arrived at based on existing research, and two pairs of gloves incorporating different levels of protection have been prototyped and are currently being tested using a battery of performance tests and an Algometer test for pressure sensitivity. A battery of tests was developed to evaluate a new glove design which used the principle of selective levels of protection over different parts of the hand in order to maximize protection and minimize loss of dexterity. The test battery comprised of four dexterity tasks and a maximal voluntary grip strength task. The battery assessed the performance of 5 hand conditions, barehand, single glove (one layer), double glove (two layers), and two prototype gloves, one with one layer of protection (contour glove) and the other with four layers of protection over selected parts of the hand (laminar glove). The evaluation compared the performance of the prototype gloves developed with respect to the performance with the double layer glove and the single layer glove. The results indicated that the performance of the prototype gloves was comparable, and that the performance times for the double glove and the two prototype gloves tested were not significantly different. For the test of grip strength, the two prototype gloves tested enabled better performance than the double glove. The assembly task performance for the prototype II (laminar glove) was significantly lower than that of the other glove types tested.”

Batra, Sanjay, Bishu, R. R. and Donohue, Brian (1993): Effects of Hypertext Topology on Navigation Performance. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 175-180.

“This is an empirical investigation of the effects of two hypertext topologies, a hierarchy and a hypertorus structure, on navigation performance under two different network entry conditions, enter at the top of the network and enter randomly at any node. It was hypothesized that hierarchy topology is better only if a user enters the network from the top and the hypertorus topology is better for random entry situations. Thirty two subjects were randomly assigned to one of the four conditions (hierarchy structure with top entry, hierarchy structure with random entry, hypertorus structure with top entry, or hypertorus structure with random entry). The subjects' task is to browse a hypertext network and retrieve facts about ten 1991 automobiles. Performance was determined by elapsed time, number of screens examined, and accuracy. Results showed a strong learning effect over the first ten trials but equivalent performance once subjects on either of the structures for all navigational performance measures except accuracy. The hypertorus topology fosters browsing more than the hierarchy topology. However, the more constrained hierarchy topology fosters more efficient navigation behavior.”

Bishu, R. R., Wei, Wang, Hallbeck, M. S. and Cochran, D. J. (1992): Force Distribution at Hand/Handle Coupling: The Effect of Handle Type. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 816-820.

“Handle location and geometry play an important role in container design and effectiveness. An ideal handle position and angle should minimize stress at L5/S1 and minimize average grip pressure on the two hands with force distributed evenly on both hands. Handles in such a position will be most comfortable for performing a MMH task and reduce the likelihood of compressive injuries on the lumbar spine. Most of the published research on container handles have used the psychophysical, biomechanical, and/or physiological methods to determine handle effectiveness. The force distribution at the exact point of energy transfer, namely the hand/handle interface has rarely been addressed by the scientific community. The intent of this study was to determine the force distribution at the hand/handle interface and use the same to compare the effectiveness of various handle types, positions, and angles. Six factors were tested in this experiment using a fractional factorial design. The pressure at the interface was measured using a number of force sensing resistors (FSRs) in each hand. The results indicate handle positions 2/2, 8/8, and 3/7 to be far superior to position 6/8. The average pressure at the FSR sites appear to be the least at handle angles of 0 degree. Further, the force distribution for the cut-out handle appears to be more uniform than that for the cylindrical handle (circular cross-section). Based on these findings recommendations are made for container designer.”

Jorgensen, M. J., Riley, M. W., Cochran, D. J. and Bishu, R. R. (1989): Maximum Forces in Simulated Meat Cutting Tasks. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 641-645.

“This study attempts to evaluate maximum force capabilities of subjects performing fourteen different simulated meat cutting tasks. The different tasks represent different cutting positions related to the orientation in which the meat is presented and the types of trimming cuts. The experiment was conducted to measure maximum force capability against two constant velocities produced by a Cybex II dynamometer through the range of motion for the simulated meat cutting tasks. The results of this experiment produced a basis for selecting cutting orientations based on force capability for cutting in these fourteen motions. Based on this, the desirability of different cutting orientations for meat trimming jobs has been established.”
