TL;DR: Elderly adults, in comparison to young and middle-aged adults, were less successful in solving the haptic problems and displayed less systematic and logical haptic search strategies.
Abstract: Matching accuracy and strategy utilization in young, middle-aged, and elderly adults was examined in a series of intramodal, haptic match-to-standard problems. Subjects were presented with 2-, 3-, and 4-comparison stimulus arrays and asked to locate by touch alone the comparison stimulus that exactly matched the standard. Results indicated that elderly adults, in comparison to young and middle-aged adults, were less successful in solving the haptic problems. Furthermore, they also displayed less systematic and logical haptic search strategies. Discussion of the results focused on the competence-performance distinction and the relation of selectivity and performance during the aging process.

TL;DR: 39 fourth grade children exposed to a haptic (active touch) match-to-sample task made significantly fewer posttest errors, relative to control subjects, on a visual problem-solving task.
Abstract: 39 fourth grade children exposed to a haptic (active touch) match-to-sample task made significantly fewer posttest errors, relative to control subjects, on a visual problem-solving task. Further, this reduction in errors was comparable to that shown by children who had received specific training in reflective problem-solving. The results were discussed in terms of the possible facilitative effects exposure to a haptic task can have on children's visual problem-solving.

TL;DR: Tasks of a generalized computer interface between human operator and manipulator arm and the mathematics used by the computer to convert control device parameters into handgrip position and orientation are detailed.
Abstract: Tasks of a generalized computer interface between human operator and manipulator arm are discussed. A position control device known as a six degree of freedom joy stick is described. Also, the mathematics used by the computer to convert control device parameters into handgrip position and orientation are detailed.

TL;DR: For example, this paper found that under bimodal conditions, haptic activity appeared to be under visual guidance, and the frequency of palmar grasping and simultaneous exploration was reduced by more than one finger.
Abstract: 48 children 3.5 to 5.2 yr. old inspected blocks supporting two three-dimensional patterns. Subjects allowed simultaneous haptic and visual exploration and those merely seeing the standard showed greater visual recognition of the patterns than children who only inspected the blocks haptically. Compared with haptic exploration alone, bimodal inspection reduced the time children spent touching the patterns and sharply lowered the frequency of palmar grasping and simultaneous exploration by more than one finger. Under bimodal conditions, haptic activity thus seemed under visual guidance.
