Linearly arranged banks of hydraulic control levers constitute common control layouts on many specialized pieces of equipment used in agriculture, especially in California. Such controls are used to control multi-function equipment with various types of articulating mechanisms performing both linear and rotary translations in order to effect pitch, roll and yaw movements; also other movements such as clamping and encircling. Stereotypes regarding the control of the motion of a cube with six degrees of freedom by a single control lever were assessed. Results generally were consistent with previous work except for the case of the up/down motion of the cube for which a strongly anomalous phenomenon was found. Stereotypes for the assignment of cube motions to sets of multiple control levers were found to be weak or non-existent.
A survey of research needs in the US agricultural equipment industry was conducted during the latter part of 1983. The purpose of the survey was to determine what information gaps existed in the human factors data base as far as agricultural engineers were concerned and to attempt to stimulate research in those areas where gaps were found to exist. Survey results indicate that answers to some problems can be found in existing human factors references but that survey respondents are not aware of where they can find them. Other survey results point out some interesting problems, possibly unique to agriculture, that need research inputs.
A portable anthropometer made completely from wood has the advantage of being easily built, and the ability to readily disassemble and reassemble it makes it convenient for transporting. Through its use the linear measurement of body and limb dimensions can be made directly from scales incised into the components. It consists of a base, a vertical column, a vertically adjustable cross arm, a vertically adjustable seat, and various other adjustable arms and pointers. Wooden pegs and wedges hold the various components in position.
