This paper describes an experimental study that compares a graphical user interface for a computer-telephony product designed without the involvement of a human factors engineer to a redesign of that interface designed with a human factors engineer late in the development cycle. Both interfaces were usability tested with target customers. Results from a number of measures, both subjective and objective, indicate that the interface designed with the human factors engineer was easier to use than the interface designed without the human factors engineer. The results of this study show the benefits of involving human factors engineers in the design of graphical user interfaces even towards the end of a development cycle. However, this involvement is most effective when human factors engineers are included as an integral part of the design and development process even at this late stage in the process.

Purpose This paper aims to present the development and experimental study of a fully automated system using a novel laser additive manufacturing technology called laser foil printing (LFP), to fabricate metal parts layer by layer. The mechanical properties of parts fabricated with this novel system are compared with those of comparable methodologies to emphasize the suitability of this process. Design/methodology/approach Test specimens and parts with different geometries were fabricated from 304L stainless steel foil using an automated LFP system. The dimensions of the fabricated parts were measured, and the mechanical properties of the test specimens were characterized in terms of mechanical strength and elongation. Findings The properties of parts fabricated with the automated LFP system were compared with those of parts fabricated with the powder bed fusion additive manufacturing methods. The mechanical strength is higher than those of parts fabricated by the laser powder bed fusion and directed energy deposition technologies. Originality/value To the best knowledge of authors, this is the first time a fully automated LFP system has been developed and the properties of its fabricated parts were compared with other additive manufacturing methods for evaluation.

Counter Surface

Kitchen design is evaluated using counter space, counter location and counter height as the criteria. A survey of apartment kitchens showed that designers generally follow the guidelines for total counter space, but the allocation of counter space to the different work centers makes the designs inadequate. An experimental study shows that the standard 36 high counter surface is not at the correct height for many kitchen tasks and a simple, economical design for adjustable cabinets is presented.

Block Experiment

An experimental study sought to extend understanding of the nosing-to-nosing method for measuring dimensions of steps in a stairway. A human factors expert retained to assist an attorney in a case of injury or death from a stairway fall needs to decide the lateral location for taking the measurements. This experiment was undertaken to provide experts with a justifiable basis for choosing the location. Using a campus stairway and 16 student subjects, a randomized complete block experiment compared their lateral location while performing four tasks—ascending with or without the handrail, and descending with or without the handrail. Results showed task significantly affected lateral distance. Based on findings from this experiment, and some professional judgment, the authors provide recommended ranges for the lateral locations for measuring step dimensions—30 to 38.5 cm for ascending, and 19 to 28 cm for descending.

Design Modification

In an automated airport ground transportation system, passengers who are not familiar with the system nor oriented with respect to the airport, are faced with the problem of selecting a vehicle and destination to change between airlines. The design of an interface between an untrained human user and an automated system requires skillful application of basic human factors principles. An existing system was studied to determine its effectiveness. Passengers were interviewed to identify specific problems. An operational sequence diagram was used to analyze the interface problem. A simplified sequence is proposed in a design modification which can be implemented at minimum cost. A redesign of the complete interface, using the power of the computer which controls the system, and applying human factors principles, results in a greatly simplified operational sequence diagram and is recommended for future systems.
