Abstract

The widespread and the growing popularity of recreational diving calls for re-thinking on the design of the diving equipment.

Our aim was to identify the man/machine/environment in sports diving using ergonomic methods, and developing a comprehensive (holistic) consumer- based approach for the design of diving equipment in order to increase the number of dedicated recreational divers. 

Data were collected from observations, continuous video recordings, interviews and a detailed questionnaire. The questionnaire was distributed among 130 divers of different certification, gender, and professional experience. The questionnaire was composed of 2 parts: 1. Study of the 33 stages of the diving task, in order to map the critical stages during a regular dive. 2. Evaluation of the diving equipment, by ranked by relative importance of 10 characteristics for each of the 14 major diving items.

Statistical analysis was carried out using group segmentation and correlation of subgroups in the diving population.

We located the most problematic stages in diving process, mostly correlated to transient phases, such as entering and leaving water, dressing and undressing.

Statistical evaluation revealed significant gender and certifications differences in the ranking of the relative importance of various characteristics and properties of the diving equipment.

Results call for re-design of scuba gear as an amphibious equipment; designed for both land, transient and aquatic stages of diving procedure and tailoring for different subgroups of the divers' population.
