BACKGROUND:Health has been paid more and more attention in modern society, the health of those special groups, such as the elderly and the disabled, should also be brought to the forefront. As fitness equipment is more and more popular in contemporary, our focus should be transferred to the use of fitness equipment for these special groups.
OBJECTIVE:To put forward the design strategy of fitness equipment control interface, for the special groups to use common fitness equipment comfortably and conveniently.
METHODS:Based on the research of existing fitness equipment control interface, according to the usage habits and cognitive awareness of special groups on control interface, a new design strategy has been put forward using the general design method and ergonomics.
RESULTS AND CONCLUSION:Based on the existing 45 kinds of exercise bikes, 84 kinds of running machines and 129 kinds of treadmil fitness equipments, we found that these equipments are designed for common users in the aspects of design and production process and control interface. Universal design is a design concept beyond the lack of capacity to meet the different needs of different populations, and designed products can reduce or even eliminate the difference in the ability of special populations and the general population in use. The new strategy makes design of fitness equipment control interface generalized and good man-machine interactive, which can meet the demand of the special groups and help them do fitness exercise to improve their health and body function.

BACKGROUND:Rehabilitation training equipments play an important role in the rehabilitation treatment. Because of poor muscle strength and joint mobility in patients, we must guarantee the safety of rehabilitation training equipments.
OBJECTIVE:To design a new suitable man-machine interface that ensures patients can use rehabilitation equipments and even parts of fitness equipments safely.
METHODS:Through user experience research, we found the flaws of the existing rehabilitation equipment. Depending on the principles of ergonomics, we designed a new man-machine interface for upper limb exercise through survey and computer-aided design.
RESULTS AND CONCLUSION:The new man-machine interface program achieves the rapid wear and discharge between patients and rehabilitation training equipment, and importantly, it can automatical y separate people from the equipment when the patient's body discomforts or equipment failure appears. What’s more, this man-machine interface can be promoted to other fitness equipments. As a result, rehabilitation training for patients wil be more convenient.
