Personal Fitting of Workload Control

To accomplish the personal fitting process, the followings are required:

  • 1. data acquisition and workload control during exercise
  • 2. handling a history database at any time and at any

location

  • 3. updating the control parameters of wellness machines

based on acquired data and a history database.

For conventional wearable units, the following factors were considered:

  • 1. size and weight
  • 2. number of channels and electrical characteristics of amplifiers
  • 3. time for storage
  • 4. active time
  • 5. storing process of acquired data

The function of the wearable units for next generation should be emphasized in transforming physical activities into electrical signals for customizing the properties of human factor related machines in real-time.

Conclusions

  • 1. The new type of wearable units is now necessary for developing

the personal fitting process in the wellness environment.

  • 2. We have produced a prototype of the wearable unit for cycling

both indoor and outdoor exercise. By the wearable unit, the appropriate workload pattern customized by cycle ergometor indoor exercise can be applied to a torque-assisted bicycle in the field.

  • 3. Many opportunities and combinations will be open for users.
  • 4. This approach will benefit for other fields where customization of

workload is required.

  • 5. Distribution of functions promote potential makers easy to join in

this field.
