Abstract: Workstation methods are described which assure that healthy human motions are undertaken while a user is performing tasks over an extended period, as is typical of working on a computer or assembling parts. The workstation includes powered components that are used to change the user's position with time. Biosensors are used to record the physiological state of the users as well as the duration, extent and intensity of user activity. Mechanical sensors are used to measure the position, strain, and acceleration of the workstation joints. Pressure grids are used to measure the contact forces between the user and the workstation. Remote sensors are used to determine user position, and to interpret user gestures. User profiles are maintained that include health history, injuries, fitness goals and physical limitations. A central processing unit uses sensor data and the user's profile to calculate healthy workstation motion routines.
