Abstract

The present invention introduces an interactive sitting system that measures and analyzes the forces exerted on a human body during contact with other objects such as a seat to provide a feedback for the user to assess the risk of such forces on the spine and the skin to avoid complications of abnormal or prolonged sitting.

Claims

1. An interactive sitting system that measures and analyzes the forces exerted on a body during its contact with other object to provide a certain feedback for the user whereas said interactive sitting system is comprised of:

a detection unit that senses, collects, and generate initial signals representing the amount, durations, and directions of said forces exerted on said body, where said detection unit can be between said body and said other object;

input unit that receives specific data related to the characters of said body, specifications of said other object, or the like, and generates data representing said specific data and said specifications;

an processing unit that analyzes said initial signals and said data according to an assessment program to generate an ultimate signals representing certain information, or instructions; and

an output unit that receives and convert said ultimate signals into said certain feedback.

2. The interactive sitting system of claim 1 wherein said detection unit is comprised of one or more force sensors that can detect the compression forces and the shear forces that are exerted between said body and said other object.

3. The interactive sitting system of claim 1 wherein said detection unit is a capacitive sensor that can detect the compression force that are exerted between said body and said other object.

4. The interactive sitting system of claim 1 wherein said detection unit is a photocromic sensor that can detect the compression force that are exerted between said body and said other object based on the changing colors due to change in pressure or temperature.

5. The interactive sitting system of claim 1 wherein said specific data includes information describing said body characters such as gender, age, weight, height, body mass index, apparent deformities, medical diagnoses, ambient temperature or the like.

6. The interactive sitting system of claim 1 wherein said specific data include information describing said other object such as material, dimensions, stiffness, inclination, or the like.

7. The interactive sitting system of claim 1 wherein said specific data include the activity that the user performing during sitting.

8. The interactive sitting system of claim 1 wherein said input unit is a selection menu in a graphical user interface that appears on the computer display to present a plurality of alternatives to select of them.

9. The interactive sitting system of claim 1 wherein said input unit is a selection modes where the user can select one of them.

10. The interactive sitting system of claim 1 wherein said processing unit is a microprocessor.

11. The interactive sitting system of claim 1 wherein said processing unit is a computer system.

12. The interactive sitting system of claim 1 wherein said assessment program include certain algorithm, equations, formulas, rules, steps, regulations, or the like that analyzes said initial signals and said data for evaluation purpose.

13. The interactive sitting system of claim 1 wherein said output unit provides audio output, visual output, sensory output, or the like.

14. The interactive sitting system of claim 1 wherein said output unit is a display that provides digital information.

15. The interactive sitting system of claim 1 wherein said output unit is a display that provides graphical presentation such as drawings, 3D models, animation, or the like.

16. The interactive sitting system of claim 1 wherein said output unit is an electrical signal that is interpreted into mechanical movement.
