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, analyzes, and provides a feedback on the forces exerted on a body when the body is in contact with an object wherein the interactive sitting system is comprised of:

a detection unit located between the body and the object to sense, collect and generate an initial signal representing the magnitudes, durations and directions of the forces;

an input unit that receives a first data representing the characteristics of the body and a second data representing the characteristics of the object to provide the first data and the second data to a processing unit;

a processing unit that receives and analyzes the initial signal, the first data and the second data according to an assessment program to generate an ultimate data representing the feedback; and

an output unit that receives and converts the ultimate data into a feedback.

2. The interactive sitting system of claim 1 wherein the detection unit is comprised of one or more sensors that detect the pressure and directions of the forces.

3. The interactive sitting system of claim 1 wherein the input unit is a digital display equipped with one or more input tools such as a touchscreen, keyboard, microphone, or camera.

4. The interactive sitting system of claim 1 wherein the body is a human body and the characteristics of the body represent the gender, age, weight, height, body mass index, apparent deformities or medical condition of the human body.

5. The interactive sitting system of claim 1 wherein the body is a human body and the characteristics of the body represent the body habits during the contact with the object.

6. The interactive sitting system of claim 1 wherein the characteristics of the object represent the material, stiffness, dimensions or shape of the object.

7. The interactive sitting system of claim 1 wherein the processing unit is a microprocessor.

8. The interactive sitting system of claim 1 wherein the processing unit is a computer system of a mobile phone, tablet, or computer.

9. The interactive sitting system of claim 1 wherein the assessment program includes algorithm, formulas, or rules to analyze the initial signal, the first data and the second data relative to each other.

10. The interactive sitting system of claim 1 wherein the output unit is a visual system in the form of a digital screen, and the feedback is colors, lights, text, drawings, 3D models, or animation presented on the digital screen.

11. The interactive sitting system of claim 1 wherein the output unit is an audio system in the form of a speaker medium and the feedback is vocal information, sound, alarm or music generated by the audio system.

12. The interactive sitting system of claim 1 wherein the output unit is a tactile feedback system attached to the body, and the feedback is vibrations, motions or forces generated by the tactile feedback system.

13. The interactive sitting system of claim 1 wherein the output unit is a mechanical system that can adjust the stiffness, dimensions or shape of the object, and the feedback is a mechanical adjustment to the stiffness, the dimensions, or the shape.

14. The interactive sitting system of claim 1 wherein the object is a chair and the feedback is information representing the analysis of the healthy standards of the chair relative to the body.

15. The interactive sitting system of claim 1 wherein the feedback represents the risk analysis of the forces exerted on the body.

16. The interactive sitting system of claim 1 wherein the body is a human body and the object is a seat, chair, wheelchair, or car seat.

17. The interactive sitting system of claim 1 wherein the body is not a human body.

18. The interactive sitting system of claim 2 wherein the sensors are electronic, mechanical, chemical, or biological sensors.

19. The interactive sitting system of claim 2 wherein the sensors are attached to the object or located inside the object.

20. The interactive sitting system of claim 2 wherein the sensors are a plurality of chambers that are filled with gas or liquid to sense the pressure applied on the chambers.
