Problems solved by technology

[0004] Park et al. also mention that microelectromechanical system (MEMS) inertial sensors that measure changes in acceleration and angular velocity can be used, but do not discuss them
It does not teach about how to retrieve data from MEMS sensors

Embodiment Construction

[0016] figure 1 is a simplified block diagram of a human-machine interface based on gestures made in the environment 9. A host machine 10 (such as a personal computer) or other device with a graphical user interface or display communicates with a "hold-free" sensor system attached to the body (so that the user does not have to hold or grasp the sensor). In a preferred implementation, the sensors comprise very small MEMS sensors 11-18 linked by wire or wirelessly to a signal accumulation unit 18 which packages the data from the sensors and uses a radio communication link such as Bluetooth ) or use an infrared communication link to transmit the packetized data to the host machine. Certain embodiments may also use wired connections if desired.

[0017] As shown, individual sensors 13-17 are attached to each of the five fingers of the hand, preferably behind the second joint of the thumb and the third joint of the finger. In some systems, sensors can be used on both hands. Fur...

Abstract

A system for interpreting a gesture, comprises, preferably, at least one microelectronic mechanical sensor, which comprises a base suitable for being attached on a first position (such as a finger or a hand) of the human. A signal accumulating unit is connected to the sensor, and has another base suitable for being attached on a second position of the human. The signal accumulating unit comprises a logic for packing and/or interpreting the data about the gesture in a plurality of spaces sensing at one or more sensors. The signal accumulating unit also comprises a communication port for being communicated with a main computer, through which the interpreted data is transmitted to the main computer.

Description

technical field [0001] The present invention relates to gesture-based communication for human-machine interfaces. Background technique [0002] Gesture-based human-computer interface systems have been proposed. For example, US Patent No. 7,259,756 to Park et al. describes a system for sensing and estimating a user's motion for use as a computer interface for selecting information. According to the Park et al. patent, the motion of "motor units" attached to the fingers and hands or other body parts can be sensed, interpreted, and screened, and the results used as input to a computer. The sensors envisioned by Park et al. include image-based sensors as well as giant magnetoresistance GMR-based sensors that are remote from these motion units and not carried by the user. With imaging sensors, information about gestures can be easily blocked by objects because the imaging sensors (cameras) are fixed in the environment or located at specific locations from the user rather than b...
