## Abstract

A sensor net system including: a sensor node which includes: a sensor which obtains sensor data of a worker; a radio frequency circuit which notifies a server of the sensor data; and a server which includes: a relation list for correlating the sensor data with work status of the worker; a unit for confirming the work status of the worker based on the obtained sensor data by using the relation list; a unit for displaying the confirmed work status on a display unit connected to the server.

## Claims

### Claim 1

A sensor net system comprising:
a sensor node which includes:
a sensor which obtains sensor data of a worker;
a radio frequency circuit which notifies a server of the sensor data; and
a server which includes:
a relation list for correlating the sensor data with work status of the worker;
a unit for confirming the work status of the worker based on the obtained sensor data by using the relation list;
a unit for displaying the confirmed work status on a display unit connected to the server.

### Claim 2 (depends on 1)

The sensor net system as claimed in claim 1, wherein
the confirmed work status is graphically shown in chronological order.

### Claim 3 (depends on 1)

The sensor net system as claimed in claim 1, wherein
the work status is a work category in which the worker is engaged.

### Claim 4 (depends on 1)

The sensor net system as claimed in claim 1, wherein
the work status is a coworker with whom the worker is engaged in a work category.

### Claim 5 (depends on 1)

The sensor net system as claimed in claim 1, wherein
the work status is a location where the worker is engaged in a work category.

### Claim 6 (depends on 1)

The sensor net system as claimed in claim 1, wherein
the work status is a work barometer when the worker is engaged in a work category.

### Claim 7 (depends on 6)

The sensor net system as claimed in claim 6, wherein
the work barometer is a degree of activity or a speech frequency.

### Claim 8

A sensor net system comprising:
a sensor node which includes:
a sensor which obtains sensor data of a worker;
a display unit which displays information on the worker;
an input device for receiving the information on the worker selected by the worker;
a radio frequency circuit which notifies a server of the sensor data and the information on the worker selected by the worker; and
a server which includes:
a unit for confirming work status of the worker based on the sensor data which is obtained when the worker is engaged in a work category correlated with the information on the worker selected by the worker;
a unit for displaying the confirmed work status on a display unit connected to the server together with the information on the worker selected by the worker.

### Claim 9 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the server confirms the work status of the worker by using a relation list which correlates the sensor data with the work status of the worker.

### Claim 10 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the information on the worker is a work category.

### Claim 11 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the information on the worker is a phase of the work category.

### Claim 12 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the information on the worker is a degree of completion of the work category.

### Claim 13 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the work status is a coworker with whom the worker is engaged in the work category.

### Claim 14 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the work status is a location where the worker is engaged in the work category.

### Claim 15 (depends on 8)

The sensor net system as claimed in claim 8, wherein
the work status is a degree of activity or a speech frequency.
