## Abstract

A system and method for observing a personal networking event which shares the position of a number of friendly participants with other participants within a group. In one form, the position of unknown participants meeting certain criteria is also displayed to a user or one or more friendly participants. The views are selectable by friendly participants on, for example, a GPS equipped cell phone, to include a view from the participant's position, zoom, pan, and tilt views, or views from another friendly location or from another geographic location, giving increased situational awareness and identification of participants. Other information can be shared among friendly participants, including social information, status and directions.

## Claims

### Claim 1

A system for identifying a friendly participant in real time in a personal networking situation comprising:
said friendly participant having a GPS receiver for determining said friendly participant's position and a participant radio for transmitting said friendly participant position in real time;
a server for receiving said friendly participant position from said participant radio and for storing participant information including position information and social information;
a radio coupled to said server for transmitting said friendly participant position; and
a portable device accompanying a respective user, the portable device including a GPS for determining the user's position and a radio for receiving a friendly participant position from the radio coupled to said server, the receipt of said friendly participant position being based at least in part on (i) a user choice of information and (ii) said participant information,
a graphics display selectable by the user to display multiple views of the personal networking situation, wherein at least one of the user views selectable on the display is the perspective view from the user's position to said friendly participant position, and wherein augmented reality identifies the position of said friendly participant.

### Claim 2 (depends on 1)

The system of claim 1, including one or more friendly participants where participant information comprises position information, social information, or both, and where position information and social information are selectively published, where each participant chooses the information to publish.

### Claim 3 (depends on 1)

The system of claim 1, wherein said user and said friendly participant possess handheld devices comprising cell phones which include a GPS receiver for determining the cell phone position and a mechanism to selectively publish said position and identity to a particular group connected to a cellular network.

### Claim 4 (depends on 1)

The system of claim 1, including a number of friendly participants each having a handheld device wherein said number of handheld devices each include a GPS receiver and a processor for transmitting said participant positions, said server having a processor for comparing said user position with said friendly participants' positions, and said graphics display identifies said friendly participant positions from said user's position.

### Claim 5 (depends on 1)

The system of claim 1, wherein said augmented reality is an augmented reality overlay and said user's view from the user's position uses said augmented reality overlay to identify said friendly participant.

### Claim 6 (depends on 1)

The system of claim 1, wherein multiple views from different viewpoints are selectable and one of said user's different views is an overhead view of the personal networking area of interest.

### Claim 7 (depends on 1)

The system of claim 1, wherein one of said user's different views is an enlarged zoom view.

### Claim 8 (depends on 1)

The system of claim 1, wherein the graphics display is selectable by the user to display appended information of a participant.

### Claim 9 (depends on 1)

The system of claim 1, wherein said social information includes a group identity and a participant position is received by said user based at least in part on said user's choice of group identity.

### Claim 10

A method for observing a personal networking situation in real time comprising:
a) determining a first position of a participant at said situation in real time;
b) transmitting the determined first position of said participant;
c) equipping a user with a device having a graphics display and a GPS for determining a user location;
d) receiving the determined first position at the user's device;
e) selectively receiving social information of one or more participants at the user's device based at least in part on participant social information;
f) viewing on the graphics display of the user's device an indication of the first participant position at said situation using augmented reality, and one point of view is a perspective view from said user GPS location to said first participant position; and
g) repeating steps (a), (b), and (d) for a second position of said participant; and
h) viewing on the graphics display of the user's device an indication of the second position at said situation using augmented reality and one point of view is from said user GPS location to said second position.

### Claim 11 (depends on 10)

The method of claim 10, wherein said device includes a GPS receiver for determining said user's location at the situation and said one point of view is from said user's location, and said graphics display comprises an augmented reality overlay.

### Claim 12 (depends on 10)

The method of claim 10, including multiple points of view, wherein one of said points of view is an overhead view of said situation.

### Claim 13 (depends on 10)

The method of claim 10, wherein said participant position determining step comprises equipping said one or more participants with a GPS equipped cell phone.

### Claim 14 (depends on 10)

The method of claim 10, wherein said one or more participant positions are transmitted to a server, wherein said user's device communicates and authenticates with said server, and wherein said server communicates said one or more participant positions to the user's authenticated device.

### Claim 15 (depends on 14)

The method of claim 14, wherein said user's device authenticates with said server and said device is remote from said situation, and said one or more participant positions are communicated over a network to said user's device.

### Claim 16

A method of viewing a personal networking situation in real time by a user comprising:
selecting a first position by said user;
wirelessly receiving multiple GPS positions of a friendly participant in real time as the participant moves at said personal networking situation by said user;
displaying the networking situation where at least a portion is a graphic rendered in real time, including:
rendering an augmented reality indication in real time of said friendly participant positions at said personal networking situation, with the friendly participant identified and the positions of said identified friendly participant displayed;
using said user selected first position as the viewpoint for viewing the augmented reality indication of said identified friendly participant from said user selected first position to said friendly participant positions, wherein said viewpoint is a perspective view and not an overhead plan view of said situation; and
selectively changing the viewpoint of said indication from said user selected first position to a user selected second position.

### Claim 17 (depends on 16)

The method of claim 16, including rendering appended information of said participant.

### Claim 18 (depends on 16)
