Abstract

The present invention provides an adaptive infotainment device, comprising a display unit, a processing module, and a network module. The processing module is coupled to the display unit to decrypt and process the multi-media content. The network module is coupled to the processing module to receive the multi-media content and selecting paths and accessing nodes. The network module collects the usage log to be processed by the processing module to generate an accumulated user profile to be fused with user default information in a user default unit coupled to the processing module to generate at least one threshold value so that the display unit is capable of displaying the processed multi-media content according to the threshold value. Hence, the user'"'"'s network behavior can be learned by combining the pre-determined preferences and the past usage preferences so as to generate the most favorable displaying means to enhance the convenience for browsing information.

Claims

1. An adaptive infotainment device, comprising:

a display unit;

a processing module coupled to the display unit to decrypt and process at least one multi-media content; and

a network module coupled to the processing module to receive the multi-media content and capable of selecting paths and accessing nodes;

wherein the network module collects at least one usage log to be processed by the processing module to generate an accumulated user profile to be fused with user default information stored in a user default unit coupled to the processing module to generate at least one threshold value so that the display unit is capable of displaying the processed multi-media content according to the threshold value;

wherein the accumulated user profile and user default information are each assigned weights for determining the threshold value according to a data fusion algorithm;

wherein the weight of the accumulated user profile is determined by the equation x_t=y_t/(Z_t)², where x_t is the weight of the accumulated user profileduring a time period, y_t is the number of usage logs during the time period, and (Z_t)² is the standard deviation of the accumulated user profile during the time period; and

wherein the weight of the user default information weights determined by the equation Σ

<sub>kε

Q</sub>M_k²G_k² , where Σ

_k=1M_k=1 and M_k>

0, G_k is the initial preference set input by user interface, and M_k is a smaller weight given to the initial preference using least squares.

2. The adaptive infotainment device as recited in claim 1, wherein the display unit is a liquid crystal display and the processing module is a digital signal processor.

3. The adaptive infotainment device as recited in claim 1, wherein the network module collects the usage log using at least one antenna unit.

4. The adaptive infotainment device as recited in claim 1, wherein the usage log is stored in a usage log register.

5. The adaptive infotainment device as recited in claim 1, wherein the accumulated user profile is stored in a log calculation unit.

6. The adaptive infotainment device as recited in claim 1, wherein the accumulated user profile is stored according to a pre-determined time slot.

7. The adaptive infotainment device as recited in claim 1, further comprising a reading medium for storing a plurality of widgets, and the plurality of widgets are capable of playing the multi-media content on the liquid crystal display.

8. An adaptive infotainment device, comprising:

a liquid crystal display;

a digital signal processor coupled to the liquid crystal display to decrypt and process at least one multi-media content; and

a routing node module coupled to the digital signal processor to receive the multi-media content;

wherein the routing node module collects at least one usage log to be processed by the digital signal processor to generate an accumulated user profile to be fused with user default information in a user default unit coupled to the digital signal processor to set a plurality of widgets preset in the reading medium by providing different weights according to a data fusion algorithm so that the liquid crystal display is capable of displaying the multi-media content played by the plurality of widgets;

wherein the weight of the accumulated user profile is determined by the equation x_t=yt/(Z_t)², where x_t is the weight of the accumulated user profileduring a time period, y_t is the number of usage logs during the time period, and (Z_t)² is the standard deviation of the accumulated user profile during the time period;

wherein the weight of the user default information weight is determined by the equation Σ

<sub>kε

Q</sub>M_k²G_k², where Σ

_k=1M_k=1 and M_k>

0, G_k is the initial preference set input by user interface, and M_k is a smaller weight given to the initial preference using least squares.

9. The adaptive infotainment device as recited in claim 8, wherein the routing node module, which further comprises a proxy server to receive the usage log collects the usage log using at least one antenna unit.

10. The adaptive infotainment device as recited in claim 8, further comprising a reading medium for storing the plurality of widgets replaced the multi-media content according to the accumulated user profile, and the multi-media content that was previously determined to be played according to the user default information.
