Picoprojector User Identification and Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current picoprojectors primarily function as simple extensions of mobile terminals, lacking the ability to automatically manage and deliver personalized content to multiple users within a household without user intervention, limiting their functionality in providing a unified and controlled multimedia experience.
Innovation Solution
A method and device that detect user identification equipment proximity, query user preferences from a database, and execute actions to retrieve and render audio and video content, enabling automatic operation, parental control, and content sharing among household members through data processing and contactless communication means connected to a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the picoprojector functions as a simple extension of a mobile terminal, then the device complexity is low, but the adaptability to multiple users and automatic content management is poor
Solution Approach 1:
The picoprojector is transformed from a simple terminal extension into a universal device that can serve multiple users and multiple content sources simultaneously. The device incorporates user identification capabilities, database querying for preferences, automatic content selection, and multi-terminal connectivity, enabling it to adapt to different users and deliver personalized content without requiring separate devices for each user
Solution Approach 2:
A database is introduced as an intermediary component that stores user preferences and content information. This database acts as a mediator between the picoprojector and multiple users/terminals, allowing the device to automatically retrieve and apply user-specific settings without direct user intervention, thereby enhancing adaptability while managing complexity through structured data organization
2Ease of operation
If manual configuration is required for each user's content preferences, then the device complexity is low, but the ease of operation and automatic content delivery is poor
Solution Approach 1:
The picoprojector implements self-service functionality by automatically detecting user identification equipment, querying the database for preferred content, and delivering content without requiring manual user configuration or intervention. The device autonomously manages the content delivery process, from user identification to content selection and playback, significantly improving ease of operation
Solution Approach 2:
User preferences and content selections are pre-configured and stored in the database before actual use. When a user approaches the device, the system rapidly retrieves pre-prepared content information, eliminating the need for real-time manual configuration and enabling immediate automatic content delivery
3Adaptability or versatility
If the device shares content among multiple users simultaneously, then the adaptability improves, but the loss of time for content management and coordination increases
Solution Approach 1:
The content buffer enables continuous content delivery to multiple users without interruption or manual intervention. Once content is loaded into the buffer, it can be automatically distributed to multiple users simultaneously or sequentially without requiring repeated configuration or management actions, eliminating time losses associated with content management coordination

AI summary
The method involves detecting identification equipments (2a, 2b) of a user near an autonomous and portable device (1), and obtaining a type of contents and an action to be carried out associated with the contents type for the detected equipments, where the contents are received from a communication network (20) to which the device is connected. The action is executed to obtain audio and/or video contents to be restored in relation to the equipments such that the obtained contents are restored. The equipments are formed as a smart card or a mobile terminal of the user. Independent claims are also included for the following: (1) an autonomous and portable device (2) a computer program product comprising a set of instructions for performing a method for reproducing audio and/or video content from a display unit and/or an audio streaming unit of a device (3) a readable storage medium comprising a set of instructions for performing a method for reproducing audio and/or video content from a display unit and/or an audio streaming unit of a device.
