3-D Pointing Device Power Management via Periodic Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers using infrared communication struggle to efficiently control the complex functions of modern Digital Televisions (DTV) due to limitations in utilizing the unique 3-D motion detection capabilities of 3-D pointing devices.
Innovation Solution
A 3-D pointing device system that includes a receiving unit for operation signals, a display for a movable indicator and pop-up objects, and a controller that manages the display and transmission based on signal reception, optimizing power consumption by deactivating functions when not in use, such as by making the indicator and pop-up objects disappear after a set time if no signal is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the 3-D pointing device continuously transmits operation signals, then the control responsiveness is improved, but the power consumption increases
Solution Approach 1:
The patent implements periodic action by setting the controller to stop transmitting operation signals after detecting no manipulation for a predetermined time period. This allows the device to alternate between active transmission mode and power-saving mode, reducing overall power consumption while maintaining control responsiveness during actual use.
2Ease of operation
If the indicator and pop-up objects remain displayed continuously, then the user interface availability is improved, but the power consumption increases
Solution Approach 1:
The patent applies periodic action by configuring the controller to hide the indicator and pop-up objects after a predetermined time period without manipulation. This creates a cycle between displaying the interface for user interaction and hiding it to conserve power, maintaining ease of operation when needed while reducing power consumption during idle periods.
3Adaptability or versatility
If the 3-D pointing device uses advanced motion detection and display functions, then the control capability for complex DTV functions is improved, but the device complexity increases
Solution Approach 1:
The patent extracts and eliminates unnecessary components and functions from the 3-D pointing device while retaining core motion detection capabilities. By removing redundant features and simplifying the device architecture, the patent reduces device complexity while maintaining sufficient control capability for Digital Television operations.

AI summary
The present invention relates to Digital Television (DTV) controlled by a 3-Dimensional (3-D) pointing device, including a receiving unit configured to receive an operation signal generated by a manipulation for the 3-D pointing device; a display configured to display a movable indicator and at least one pop-up object selectable by the indicator when the operation signal is received; and a controller configured to generate a control signal corresponding to the received operation signal and to make the indicator disappear from the display if the operation signal is not received during a preset first time. According to the present invention, the 3-D pointing device may not transmit an operation signal if the 3-D pointing device is not manipulated during a set time. Accordingly, the period for which the power source of the 3-D pointing device is used can be increased by optimizing the consumption of the power source of the 3-D pointing device.
