Wireless Handheld Device Motion Detector for Remote GUI Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless handheld devices lack the ability to seamlessly control a graphic user interface (GUI) on external devices and often run out of battery power, limiting their functionality as pointing devices.
Innovation Solution
A wireless handheld device equipped with a housing motion detector that utilizes the device's battery power to transmit GUI control information, such as cursor movement and menu selection, to external devices via a short-range wireless transmitter, effectively transforming the device into a remote pointing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless handheld device is used as a pointing device for external devices, then the ability to control remote GUI is improved, but the device requires additional power source beyond its own battery
Solution Approach 1:
The patent integrates multiple functions into the wireless handheld device: it serves as both a communication device and a pointing device for controlling external displays. The motion detector and wireless transmitter are incorporated into the existing handheld device structure, allowing it to function as a remote control without requiring a separate dedicated pointing device.
2Ease of operation
If a separate wireless pointing device is used to control external GUI, then the pointing functionality is improved, but the device complexity increases
Solution Approach 1:
The patent combines the motion detection capability and wireless transmission functionality into the existing handheld device. The motion detector senses housing movement and the wireless transmitter sends GUI control information, merging these pointing device components with the communication device to create an integrated system rather than separate devices.
3Use of energy by moving object
If the handheld device battery powers the pointing device functions, then the power source availability is improved, but the battery life for pointing functionality is limited
Solution Approach 1:
The handheld device uses its own built-in battery to power both its communication functions and the integrated pointing device functions. The motion detector and wireless transmitter are powered by the device's existing power source, eliminating the need for external power connections or additional batteries.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
a housing motion detector that detects motion of the housing, for example, relative to a surface or other reference point
Implementation Method 2
wireless transmitter, such as a short range wireless transmitter... for transmitting the graphical user interface control information
Data Source
AI summary
A wireless handheld device is disclosed that includes a device housing, a wireless transmitter, such as a short range wireless transmitter, a local display and a housing motion detector that is operative to detect motion of the housing, for example, relative to a surface or other reference point, and outputs graphic user interface control information for transmission by the wireless transmitter to an external device. In one embodiment, a wireless pointing device is operably coupled with a wireless handheld device such as a cell phone or any other suitable wireless handheld device that includes a short range wireless transmitter and/or transceiver to remotely control operation of a graphic user interface for an external device. The housing motion detector utilizes the battery power of the wireless handheld device as its sole source of power or as an auxiliary source of power.
