Solution Overview

Problem

Conventional electronic devices provide poor user experiences before explicit user interaction, as they require physical activation to provide feedback and functionality, and lack awareness of user presence for proactive interaction modes.

Innovation Solution

The implementation of a radar system that determines user presence and location, enabling the electronic device to provide input-mode notifications for radar gesture input, allowing users to interact without physical contact and enhancing user awareness of available interaction modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the electronic device waits for explicit user interaction before providing feedback, then power consumption is reduced, but user experience quality deteriorates

Engineering Contradiction:
Improvepower consumptionVSAvoiduser experience quality
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The radar system performs preliminary detection of user presence and gestures before the user explicitly interacts with the device. The system proactively identifies user intent through gesture recognition and prepares appropriate responses in advance, enabling seamless interaction without requiring traditional activation steps while maintaining energy efficiency through targeted radar monitoring.

Inventive Principle:
Principle #10Preliminary action

2Speed

If the radar system continuously monitors for user presence, then responsiveness to user interaction is improved, but energy consumption increases

Engineering Contradiction:
ImproveresponsivenessVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The radar system employs periodic monitoring intervals rather than continuous operation. It alternates between active scanning phases and low-power standby modes, checking for user presence at scheduled intervals. This periodic approach maintains system responsiveness to user gestures while significantly reducing overall energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

3Loss of information

If the device provides multiple input mode notifications, then user awareness of capabilities is improved, but device complexity increases

Engineering Contradiction:
Improveuser awarenessVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system introduces a notification manager as an intermediary layer that handles the complexity of multiple input mode notifications. This manager translates various gesture types and device states into simplified visual indicators displayed to the user. The intermediary absorbs the computational complexity while presenting a clean, intuitive interface that enhances user awareness without apparent device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This document describes techniques and systems that enable an input-mode notification for a multi-input mode. A radar field enables an electronic device to accurately determine the presence or absence of a user near the electronic device. Further, the electronic device can determine whether an application that can receive input through radar-based gestures is operating on the electronic device. Using these techniques, the electronic device can present an input-mode notification on a display of the electronic device when the user is near to alert the user that radar gesture input is available for interacting with the electronic device. This allows the device to provide the user with feedback that can educate the user about what the electronic device is capable of, and allows the user to take advantage of the additional functionality and features provided by the availability of the radar gestures.
