IoT User Interface with Directional Device Selection and Power Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices require manual pairing and explicit command description, which can be cumbersome and power-intensive, especially for users with visual impairments or those interacting with their hands.
Innovation Solution
Utilizing Bluetooth Angle-of-Arrival (AoA) or Angle-of-Departure technologies to detect the direction of an IoT device from an antenna array, allowing users to address devices intuitively with commands, minimizing power consumption through phased power levels.

Engineering Contradiction Analysis
1Reliability
If manual pairing and explicit device selection steps are implemented, then device control reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting and identifying IoT devices in the environment before user interaction occurs. The controller continuously monitors for devices, pre-establishes their identities and capabilities, and prepares them for control, eliminating the need for manual pairing steps while ensuring reliable device control.
Solution Approach 2:
The system enables self-service by allowing IoT devices to automatically register and identify themselves to the controller without user intervention. Devices transmit their identifiers and capabilities autonomously, and the controller automatically integrates them into the controllable device set, making the operation process hands-free and intuitive.
2Ease of operation
If continuous device monitoring and identification are performed, then ease of operation is improved, but power consumption increases
Solution Approach 1:
The system implements periodic action by having the controller monitor for IoT devices at specific intervals rather than continuously. The controller activates device detection and identification processes periodically, maintaining ease of operation when needed while significantly reducing power consumption during idle periods between monitoring cycles.
