HMD Location Data Generation via Smartphone Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) used in augmented reality applications are hindered by high manufacturing costs and weight, limiting their widespread adoption due to the need for cameras and sensors to calculate location data.
Innovation Solution
An information processing system that generates location data for HMDs by utilizing a smartphone with cameras to image the environment and the HMD, allowing the HMD to omit these components and reduce its size and weight, while still providing accurate location data for augmented reality applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If HMD is equipped with cameras and sensors to calculate location data, then location accuracy is improved, but device weight and manufacturing cost increase
Solution Approach 1:
The patent extracts the camera and sensor components from the HMD device and relocates them to the smartphone. The HMD retains only the necessary display and processing components, while the smartphone performs the location calculation functions. This separation allows the HMD to achieve accurate location data without carrying heavy cameras and sensors, resolving the contradiction between measurement precision and device weight.
2Measurement precision
If HMD is equipped with cameras and sensors to calculate location data, then location accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent extracts the expensive camera and sensor subsystems from the HMD and transfers their functional role to the smartphone. This allows the HMD to be manufactured with fewer components, reducing production complexity and cost while maintaining location accuracy through the smartphone's computational capabilities.
Solution Approach 2:
The smartphone serves multiple functions: it acts as both a communication device and a location-sensing device for the HMD. By utilizing the smartphone's existing cameras and sensors for augmented reality location calculation, the system avoids duplicating these components in the HMD, thereby reducing manufacturing costs while maintaining measurement precision.
3Weight of moving object
If HMD omits cameras and sensors to reduce weight, then device weight is reduced, but location data generation capability deteriorates
Solution Approach 1:
The patent introduces the smartphone as an intermediary device that bridges the gap between the lightweight HMD and the location data generation requirement. The smartphone captures images and calculates location data, then transmits this information to the HMD, enabling the HMD to function with full location capability without carrying its own cameras or sensors.

AI summary
The present technology relates to an information processing apparatus, an information processing method, and a program that enable a configuration of a head mounted display (HMD) to be simplified. There is provided a generation unit configured to generate: first location data regarding a location of self with respect to a real space; second location data regarding a location of another device with respect to self; and third location data regarding a location of the another device with respect to the real space on the basis of the first location data and the second location data. On the basis of the third location data, image data of an image localized in the real space and to be displayed by the another device is generated. The present technology can be applied to, for example, an information processing apparatus that supplies location data representing a location of an HMD to the HMD.
