Why run AI on smartphones?
Running AI on smartphones enables operations that are difficult to achieve with cloud AI alone.
Typical cloud AI
Requires a connection and depends on the environment
Depends on network conditions
Cloud transmission is required
Response tends to be slow
Cannot be used offline
On-device AI
Runs entirely on the phone. Works in the field.
Processes on the spot without depending on the network
Easy to operate without requiring cloud transmission
Fast response suited to field work
Stable operation even offline
On-device AI is effective for field operations and real-time use cases.

CASE STUDIES
Case studies
Here are examples of how smartphone AI and recognition technologies have been integrated into real products and workflows.

Product
EdgeOCR
A high-speed OCR engine that runs on smartphones
An OCR engine optimized for logistics and field operations. It performs text and barcode recognition directly on smartphones and supports stable operation even in offline environments.

Case study
Virtual try-on for JINS
Customer experience powered by image generation and conversion
A virtual try-on example that lets users try on different glasses while keeping their own glasses on. Real-time image conversion creates a new purchase experience in stores and online.

Case study
Glasses fit scoring for JINS
Product recommendations powered by a recommendation engine
A case where the evaluation criteria of store staff were learned to provide fit scoring and ranked recommendations linked with virtual try-on. It supports product suggestions while preserving the quality of customer service.

Case study
Age estimation AI for Toshiba Tec
Face analysis and ID OCR that complement human judgment
A case where we developed, end to end, an edge AI that estimates a person's age from camera footage — from model training to the on-device SDK. Combined with ID OCR, it supports age verification that complements human judgment, running fast on the device.

Case study
Verification system for Takebishi
Preventing mix-ups on site with OCR and master matching
A case of a verification app that supports mix-up prevention on manufacturing and logistics floors. It uses OCR to read printed codes and text and automatically matches them against registered master data, instantly preventing operational mistakes.


Case study
Inbound/outbound inspection system for Sanritsu
Systematizing complex rules and know-how to achieve zero mis-shipments and freedom from reliance on individuals
A case where, at the warehouse of Sanritsu, a comprehensive logistics services provider, an inspection system with the functions logistics sites had been looking for resolved challenges around inconsistent work quality and knowledge transfer that depended on skilled staff.


Case study
Verification app for SBS Toshiba Logistics
Verification that handles diverse labels
A case of introducing an OCR app to assist visual checks and manual data entry during receiving and shipping. It handles diverse label formats, preventing errors and improving work efficiency.


Case study
Import/export verification app for MD Logis
Versatile handling of complex matching rules
A case of an app that supports the verification of work orders, cargo, and labels in import/export operations. With versatile handling of complex matching rules, it reduces human error and prevents verification omissions regardless of an operator's experience.
Use cases
Smartphone AI is used in a wide range of field operations.
Label and printed text reading in manufacturing sites
Barcode and text recognition in logistics sites
Inventory and stocktaking efficiency improvements
Product information reading in retail sites
Image recognition for inspection and checking tasks
Adding AI features to existing business apps
