Procedures for Using HiLens

Huawei HiLens provides device management, skill development, data management, skill market, and product management functions for three types of users, helping them develop AI skills for computing devices.

For details about how to use HiLens Kit devices, see the HiLens Kit User Guide.

The functions users need vary depending on application scenarios. This section describes the procedures for using Huawei HiLens based on the three types of users and their application scenarios. You can quickly understand functions provided by Huawei HiLens by reading Huawei HiLens Function Overview and click the links in this table to go to the corresponding sections to learn details.

The procedures for using HiLens are as follows. Only the main procedures are listed here. For details about other management operations, see Huawei HiLens Function Overview.

Prerequisites

Before using Huawei HiLens, you need to create a Huawei Cloud account. Through this account, you can have access to all Huawei Cloud services and pay only for the services you use.
Huawei HiLens depends on other services. Before using this service, you need to obtain the permissions of other related services, including ModelArts, Object Storage Service (OBS), and Software Repository for Container (SWR). For details about the relationships between Huawei HiLens and other services, see Related Services.

Common Users Use Skills

Common users refer to users who use HiLens Kit devices for intelligent surveillance in scenarios such as smart home, shopping malls, campuses, and construction sites.

**Table 1** Procedure for common users
Procedure	Description	Detailed Instructions
Registering HiLens Kit Devices	Connect to the HiLens Kit devices you purchased and register them with the Huawei HiLens platform to connect them to the cloud.	Registering a HiLens Kit Device Registering a Device Using SSH
Upgrading HiLens_Device_Agent Firmware	Upgrade the HiLens_Device_Agent to version 1.0.7 or later.	Upgrading HiLens_Device_Agent Firmware
Purchasing Skills	Purchase existing skills or custom skills you need from the skill market and install them onto your devices to deploy AI capabilities. In the skill market, select the skills designed to run on Ascend chips.	Purchasing Skills
Installing Skills	Install the purchased skills on your devices.	Installing a Skill
Viewing Skill Performance	View the device data and how the skills have been performing.	Managing Data

Developers Develop Skills on the Management Console

Huawei HiLens provides a skill development platform, on which you can develop skills to run on Ascend 310 or HiSilicon Hi35xx series chips based on site requirements. Skills tailored-made for Ascend 310 chips can be directly installed on HiLens Kit devices.

Devices running HiSilicon Hi35xx series chips typically have a small on-chip memory and small capacities in other dimensions as well. It is challenging to develop skills that run well on such devices. You need to optimize the skill models. If you encounter any difficulty, contact Huawei HiLens platform personnel for support.

In the process of developing a skill, you need to deploy the skill onto a test device to see how the skill performs. Therefore, developers are advised to purchase at least one HiLens Kit device.
Developers need to train AI models locally or in ModelArts to develop skills. For details about how to train models in ModelArts, see Model Training Overview.

Figure 2 shows the skill development procedure, and Table 2 describes the procedure in detail.

**Table 2** Procedure for skill development by developers
Procedure	Description	Detailed Instructions
Registering Devices	Register the devices to the Huawei HiLens platform and connect the devices to the cloud. Huawei HiLens supports HiLens Kit devices and Atlas500, Atlas 800, IVS 1800, and more devices that are being tested for compatibility.	Registering HiLens Kit Devices
Developing Skills	Creating a Skill Using a Skill Template: Obtain a skill template (containing the algorithm model and logic code) provided by Huawei HiLens to quickly create a skill.	Obtaining Skill Templates Creating a Skill Using a Skill Template
Developing Skills	Creating a Skill Using an Empty Template: To meet more service requirements, you can develop an algorithm model, import the developed model to Huawei HiLens, compile the logic code, and create a skill based on the customized algorithm model and logic code. If your algorithm model does not meet the format requirements of Huawei HiLens, you can use the model conversion function.

Deploying Skills	Deploy skills on devices to facilitate debugging.	Installing and Debugging Skills
Viewing Skill Performance	View the device data and how the skills have been performing.	Managing Data

Manufacturers Manage Products

Huawei HiLens provides a product management process for manufacturers who produce cameras that run HiSilicon Hi35xx series chips. With Huawei HiLens, the manufacturers can manage devices, purchase skills, and distribute licenses to devices so that all of the devices can have AI capabilities.

Figure 3 shows the product management procedure, and Table 3 describes the procedure in detail.

Purchasing Skills	Purchase required skills (used for HiSilicon Hi35xx series chips) from the skill market and distribute them to user devices.	Purchasing Skills
Distributing Skills	Distribute the purchased skills to devices, download corresponding SDKs, and integrate the SDKs to the devices for users to use.	Distributing Skills

Huawei HiLens Function Overview

**Table 4** Function overview
Chapter	User Role	Description
Registering an Account	All	Create a Huawei Cloud account. Through this account, you can have access to all Huawei Cloud services and pay only for the services you use. Before using Huawei HiLens, you also need to obtain the authorization of related services.
Registering HiLens Kit Devices	Common users Developers	Before using or developing skills, you need to purchase devices and connect them to the Huawei HiLens console on the cloud. For details, see the operation guide provided.
Managing Devices	Common users Developers	You can manage registered HiLens Kit devices on the Huawei HiLens console, including skill management, firmware upgrade, and camera configuration. Go to the Device Management page to see your device management options (both users and developers).
Developing Skills	Developers	You can create skills on the Huawei HiLens platform by developing and combining algorithms, models, and logic code, or by using preset skill templates. In addition, you can debug a newly developed skill on a test device. Then, you can release the skills that have been debugged to the skill market for more users to use. In return, you will get the appropriate amount of reward.
Skill Market	All	The skill market is an open platform that provides skills tailor-made for different chips and application scenarios. You can purchase skills in the skill market. If you are a developer, you can release your skills to the skill market and get paid.
Managing Data	Common users Developers	You can view the video data of devices registered with Huawei HiLens to see how skills perform.
Managing Products	Manufacturers	Manufacturers of devices that run HiSilicon Hi35xx series chips can use the Huawei HiLens platform to manage products, purchase the needed skills, distribute the skills to devices, download SDKs, and integrate the SDKs to the devices to enable them with AI capabilities.
