Abstract: A system, device, application stored on non-transitory memory, and method can be configured to help a user of a device locate and pick up objects around them. Embodiments can be configured to help vision-impaired users find, locate, and pickup objects near them. Embodiments can be configured so that such functionality is provided locally via a single device so the device is able to provide assistance and hand guidance without a connection to the internet, a network, or another device (e.g. a remote server, a cloud based server, a server connectable to the device via an application programming interface, API, etc.).
