## Abstract

Remote access to the user interface of a mobile computer is carried out by simultaneous use of the screen broadcast function and the data reception functionality of the interface of peripheral input devices of this mobile computer to interact with a remote control computer via an IP network. Routing of mobile computer screen broadcast streams to the control computer can be carried out on a local network, e.g., through DHCP or mDNS (DNS-SD) services, and relaying to other networks through an appropriate proxy server. The conversion of IP manipulation data coming from the control computer to the mobile computer interface is carried out using a gateway with IP and HID interfaces. The invention can be implemented both on the basis of one device with Bluetooth HID or USB HID options, and on the basis of a local network of a mobile computer containing routers and gateways with appropriate properties.

## Claims

### Claim 1

An access device to a user interface of a mobile computer configured as a smartphone, the access device comprising:
a wireless Wi-Fi interface connected to a local network and configured to:
receive via the local network and transmit via the local network to any other computer network of screen broadcast data representing a broadcast of the screen of the mobile computer to a controlling computer, and
receive Internet Protocol (IP) format data corresponding to a manipulation of an interface of peripheral input devices of the mobile computer from the controlling computer;
a proxy server application for relaying the screen broadcast data representing the broadcast of the screen of the mobile computer to the controlling computer to other networks;
a conversion gateway application for converting the IP format data corresponding to the manipulation of the interface of the peripheral input devices of the mobile computer arriving from the controlling computer into a Human Interface Device (HID) format data compatible with the interface of the peripheral input devices of the mobile computer, the conversion gateway application containing:
an IP interface connected to a computer network for obtaining the IP format data corresponding to a manipulation of a peripheral input device of the mobile computer from the controlling computer; and
an HID interface for direct connection, via a Bluetooth interface of the access device, with a Bluetooth interface of the mobile computer;
wherein, after conversion of the IP format data into the HID format compatible with the interface of the peripheral input devices of the mobile computer, the HID interface of the access device transfers, via the Bluetooth interface of the access device, to the Bluetooth interface of the mobile computer, the HID format data representing the manipulation of the peripheral input device of the mobile computer from the controlling computer; and
wherein, after the mobile computer receives, via the Bluetooth interface of the mobile computer and from the Bluetooth interface of the access device, the HID format data representing the manipulation of the peripheral input device of the mobile computer from the controlling computer, the peripheral input device of the mobile computer performs, without requiring an application additionally installed on the mobile computer, an action corresponding to the manipulation of the peripheral input device of the mobile computer from the controlling computer.

### Claim 2 (depends on 1)

The access device according to claim 1, wherein the access device is implemented as a computer of any type.

### Claim 3 (depends on 2)

The access device according to claim 2, wherein the access device includes at least one of USB and Bluetooth interfaces.

### Claim 4 (depends on 2)

The access device according to claim 2, wherein the access is implemented as a second smartphone.

### Claim 5 (depends on 2)

The access device according to claim 2, wherein the access device contains an operating system of any type.

### Claim 6 (depends on 2)

The access device according to claim 2, wherein the access device is configured for use as a user interface access device.
