The ubiquity of high speed, low latency cellular data plans makes remote control of desktop applications via mobile devices a feasible reality. However, user desktop interfaces designed for navigation using a high resolution pointer, such as a track pad or mouse, are very cumbersome to manipulate via a mobile device. Newer mobile devices typically have high-resolution touch screen displays, many of which match or surpass the resolution of their desktop counterparts. The problem therein is that human fingers are not getting smaller. Fingers in front of the screen block the view of the screen and obscure what users are trying to touch. Additionally, finger grime can dirty the screen and cause scratching. These problems are magnified when trying to remotely control desktop applications from mobile devices, using various remote protocols such as Remote Desktop and VNC.
One embodiment of the present invention provides a system for using a mobile device to remotely control a desktop application that was configured for use with a pointing device. During operation, the system receives at a mobile device, from a user, a connection request to connect to a desktop application executing on a remote device. In response to the connection request, the system establishes a remote control session between the mobile device and the remote device. Next, the system receives, at the mobile device, a video stream from a first camera coupled to the mobile device. The system then analyzes the video stream, at the mobile device, to identify a gesture made by the user. Next, the system identifies, at the mobile device, a pointing device command corresponding to the gesture. Finally, the system sends the pointing device command to the desktop application executing on the remote device.
In some embodiments of the present invention, the system receives, at the mobile device, a second video stream from a second camera coupled to the mobile device. Next, the system analyzes the second video stream to identify a second gesture made by the user. The system then identifies a second pointing device command corresponding to the second gesture. Finally, the system sends the second pointing device command to the desktop application executing on the remote device.
In some embodiments of the present invention, the second camera is coupled to a same side of the mobile device as a main display.
In some embodiments of the present invention, identifying the second gesture involves identifying a motion of one of an eye or an eyelid.
In some embodiments of the present invention, the first camera is coupled to an opposite side of the mobile device from a main display.
In some embodiments of the present invention, identifying the gesture involves identifying a motion of a hand.
In some embodiments of the present invention, identifying the gesture involves identifying a motion of a marker.
In some embodiments of the present invention, analyzing the video stream involves using hardware within the mobile device that is optimized for determining motion vectors.
In some embodiments of the present invention, the system receives a selection from the user of an object in the video stream. The system then uses a focus lock feature of the mobile device to focus on the object.
In some embodiments of the present invention, the system uses an accelerometer coupled to the mobile device to compensate for a motion of the mobile device while the video stream is being received.
In some embodiments of the present invention, the mobile device is a wearable device.

Thus, the present invention is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The data structures and code described in this detailed description are typically stored on a non-transitory computer-readable storage medium, which may be any device or medium that can store code and/or data for use by a computer system. The non-transitory computer-readable storage medium includes, but is not limited to, volatile memory, non-volatile memory, magnetic and optical storage devices such as disk drives, magnetic tape, CDs (compact discs), DVDs (digital versatile discs or digital video discs), or other media capable of storing code and/or data now known or later developed. Note that the term “non-transitory computer-readable storage medium” comprises all computer-readable media, with the sole exception of a propagating electromagnetic signal.
The methods and processes described in the detailed description section can be embodied as code and/or data, which can be stored on a non-transitory computer-readable storage medium as described above. When a computer system reads and executes the code and/or data stored on the non-transitory computer-readable storage medium, the computer system performs the methods and processes embodied as data structures and code and stored within the non-transitory computer-readable storage medium.
Furthermore, the methods and processes described below can be included in hardware modules. For example, the hardware modules can include, but are not limited to, application-specific integrated circuit (ASIC) chips, field-programmable gate arrays (FPGAs), and other programmable-logic devices now known or later developed. When the hardware modules are activated, the hardware modules perform the methods and processes included within the hardware modules.
One embodiment of the present invention provides a system for using a mobile device to remotely control a desktop application that was configured for use with a pointing device. During operation, the system receives at a mobile device, from a user, a connection request to connect to a desktop application executing on a remote device. For example, the user may be connecting to her desktop computer from her mobile smartphone via the Virtual Network Computing (VNC) protocol. In response to the connection request, the system establishes a remote control session between the mobile device and the remote device.
Next, the system receives, at the mobile device, a video stream from a first camera coupled to the mobile device. Note that a majority of modern smartphones incorporate at least a rear-facing camera for picture and video recording; and many also include a front-facing camera for video conferencing. The system then analyzes the video stream, at the mobile device, to identify a gesture made by the user. For example, this gesture could be a simple hand movement or a finger movement. Next, the system identifies, at the mobile device, a pointing device command corresponding to the gesture. This command can comprise any command made with a traditional high-resolution pointing device, such as a mouse, track pad, or track ball, including: moving a cursor, making a selection, scrolling a window, etc. Finally, the system sends the pointing device command to the desktop application executing on the remote device.
In some embodiments of the present invention, the system receives, at the mobile device, a second video stream from a second camera coupled to the mobile device. As mentioned previously, many modern smartphones incorporate two cameras, one on the front and one on the back of the device. Next, the system analyzes the second video stream to identify a second gesture made by the user. The system then identifies a second pointing device command corresponding to the second gesture. Finally, the system sends the second pointing device command to the desktop application executing on the remote device.
In some embodiments of the present invention, identifying the second gesture involves identifying a motion of one of an eye or an eyelid. For example, the system may use the first camera, which is coupled to the opposite side of the mobile device from the main display, to track the user's hand motions to move the cursor on the remote device while simultaneously using the second camera, which is coupled to the same side of the mobile device as the main display, to track the user's eyelids for blinking to indicate right and left mouse clicks.
In some embodiments of the present invention, identifying the gesture involves identifying a motion of a hand, while in some embodiments of the present invention, identifying the gesture involves identifying a motion of a marker. Note that the marker may be any type of object that is easily recognized by the system. In some embodiments, the marker includes physical markings to aid in identification of the marker.
In some embodiments of the present invention, analyzing the video stream involves using hardware within the mobile device that is optimized for determining motion vectors. Note that many modern smartphones have specialized hardware for video encoding that is efficient at determining motion vectors. For example, many modern smartphones incorporate video encoding hardware, such as dedicated H.264 encoding chips, as well as hardware optimized for handling software encoding routines. Newer smartphones even have the encoding hardware incorporated directly into the CPU or GPU. These encoding mechanisms typically operate by quickly determining motion vectors from one frame to the next. Embodiments of the present invention may leverage this hardware to implement the system with minimal impact on system resources, including processor cycles and battery power.
In some embodiments of the present invention, the system receives a selection from the user of an object in the video stream. The system then uses a focus lock feature of the mobile device to focus on the object. Many smartphones include focus lock features that are hardware and/or software enabled to aid in taking photographs and videos. Embodiments of the present invention can leverage this focus lock feature to aid in analyzing the gestures.
In some embodiments of the present invention, the system uses an accelerometer coupled to the mobile device to compensate for a motion of the mobile device while the video stream is being received. Most modern smartphones and mobile devices include a number of accelerometers for various functions. Embodiments of the present invention may leverage these accelerometers to negate the motion introduced into the video stream caused by moving the mobile device.
In some embodiments of the present invention, the mobile device is a wearable device. For example, a pair of glasses with at least one camera and an embedded screen may be used with embodiments of the present invention.
