News editors obtained the following quote from the background information supplied by the inventors: "The present invention deals with a man machine interface capable of sending commands to electronic devices. More specifically, it allows provisional transformation of different types of smart mobile devices, which have not been specifically designed for this purpose, into a specific device that can be used exactly like an air mouse and/or a remote control, taking also advantage of the ergonomics that are more and more common on said smart mobile devices.
"Smart mobile devices include personal digital assistants, smart phones, specifically i-Phones.TM., and also i-Touch.TM., i-Pad.TM. and possibly some other multimedia storage and reproduction devices. These devices typically now include motion sensors (accelerometers and possibly gyroscopes and/or magnetometers), positioning sensors (GPS receiver), a digital camera, a Bluetooth and/or a Wifi link, a touch screen, a local processing power, etc. . . . The use of such devices by professionals, and the general public at large, has become very widespread and usage is very intensive. Users typically always carry their smart mobile device with them. By downloading a code on said device from an application store, they can have access to a quasi-infinite quantity of applications and content. Some of these applications take advantage of the motion and/or position capture potential of the smart mobile device but, to date, they have not gone as far as allowing the users of these smart mobile devices to get rid of other devices that they need to use for specific purposes, like an external mouse to replace the touch pad mouse of their portable computer, so that they are able to avoid carrying such a mouse with them, in addition to their smart mobile device. Also, while at home, the same professional has to use at least one other interface with his TV studio (and it is more likely that he will have to use at least two, one for the TV itself, another one for the set-top box). All these interfaces have their own weight, power consumption, ergonomics, software configurations, vendors, etc. . . . A PC mouse, which is generally used on a desk surface, cannot be used with a TV set and a TV remote control, which is generally moved in free space, cannot be used with a PC.
"There is therefore a need for a universal man machine interface, which can be used as a remote command of all kind of electronic apparatuses, which would use all the possibilities offered by smart mobile devices. Some devices have been developed to this effect, but they fail to achieve integrated surface and free space control modes. They also fail to take full advantage of the capabilities of the current sensors and new features now available on smart mobile devices. The instant invention overcomes these limitations."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "To this effect, the present invention provides a handheld device comprising at least one motion sensor and a touch screen, said device being capable of communicating signals from said sensor to a host device comprising a motion signals processing capability, wherein said touch screen of said handheld device comprises a number of touch zones which are operative to control at least an application running on said host device with movements of said handheld device on a surface or in free space, at the option of the user.
"The invention also provides a method and a computer program to use said handheld device.
"In a preferred embodiment, the smart mobile device comprises at least a two axes gyroscope, which allows precise pointing, recognition of the gestures of the user. In various embodiments, the touch zones emulate the usual buttons of a mouse (left, right, scroll wheel). More specifically, the scroll wheel is made to be emulated by a zone which may extend to the whole surface of the touch screen. Also, one of the touch zones can be used to transform the 2D mouse into a 3D mouse or remote control with the capability to directly control the movements of a cursor on the display of the host device or to send information on the gestures effected by the user of the handheld device which are then interpreted by the host device as commands of a number of preset functions. Furthermore, the touch zones on the screen of the handheld device can be made dependent on the application running in the foreground of the host device, which provides a lot of versatility to the device of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
