The camera may be connected to the interaction node 1 10 via wire or wireless. In this embodiment also a feedback unit might be collocated with the objects 120 to be selected, allowing to remotely controlling the pointer from the device while providing visual feedback to the remote users via both images acquired from the camera and feedback on the device, e.g. haptic, screen information, sound etc.

[00062] In another embodiment, a second networked device 100 may further be used to select specific manifestations resulting at the device side from the digital interaction with an object. A manifestation can be defined, but not limited to, as a tuple specifying a software application on the phone and an associated resource identifier, such as an Universal Resource Identifier. For example a manifestation could consist of a specific video on YouTube that provides additional information about the object to which the device is connected. Additional fields referring to a manifestation can also be provided, including also tags, i.e. metadata specifying the type of content (see Fig. 1 1 ). The various manifestations associated to an object can be stored in a content database 310 located within an information node 300 (see Fig. 10). Upon initiating the interaction with an object 120, a device 1 10 can receive one or more manifestations of the interaction from the interaction node 100. These manifestations have been selected by the interaction node 100, considering the information available in the context database 320, among all manifestations stored in the content database 310. In the preferred embodiment, when multiple manifestations are simultaneously available, these are presented through a specific interface to the user, while when a single manifestation is instead available this is typically initiated automatically.

[00063] In another embodiment that is similar with the above embodiment the information node 300 and the interaction node 100 can be coinciding. This essentially means that both content database 310 and context database 320 can be located within the interaction node 100.

[00064] In another embodiment, a second networked device 100 may further be used to select specific manifestations at the object side that are resulting from the digital interaction with a terminal. The set of possible manifestations for an object are included in a content database that is specific for the objects 520. Depending on the type of object different types of manifestations are possible. For objects that are not connected the preferred manifestations include lighting effects performed by the feedback unit 140 and triggered by the interaction node 100. Audio and/or haptic effects with sound devices associated to the object can also be used to deliver auditory feedback in the proximity of the object. In the case of the objects being connected screens, e.g. digital signage screens, the manifestations can be defined in a similar manner as for the user devices, e.g. as couples specifying a software application on the device (typically a video player) and an associated resource identifier, or URI. For example a manifestation could consist of launching on the screen a specific video from YouTube. Additional fields referring to a manifestation can also be provided, including also tags, i.e. metadata specifying the type of content (the structure is similar to the one in Fig. 1 1 ). The various manifestations associated to an object can be stored in a content database 310 located within an information node 300. Upon initiating the interaction with an object 120, a device 1 10 can trigger one or more manifestations of the interaction. These manifestations have been selected by the interaction node 100, considering the infornnation available in the context database 320, among all manifestations stored in the content database 520.

The second handheld device 1 10:B may also be oriented at object 120:B, and may simultaneously initiate an interaction associated with the object 120:B, independently with the interaction carried out by the handheld device 1 10:A. Furthermore may the handheld device 1 10:C initiate an interaction with the object 120:C, independently of any other interactions, and potentially simultaneously with any other interactions. This is an example of where a number of devices 1 10 may be oriented at a number of objects 120. Further an example of that a number of devices 1 10 may carry out individual interactions with a single or a plurality of objects 120, simultaneously and independently of each other.

[00066] Fig. 8 illustrates the interaction node 100 and handheld device 1 10 in more detail. The interaction node 100 may comprise a spatial database 150.

[00074] In a possible embodiment it may be advantageous to collocate the functionalities of the interaction node 100 together with the functionalities of handheld device 1 10 inside the handheld device 1 10.

[00075] In a possible embodiment it may be advantageous to collocate the functionalities of the feedback unit 140 together with the functionalities of handheld device 1 10 inside the handheld device 1 10.

[00076] In a possible embodiment it may be advantageous to collocate the functionalities of handheld device 1 10 together with the functionalities of the feedback unit 140 inside the feedback unit 140.

[00077] In a possible embodiment it may be advantageous to collocate the functionalities of the interaction node 100 together with the functionalities of feedback unit 140 inside the feedback unit 140.

[00078] There are a number of advantages with the described solution. The solution may support various business applications and processes.

[00079] An advantage is that a shopping experience may be supported by the solution. A point of sale with the solution could provide shoppers with information, e.g. product sizes, colors, prices etc., while roaming through shop facilities. Shop windows could also be used by by-passers to interact with the displayed objects, gathering associated information which could be used at the moment or stored in their devices for later consultation/consumption.

[00080] An advantage in the field of marketing and advertisement, the solution may provide a new marketing channel, bridging the physical and digital

dissemination of marketing messages. By supporting digital user interactions with physical advertisement spaces, e.g. on paper billboards, banners or digital screens, users can receive additional marketing information in their terminals. This interactions, together with the actual content delivered in the terminal, can in turn be digitally shared, e.g. through social networks, effectively multiplying both the effectiveness and the reach of the initial "physical" marketing message.

[00081] An advantage may be digital shopping experience provided by the solution, transforming any surface into a "virtual" shop. By "clicking" on specific objects 120 the end users may receive coupons for specific digital or physical goods and/or directly purchase and/or receive digital goods. An example of these novel interactions could be represented by the possibility of "clicking" on a film poster displayed on a wall or displayed by a light emitting device and receiving the option of: - purchasing a digital copy of said in film to be downloaded in said user terminal, - buying movie tickets for said film in a specific theater, - reserving movie tickets for said film in a specific theater.

[00082] An advantage may be scalable control and interaction with various networked devices that is anticipated to be an important challenge for the future Internet-of-Things (loT). The solution may reduce complexity by creating a novel and intuitive user interaction with the connected devices. By pointing at specific devices, e.g. a printer, user terminals can gather network access to the complete list of actions, e.g. print a file, which could be performed by said devices, eliminating the need of complicated procedures to establish connections, download drivers etc.

[00083] An advantage may be interaction with various everyday non-connected objects that is anticipated to be an important challenge for the future Internet-of- Things (loT). The solution could reduce cost and complexity by creating a novel and intuitive user interaction with the non-connected objects. By pointing at specific non-connected objects, e.g. a toaster, the user can get access to information about the toaster manufacturer warranty and the maintenance instructions and/or add user satisfaction data.

[00084] An advantage may be interaction with objects 120 facilitated by the feedback unit 140 resulting in textual or graphical overlay on or near 120. [00085] An advantage may be the practical and cost benefits of interaction on screens and flat projections versus existing multi-touch interaction, particularly when there are multiple simultaneous users. Since the solution may use off-the- shelf LCD or plasma data display panels to provide multi user interaction, hardware costs may be lower when compared to equal size multi-touch screens or panels + multi-touch overlays. And since the solution can also use of data projection systems as well as panel displays, the physical size of the interaction space may reach up to architectural scale.

[00086] Another advantage, besides cost, for display size over existing multi- touch is that the solution may remove the restriction that the screen must be within physical reach of users. An added benefit is that even smaller displays may be placed in protective enclosures, mounted high out of harm's way, or installed in novel interaction contexts difficult or impossible for touch screens.

[00087] Another advantage may be that rich media content, especially video, may be chosen from the public display (data panel or projection) but then shown on a user's handheld device 1 10. This may avoid a single user monopolizing the public visual and/or sonic space with playback selection, making a public multi-user rich media installation much more practical.

[00088] An advantage may be interactions on the secondary screen for TV settings. A new trend, emerging in the context of content consumption in standard TVs, is represented by the so-called secondary screen interactions, i.e. exchange on mobile terminals of information which refers to content displayed on the TV screen, e.g. commenting on a social media about the content of a TV show. By adopting the solution, a series of predetermined information may be effectively and simply made available on the devices 1 10 by the content providers and/or channel broadcasters. Consider an example in which users could "click" on a specific character on the screen receiving on the mobile device information, e.g. the price and e-shop where to buy the clothes that the character is wearing, the character social media feed or social media page, information concerning other shows and movies featuring this character etc. Using the solution, content provider and broadcaster have the possibility of creating a novel content flow, which is parallel to the visual content on the TV channel, and that constitutes of novel relevant business channel on the secondary screens.

[00089] While the solution has been described with reference to specific exemplary embodiments, the description is generally only intended to illustrate the inventive concept and should not be taken as limiting the scope of the solution. For example, the terms "interaction node", "device", vicinity space and "feedback unit" have been used throughout this description, although any other corresponding nodes, functions, and/or parameters could also be used having the features and characteristics described here.
