DESCRIPTION

DEVICE FOR IDENTIFICATION OF OBJECTS BY A TABLET OR SIMILAR

OBJECT OF THE INVENTION

The purpose of this invention application is to record the device for object identification by means of a tablet or the like, which incorporates notable innovations and advantages over the techniques used up to now.

More specifically, the invention proposes the development of a device for identifying objects by means of a tablet or the like, which, due to its particular layout, makes it possible to very advantageously facilitate the identification of objects from a tablet or other electronic device with a screen.

BACKGROUND OF THE INVENTION

It is known in the current state of the art the use of emerging technologies such as augmented reality, through mobile devices such as tablets or cell phones or the like, which has allowed users to interact with a physical environment by combining virtual and real elements. This is achieved through the use of the cameras of the devices that serve to track markers on objects (QR codes, in general) that have been designed for interaction.

This technology has become popular, among many other fields, in the educational field, due to the multiple recreational benefits it entails, such as learning based on discovery, books with augmented performance, games with augmented performance or skill training ( Yuen, Yaoyuneyong, & Johnson, 2011).

However, the way in which users interact with this technology complicates the task, since in addition to having to hold the mobile device with their hands, they need to manipulate the objects that are intended to be tracked with the camera. A problem that becomes more complex when we talk about children.

The popularity with which the uses of electronic devices such as smartphones or tablets have diversified has grown rapidly. More and more applications have user interfaces built through multi-touch systems.

However, with the appearance and implementation of applications that make use of emerging technologies such as augmented reality, many users, especially children, may have problems when interacting with these devices and the objects necessary to make use of this technology.

Devices comprising a support system for mobile devices such as digital tablets are known in the state of the art. However, they have drawbacks in the versatility of the opening angle they have in relation to the horizontal plane, since their proposal is more oriented towards providing greater height to the device and thus being able to have greater spatial coverage on the work surface.

Other devices solve this situation to some extent. However, his approach is more geared towards a system of devices including a camera, a detector, and a physical work surface. This work surface does not have any object that allows knowing what the limitations of the physical space in terms of the camera's vision on the surface. This is extremely important since, if one takes into account that the direct users of the proposed product are children, they will have little idea of the spatial limits in which they can move tangible objects.

On the other hand, progress can be seen in how to improve interaction with an object on a surface, in other devices where a lighting system is incorporated as a head that is supported on the base to hold the screens and directs its light towards the base surface to work, generating space-object interaction systems. It is a fairly expensive solution, but it also responds to design-oriented design solutions for specific applications or games.

The present invention contributes to solving and solving the present problem, since it allows very advantageously to facilitate an identification of objects from a tablet or other electronic device with a screen
