The present invention is related to a system and method of acquisition, registration and multimedia management. Being part of the multimedia devices area, the present invention is useful to be applied in contexts where there is a need to record activities of manual detailing, in a professional or recreational scope, and in which recording is beneficial to the dissemination of art. Emphasis can be made in areas such as medicine, education, civilian security, military, engineering and craft activities. The present invention is thus useful for creating new methods of recording, managing and teaching tools.
In the prior art, there are known to exist systems for the acquisition, registration and/or multimedia management, which can be used at a professional or recreational level. Multimedia systems comprising glasses (also known as smart glasses) are already known, such as the ones described in US2016/0286115, WO2014/197109, US2015/0009309 and CN203551883.
Most of these systems include smart glasses with a built-in image capture camera, which may be specific for developing certain functionalities, and a transmitter which transmits the acquired images to a projection device.
US2016/0286115 discloses a multimedia system comprising a camera that captures images from your front field of view, means for transmitting such images to the monitor of a mobile device, which are displayed in a part or window of said monitor and an element that aligns the camera with its frontal field of view, in a manner independent of the angular position of the mobile device or the head or eye of the user, by implementing a counterweight, or some active mechanism. It also mentions the integration of an audio system having an earphones or speakers. Further, it is also not disclosed the form of automatic command, or given by the user, for the camera to start or end capturing images, to focus on the object of interest. In addition, it is disclosed the use of a fisheye type lens and selection of a part of the screen for recording. This choice has the limitation of a resulting variable resolution with the distance to the centre of the image, meaning not all regions of the recorded image are useful for recording details, instead of using a motor. In short, this document only discloses a conceptual device, i.e. does not disclose how these elements are integrated in the device and how to overcome the technical difficulties underlying the manufacture of such glasses, namely regarding the accuracy of the captured images for use in medical field, such as a laparoscopic surgery, the interaction between the surgeon and the sterilized device, etc. In addition, this system provides images captured by a camera to a screen and therefore, the user only sees the displayed images. This unables the disclosed system to be used in the same way of the one of the present invention since the user sees through the screen of the device.
Document WO2014/197109 discloses glasses that project infrared images on a transparent display screen comprising a stereoscopic video camera device including at least two chambers each preferably capturing infrared images from a surrounding environment and a projection system projecting: (i) a first infrared image on a transparent part of the field of view of the left eye, and (ii) a second image on a transparent part of the field of view of the right eye. These glasses allow the user to see the surrounding environment in low light conditions, such as night vision, while maintaining natural vision. For this purpose, cameras that can be aligned through a manual or electromechanical adjustment system are proposed, in order to change the convergence or divergence of the two chambers and thereby provide a three-dimensional effect of varying depth when projecting the images captured on the screens' transparent viewfinder, with an effect that is analogous to the movement of the eyes as they move towards objects at different distances. However, no vertical adjustment for capturing images is mentioned. Also, no mechanism for voice control is provided. Therefore, this system is quite different from the one of the invention and cannot be used for the same purpose.
US2014/221785 (Google Tec. Holdings LLC) discloses a messaging device, which can be smart glasses, that by detection of hand or finger gesture enters in a social media mode, authenticating the user and then converting a spoken message into a social media text message. Therefore, said device comprises a gesture sensing mechanism, a microphone, an application for converting the voice message into text message presented on a display. Said document does not disclose an adjustable video camera controlled by voice for acquisition of multimedia data. Again, the device is quite different from the one of the present invention and cannot be used for the same purpose.
US2013/437854 (GoPro Inc.) discloses a system and a process that generates 3D-images for a video from 2D-images from at least two cameras. Said system only shares with the device of the present invention the feature of being smart glasses having a camera.
Multimedia systems comprising glasses that can be used for medical purposes are disclosed in the documents WO2016/195401 A1, WO2016/190607 A1 and WO2016/182090 A1.
The document WO2016/195401 A1 discloses a system comprising an optical-based Head Mounted Display (HMD) and a set of at least three sensors mounted on the surface or inside of the body of a patient that transmit data to the HMD wirelessly. The HMD is incorporated into glasses which may provide assistance to physicians during surgeries, overlapping the surgeon view of the patient body with the 3D data acquired with the set of sensors.
The document WO2016/190607 A1 discloses a multimedia system comprising glasses with an image display device, an image processing module, a camera for capturing images, a communication unit for transmitting the acquired image to the image processing module, a spectroscopy module in the near infrared (near infrared—NIR) and a communication module for transmitting the image captured by NIR to the image processing module. This system generates images with fluorescence thus allowing the surgeon to superimpose fluorescent images of the area that is being subjected to the operation, in real time, and thus allowing to verify the development of pathologies in real time while performing the surgery.
The document WO2016/182090 discloses a multimedia system comprising a glasses-type terminal, an imaging display unit, a photographic camera, a sensor unit for capturing the user's eyes with respect to the external environment, and a control unit for analysing the user's eyes in order to specify an object.
Nowadays, the most functional multimedia glasses or smart glasses, in terms of image acquisition flexibility, ease of interaction with the user, data transmission and autonomy, are those marketed by Pivothead®. These comprise a video camera located on the nasal bridge, with fixed point of view. The interaction between the user and the device is made by touch and the status indication through LEDs located on the rear face of the glasses frame.
None of these multimedia glasses known in the art tries to actively change the cameras' point of view to match the user's point of view making adjustments in response to the users' voice and allowing to record with precision and accuracy the work performed therein.
The automatic recognition of different recording modes to suit the user's needs, such as a hand recording mode and landscape mode, is also not provided by said smart glasses of the art.
Also, none of the multimedia glasses known in the prior art has a censorship mechanism that detects faces and covers them up in real-time, before the record is made.
In another aspect, none of the existing devices has a mechanism that allows real-time signalling of the area of footage or point of view area.
Additionally, none of the prior art multimedia glasses responds to user's voice or gesture commands to allow adjustments on the point of view of the camera, beginning, stopping, and restarting motion picture capture, still image capture (photography) or adding bookmarks, etc.
Accordingly, it is desirable to develop a system and method of acquisition, registration and management of multimedia data, which may be used in a professional or recreational environment.
The present invention relates to a system and method of acquisition, registration and multimedia management.
The multimedia system of the present invention comprises a data acquisition module, preferably multimedia glasses, also called smart glasses, for multimedia data acquisition, a computerized module, comprising a data processing unit, for controlling the functions, recording, storing, managing and/or sharing multimedia data acquired and, at least, one connection module for connecting the data acquisition module to the computerized module and sharing, transmitting and/or streaming multimedia data.
Optionally, the multimedia system may further comprise a multimedia data processing module for storing, recording, processing, editing, managing, sharing, transmitting and/or streaming multimedia data and, at least, one additional connection module to connect to a data acquisition module and/or to a computerized module.
The multimedia system of the present invention may further comprise a multimedia data library.
Thus, in a first aspect, the present invention relates to a system of acquisition, registration and multimedia management, according to claim 1.
The use of a data acquisition module (A), a multimedia glasses, with the capacity to change the cameras' point of view to match the user's point of view, in association with a delocalized computerized module (B), with better performance and autonomy when compared with the existing alternatives that integrate the processing and energy storage in the glasses frame, allows highly differentiated multimedia records, supported by higher processing power and autonomy. These records can be then edited, managed, catalogued and stored in a multimedia data processing module (D), leading to better ease of access and consultation of such records and to the creation of an individual and shareable media library.
These glasses that can be operated without a touch interface and with an adjustable point of view provide greater versatility to this device allowing it to have an adequate response to the different demands of the environment. The preferential use of a lighting device as a signalling mechanism of the filming area allows demarcation of the recording area involved.
To allow more functionalities and autonomy without compromising ergonomics, all the computational load and energy storage are done outside the glasses' frame where more volume is available.
The present invention further relates to a multimedia system comprising a data processing module (D) according to claim 2, capable of storing a multimedia library (ML), and/or comprising at least one peripheral device (P), according to claim 3.
The use of a multimedia data processing module, embedded in a computer for instances, enables to do the management, storage and sharing of data on a large scale, with greater ease and better performance than the processing unit.
The existence of a multimedia library allows the user to customize and to have quick and easy access to the stored contents, which are tagged and catalogued in a personalized way.
Finally, the present invention further relates with a method of acquisition, registration and multimedia management, according to claim 15.
The method of acquisition and recording of multimedia data of the present invention allows to capture images from a certain point of view, which can be dynamic, matching with the user's point of view, giving it greater accuracy to the registrations made and minimizing the unintentional loss of multimedia information. In addition, this data can be optionally directed to a computerized module that comprises a data processing unit, for controlling the functions, recording, storing, managing and/or sharing of multimedia data acquired, and/or to a multimedia data processing module, which can allow them to be selectively and objectively stored, managed, edited and shared.

In this example, the multimedia system of the invention comprises a smart glasses unit as data acquisition module (A) as shown in
With the data acquisition module (A) mounted on the head, the user can:
During a laparoscopy procedure, the area of interest that is effectively registered has to contain the laparoscopy monitor (P). The borders of the image may be darkened or completely eliminated using a digital zoom that only contains the monitor (P).
The computer vision algorithm, via inertial sensor, may still help censoring areas with sensible data, for example faces, when the user relaxes his neck muscles and unintentionally changes the point of view of the camera.
When recording in environments that contain sensible data, as it is the case of the present example, the user must end the recording with a voice command using a predefined and personalised activation code or expression, followed by the proper command that indicates the intention to end the recording.
In this example, the multimedia system comprises the same modules as mentioned above.
With the data acquisition module (A) placed on the head, the user can:
In this operating pre-set mode, it is possible that there are faces in the recording area of the camera. When this happens, the facial detection algorithm will censor them, to protect the privacy of those involved in the surgery and the staff on the operating room. To finish the recording, the surgeon can issue a voice command with a predefined and personalised activation code or expression followed by the command to stop the recording.
With the glasses placed on the user's head, the user can:
The user can have feedback on the area that is focused by looking at the screen located in the computerized module (B) or by acknowledging the area illuminated by the lighting mechanism.
The user should end his recording using a voice command, a predefined and personalised activation sentence followed by the command, or by using the touchscreen interface.
The user can wirelessly transmit content while recording by:
The video processing software (
The user begins by authenticating with a password and ideally, with a two-factor authentication using a code received in his mobile phone. If used by a doctor to record medical surgeries, with the card reader, the user can also authenticate with his medical certificate.
With the computerized module (B) connected to the multimedia data processing module (D), the user can, after authentication:
A wearable head mounted device comprising a glasses frame (
6.1: Module A has a camera located in the nasal bridge mounted in a rotatable platform (6).
6.2: Module A has an LED light mounted on the same platform (6) as the camera, to illuminate its field of view and give a feedback to the user on the area that is being recorded.
6.3: Module A has a motorized (8) system behind the platform on which the camera and light are mounted, to rotate it vertically and horizontally.
6.4: Module A has an optical mechanism to change the focusing angle of the light from the LED and to zoom in and out the field of view of the camera.
6.5: Module A has a status LED (5) mounted in the front face of the body of the frame, to the left or right ends, to give feedback to other people on the recording status of the device.
6.6: Module A has a bone conducting transducer (BCT) positioned in the back side of the right arm of the frame (2), behind the right ear, making contact with the mastoid process of the temporal bone. This frees the external auditory canal, while retaining the privacy not achievable using regular speakers. With this mechanism, while using this device, there is no interference with the communication inside the operating room.
6.7: Module A has a microphone mounted to the right or left of the camera, LED and motor assembly, so that the user can record audio and give voice commands to the device.
6.8: Module A has an inertial sensor positioned in the front, next to the microphone, to detect the inclination of the glasses frame, and consequently the inclination of the user's head.
6.9: Module A has protections lenses (10, 11) in front of the eyes of the user. If the user needs eyesight correction, these lenses include it in themselves.
6.10: Module A has anti-fog lenses mounted behind the protection lenses.
6.11: Module B has a touchscreen that the user can use to interact with the device, defining settings, start and stop recording, previewing, etc.
6.12: Module B has a battery that powers all the systems of the device, for up to 12 hours.
6.13: Module B has a processing unit responsible for the storage and processing of the recorded media and controlling the many hardware subsystems of the device.
6.14: Module B can connect to other devices using Wi-Fi networks and/or using Bluetooth technology, in order to stream the media being record.
Having the same general features as described in Example 6, the device is powered by an electric cable that is connected to module B and to a power source such as an electrical plug or generator, indefinitely extending the normal autonomy of the device, as long as power is available at the source.
Having the same description as in Example 6, the processing unit of module B is moved to module A to one of the arms of the frame, the touch screen of module B is discarded, and the two cables, one exiting from each arm of the frame, now only carry power from a battery, located now where module B was before, allowing for a lighter and smaller module B, and lighter and thinner cables exiting from the frame of the device.
Having the same general features as described in Example 8, the battery is substituted by another power source such as an electrical plug or generator, indefinitely extending the normal autonomy of the device, as long as power is available at the source, eliminating the need of the module B completely.
Having the same general features as described in Example 6, the microphone is positioned near the mouth, mounted on an adjustable and detachable beam, allowing for better quality voice capture for recording and recognition, but with the disadvantage of being incompatible with some kinds of masks and other facial protections the user may be required to use.
Having the same general features as described in Example 6, the BCT is replaced with an earphone, to adjust to situations where a free auditory canal isn't critical in the user's work.
Having the same general features as described in Example 6, the optical mechanism is non-existent, so the focusing angle of the light of the LED is fixed and any camera zoom operation is done digitally.
Having the same general features as described in Example 6, any eyesight correction is to be employed with the anti-fog lenses, instead of the protection lenses.
Having the same general features as described in Example 6, the motorized system behind the camera and led platform, can only rotate the platform vertically.
have Horizontal Motorization of the Camera and LED Platform Having the same general features as described in Example 6, the motorized system behind the camera and led platform, can only rotate the platform horizontally.
