Description
Nr P100566NL00 1 Wireless communication system for medical assistance
FIELD OF THE INVENTION The present invention is in the field of a wireless com- munication system for medical assistance, and a use of said wireless system for training and providing medical assis- tance, wherein assistance is typically provided over a long distance. The medical assistance is typically provided by a well trained professional to laymen that at the best have been partly trained.
BACKGROUND OF THE INVENTION The present invention is in the field of a system for medical assistance wherein assistance is typically provided over a long distance in view of a medical professional not being available on site. For instance on ships and water or airborne vessels no medical trained personnel may be present. Provision of medical care is therefore legally transferred to the captain of the ship and/or a ship’s officer. The medical responsible people obtain some basic training, typically de- livered on shore. The basic training is found to be insuffi- cient in many cases, partly in view of insufficient experi- ence with many medical cases, sometimes in view of inadequate training for the specific and often complex case, and also in view of lack of familiarity with cases which may result in mental hurdles.
However in many cases the legally responsible people for medical care do have to perform medical actions and carry out medical procedures, sometimes to prevent worse from happen- ing, sometimes to save lives, sometimes to provide accurate care, and so on. In such cases they rely on their basic training and on handbooks or the like. Apart from the fact that training and handbooks are typically outdated at least a few years, they do not provide all the information typically needed to perform the medical actions required; at the best
Nr P100566NL00 2 they provide generic information and instructions, which in- formation may be of limited relevance to the case.
In addi- tion it is quite often difficult to establish what the medi- cal disorder, disease or injury actually is, especially from handbooks or likewise the internet.
Therefore quite often there is a need to consult a medical professional.
Apart from the fact that distance, language, time zone, availability, exact knowledge of the professional, etc. are already issues to overcome, the medical professional still has to rely on spoken information, or information in writing, from the peo- ple in charge of medical care, and vice versa.
Especially when time becomes an issue a risk of wrong or inadequate treatment is significant.
In most, if not all cases, the crew of a ship has insuf- ficient medical knowledge and skills to take optimal action in the event of a medical emergency.
Therefore, it is diffi- cult to provide the best possible care for a patient in re- mote locations.
Currently, doctors on shore are contacted via satellite phone or email to help provide medical care.
How- ever, often not all relevant available medical data is col- lected by the crew and additional time will be required to get the missing information if possible at all.
As a result any decision will be made based on incomplete information.
Actions based on such decision may lead to poor quality of care, to preventable injury, and to high additional unneeded risk and costs.
In addition, a final decision by the Captain or shipowner on how to react (divert the ship (or likewise airplane) to a port, keep going, evacuate the patient using helicopter or ship and so on) is then also made based on par- tial information, resulting in unnecessary high costs for evacuation and diversion of ships (~€200k per incident) and may pose avoidable risk to the patient, the ship and its crew.
There are currently no applications available that fa-
Nr P100566NL00 3 cilitate systematic collection of better quality data or pro- vide an objective risk assessment to captains to base their decision making on.
Another issue is that the people in charge of medical care, as well as the medical professional, are typically trained in a different location and/or setting. As a conse- quence a potential risk of inconsistencies is present, which may lead to wrong diagnosis, inadequate treatment, insuffi- cient treatment, neglect of certain aspects of treatment, etc. The “system” of treatment may as a result be considered unreliable and may form a risk for the treatment of the pa- tient, such as in view of claims. Such may especially be the case for ships and vessels out at sea.
In addition communication over these long distance may be hampered by stability or insufficient capabilities of a com- munication system used, such as bandwidth, noise, disturb- ances, etc.
In principle complex and costly systems might be used to overcome some of the problems mentioned, but these are not used in practice, not even on very large ships.
Some prior art not particularly relevant to the present invention is US2017/069227 Al, WO 2017/072616 Al and Us2015/0077502 A2. US2017/069227 Al recites a system and method for providing real-time object recognition. Such is not a goal of the present invention; further recognized ob- jects are not physical reality, but a representation thereof. The recognized objects are provided as tactile or audio feed- back to a typically optically disabled user. Only one end- user is involved. WO 2017/072616 Al recites a remote assis- tance workstation for remote assistance using AR glasses, which may be regarded as a classical one-way system. The goal is to assist people when using AED’s, electrodes or metronome in case of acute medical situations. However the system is not symmetrical and there is no two-way augmentation on both
Nr P100566NL00 4 ends of the system. The users are not visible to each other. US2015/0077502 A2 recites a GUI which is in any case back- ground art to the present invention. The present invention relates to a wireless communication system for medical assistance, and a use of said wireless system for training and providing medical assistance, wherein assistance is typically provided over a long distance, which overcome one or more of the above disadvantages, without jeopardizing functionality and advantages.
SUMMARY OF THE INVENTION The present invention relates in a first aspect to a wireless communication system according to claim 1. Typi- cal steps taken are visualized in fig. 1. Steps that may be taken in case of medical emergency on board a ship are: Step 1-3: gather data on state of patient through anamne- sis, physical examination, objective measurements. Step 4: Contact Doctor on shore Step 5: Captain/Shipowner makes decision based on location of ship, estimates on duration of journey, and advice on treatment of patient and risk to patient/crew/ship by doc- tor Step 6: Patient is treated on board, ship continues, devi- ates or evacuates. The present communication system used to provide medical assistance is wireless in view of too large distances typically being present between the person in charge of providing medical care and a medical profes- sional, or in view of physical inability for a profes- sional to be present. The system is intended for providing medical assistance typically to the person in charge thereof. It is specifically noted for some jurisdictions that said assistance does not relate to non-statutory sub- Ject-matter, such as methods of treatment, surgery, ther- apy, or diagnosis, but at the most to providing infor- mation and instructions to that extend. As mentioned above
Nr P100566NL00 sald person may be regarded to be largely a layman, de- spite of some training.
In order to provide proper in- structions it has been found essential that the layman can make use of a simple device, such as a mobile phone, a
5 tablet, a smart phone, or even a (small) computer, which device is typically available.
The device should have a display in order to present optical (visual) information, such as images.
The layman is typically at a first loca- tion, that is moving from one location to another, such as on a ship far from the shore, or at a remote location, such as a remote house or village, where it is impossible or too complicated to provide medical assistance, such as by flying in a doctor, by transporting the patient to shore, and so on.
In addition means of communication are thereby inherently limited.
It is therefore important that information of a patient, such as optical information on a physical reality, such as a condition of the patient, can be made available.
The first mobile device further has a microphone for obtaining audio input at the first loca-
tion, a speaker, a display, and a transceiver, preferably a wireless transceiver.
The second mobile device is con- figured in a similar, not necessarily the same, manner.
Further the first mobile device as well as the second mo- bile device are configured to augment reality, such as com-
prises a first optical input, such as a camera.
With the camera an image can be taken from a patient.
The image can be send and thereby shared to the medical professional and displayed on a second mobile device, which is configured to augment reality, and thereby the second mobile device is comparable in characteristics and/or features with the first mobile device.
The wireless system further comprises a computing device adapted to communicate with the first mobile device and with the second mobile device, the com- puting device comprising a data processor, and
Nr P100566NL00 6 a computer program product comprising instructions for op- erating the system, the instructions causing the system to carry out the following steps; - receiving a live video stream and a live audio stream from said first mobile device, said live streams compris- ing at least one time slice with at least one frame and/or at least one audio fragment comprising visual or audio in- put characterizing a living being or at least one part thereof at said first location;
- categorizing said living being or at least one part thereof that appear in said live video stream with a com- puter vision system, and/or - categorizing said living being or at least one part thereof that appear in said live audio stream with a com-
puter audio system,
- optionally receiving further input categorizing said living being or at least one part thereof, such as at least one of an identity checker, credentials checker, a unique session identifier, ECG, blood pressure, for vital pa-
rameters, blood and urine analysis, blood oxygen level, body temperature, blood sugar level, heart rate and the results of palpation, auscultation and percussion,
- based on said categorization if considered incomplete or insufficient for final categorization requesting through said first mobile device further audio and/or video input, such as further photos, or detailed photos, possibly as- sisted by AR to indicate details to be photographed,
- making a final categorization, - optionally requesting further audio and/or video input characterizing said living being or at least one part thereof through said second mobile device,
- receiving information with the respect to said first lo- cation comprising at least one of said first location, an intended trajectory of said first location, a speed of
Nr P100566NL00 sald first location, a cargo of said first location, a time constraint of said first location, and a distance to a port, - assessing said final categorization and further audio 5 and/or video input, and said information, - providing at least one treatment, which may be regarded as an integral treatment, preferably at least three treat- ments, more preferably an order of treatments, wherein a treatment comprises a location of treatment, a time frame of treatment, a person performing said treatment, costs of said treatment, risks associated with said treatment, le- gal and practical boundary conditions of said treatment, and actions and/or absence of actions, and optionally means of transportation of said living being. The computer program product may be loaded on a single computing device, on a distributed computing device, on more than one computing devices, and combinations thereof. Legal and practical boundary conditions of said treatment may for instance relate to a cargo present on a ship or airplane, amount of available fuel, single or combined travel time, weather conditions, weather forecast, presence or absence of medical assistance, insurance requirements, accessibility of a port, e.g. in view of quarantine, and combinations thereof. The applicant has therewith developed a unique appli- cation that provides an integrated system intended to im- prove all six steps taken during a medical emergency on board a ship (or any remote location for that matter) and may combine this with an assessment of the risks and costs for evacuation or diversion of the ship or airplane based on all the available info (e.g. ship’s current location). The present system uses Artificial Intelligence (AI) and Augmented Reality (AR) to improve all six steps in this process which may include at least one of:
1. Digitalize and automate the anamnesis via AI to ensure
Nr P100566NL00 8 the right information is collected;
2. Measurements are taken and entered into the system (e.g. using OCR, AI);
3. Physical examination by doctor supported by intelligent Two-Way-AR;
4. Data from steps 1-3 are sent to doctor on shore, as- sessment is improved due to better anamnesis, clear over- view of measurements, and own examination of patient through 2-way AR. Leading to better objective and quanti- fiable data;
5. Advice of Doctor and all data about the ship (e.g. lo- cation, destination, cargo, deadlines etc) are assessed and an automated risk assessment with 3 scenario’s (i.e. divert to port, evacuate patient, stay on trajectory) is given or calculated in a risk-score; and
6. Treatment is improved through 2-way AR connection with on-shore Doctor. The present system is considered the first system that integrates potential improvements to all of the steps in this process. Besides, it includes components of AI and AR that simplify the decision making process and help to col- lect health data and to treat the patient in the best way possible. This is a large improvement compared to the cur- rent state-of-the-art in which the captain needs to call a health professional by satellite phone in order to receive medical advice. It allows the captain/ship owner to make a well-informed decision based on objective data; it allows the crew to treat a patient in the best way possible; the patient gets a better treatment, and the ship company makes a better informed decision and therefore spends less money. Potential users are shipping companies and airline companies all over the world. It is noted that the global shipping industry has 116.000 ships at sea and hundreds of
Nr P100566NL00 9 billions of dollars invested therein. Ships carry 90% of all global goods. The off-shore and remote markets may also benefit from this application (e.g. Off-shore rigs, aircraft, remote communities). Thereby the present invention provides a solution to one or more of the above mentioned problems.
Advantages of the present invention are detailed through- out the description.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates in a first aspect to a wireless communication system according to claim 1.
In an exemplary embodiment of the present system the computer program product comprising instructions for recognition of information in digital image data and/or digital audio data, comprising a learning phase on a data set of example digital data having known information, and computing characteristics of categories automatically from each example digital data and comparing computed charac- teristics to their known category, preferably comprising in said learning phase training a convolutional neural network comprising network parameters using said data set, more preferably in which said learning phase via deep learning each layer of said convolutional neural network is represented by a linear decomposition into basis func- tions of all filters as learned in each layer. In an em- bodiment of the computer program product said neural net- work comprise weights that are learnt using a sample da- taset, in particular said weights are learned for a whole patch at once.
The invention relates to neural networks that apply convolution to data of data sets. A set of images are an example of such data sets. Images usually have data that has a spatial coherence. The neural network applies convo- lution using a set of filters. In the art, this set needs
Nr P100566NL00 10 to be complete, or information regarding the data is needed in order to select the right filter set to start with. Here, a set of basic functions is used with which the filters are defined. It was found that the filters can be described using the set of basic functions. Furthermore or alternatively, when the fitting accuracy needs to be higher, for fitting higher order information, the basic functions can be set more accurate. In combination or al- ternatively, the basic functions can be expanded to more of the relatively standard functions. This without using knowledge of the data set.
In the recognition of categorical information as ma- chine-learned from digital image data, convolutional neu- ral networks are an important modern tool. “Recognition of categorical information” in this sentence means to say that a label (for example “cow”, “refrigerator”, “birthday party”, or any other category attached to a digital pic- ture; the category may refer to an object in the digital image or it may refer to a condition in the scene). Thus, in fact, data that comprises locally coherent data can be binned. Often, such bins are discrete, like the label or category example above. It is also possible to categorise the data in multidimensional bins. Examples are for in- stance “small-medium-large” to an object. In fact, the network can even categorize on the basis of information that is continuous, for instance a continuous variable like size. In such a categorisation, regression analysis is possible. In this respect, data that comprises locally coherency relates to data that can be multi-dimensional.
This data in at least one dimension has data points that are coherent in an area around at least one of its data points. Examples of such data are images, video (which has position coherence and time coherence), speech data, time
Nr P100566NL00 11 series.
Data points hold some information on their neigh- bouring data points.
Purpose This is the purpose of recognition: to automatically label a yet-unseen image from features and characteristics com- puted from the digital image alone.
Learning and application phases The process of recognition of categorical information con- sists of two steps: a learning phase and an application phase.
In the processing of the learning phase, unique characteristics of categories are derived automatically from the features computed from each example digital image and compared to its known category (i.e. a stack of digi- tal pictures each labelled “cow”, a stack of digital pic- tures each labelled “refrigerator”, etc. for all catego- ries involved). These characteristics derived from fea- tures are transferred to the application phase.
In the processing of the application phase, the same features are computed from an unknown image.
By computation on the fea- tures again, it is established whether these features in- clude the unique characteristics of a category A.
If so, the unknown image is automatically labelled with this cat- egory A.
Introduction to the new approach Convolutional neural network learning can be seen as a se- ries of transformations of representations of the original data.
Images, as well as signals in general, are special in that they demonstrate spatial coherence, being the cor- relation of the value of a pixel with the values in the pixel’s neighbourhood almost everywhere. (Only at the side of steep edges it remains undecided whether a pixel be- longs to one side or to the other.
The steepness of cam- era-recorded edges is limited by the bandwidth, as a con- sequence of which the steepest edges will not occur in
Nr P100566NL00 12 practice.) When looking at the intermediate layers of con- volutional neural networks, the learned image filters are spatially coherent themselves, not only for the first lay- ers [Mallat] but also for all but the last, fully-con- nected layers, although there is nothing in the network itself which forces the filters into spatial coherence.
See figure 1, for an illustration of intermediate layers.
Approach Different from standard convolutional neural nets we pre- program the layers of the network with Gaussian-shaped filters to decompose the image as a linear decomposition onto a local (Taylor- or Hermite-) functional expansion.
The invention further relates to a method for recognition of information in digital image data, said method compris- ing a learning phase on a data set of example digital im- ages having known information, and characteristics of cat- egories are computed automatically from each example digi- tal image and compared to its known category, said method comprises training a convolutional neural network compris- ing network parameters using said data set, in which via deep learning each layer of said convoluticnal neural net- work is represented by a linear decomposition of all fil- ters as learned in each layer into basis functions.
In an exemplary embodiment of the present system the computer program further comprising instructions for - at least once sub-categorizing said living being or at least one part thereof that appear in said live video stream with a computer vision system, and/or - at least once sub-categorizing said living being or at least one part thereof that appear in said live audio stream with a computer audio system, - optionally receiving further input sub-categorizing said living being or at least one part thereof, such as at least one of an identity checker, credentials checker, a
Nr P100566NL00 13 unique session identifier, ECG, blood pressure, for vital pa- rameters, blood and urine analysis, blood oxygen level, body temperature, blood sugar level, heart rate and the results of palpation, auscultation and percussion.
- based on said sub-categorization if considered incom- plete or insufficient for final sub-categorization re- questing through said first mobile device further audio and/or video input, - making a final sub-categorization, - optionally requesting further audio and/or video input characterizing said living being or at least one part thereof through said second mobile device, and - receiving information with the respect to said location comprising at least one of said first location, an in- tended trajectory of said first location, a speed of said first location, a cargo of said first location, a time constraint of said first location, and a distance to a port, - assessing said final categorization and further audio and/or video input, and said information.
In an exemplary embodiment of the present system cate- gories and sub-categories are selected from living being dis- eases, living being disorders, living being injuries, living being illnesses, living being mental illnesses, living being injuries, categories not-requiring treatment, and combina- tions thereof.
In an exemplary embodiment of the present system said first location is a ship or an airplane, and wherein said port is a harbour of an airport, respectively.
In an exemplary embodiment of the present system said person performing said treatment is a captain, a pilot, or a crew member.
In an exemplary embodiment of the present system said location of treatment is selected from the first location,
Nr P100566NL00 14 and a further location, such as a port.
In an exemplary embodiment of the present system a time frame of treatment is selected from direct, within 30 minutes, within 1, 2, 4 or 12 hours, within 1 day, within 3 days, within 10 days, within 30 days, or after 30 days.
In an exemplary embodiment of the present system in actions and/or absence of actions are selected from admin- istration of medication, surgery, application of medical supports, such as gauzes, or a combination thereof, and/or wherein means of transportation of said living being is selected from a helicopter, a ship, or a combination thereof.
In an exemplary embodiment of the present system costs of said treatment include treatment costs, costs of trans- portation, commercial costs in view of ship or airplane movements.
In an exemplary embodiment of the present system said further audio and/or video input characterizing said liv- ing being or at least one part thereof relate to physical examination, measurement of a body parameter, anamnesis, impression of well-being of said living being, or a combi- nation thereof.
In an exemplary embodiment of the present system the computer program product comprises instructions for receiving augment reality input from the first or second mobile device, and instructions for transmitting augment reality output to the first or second mobile device.
Therewith, based on AI, augmented reality can be provided on the first or second mo- bile device respectively, such as a visual indication on where to perform treatment or part thereof, such as by high- lighting an area of the living bean, such as by highlighting with a green (positive) or red (negative) colour.
In an exemplary embodiment of the present system both devices have implemented a two-directional transmitting
Nr P100566NL00 15 system, wherein the transmitting system in use receives at least one layer of first optical input from the first de- vice relating to a physical reality from the first device and transmits the at least one layer of first optical input to the second mobile device and receives at least one layer of second optical input relating to a physical reality from the second device from the second optical input and transmits the at least one layer of second optical input to the first mobile device. In addition thereto the first device in use displays second optical input of the second device super- imposed over the first optical input, and wherein the sec- ond device in use displays first optical input of the first device subimposed over the second optical input, and wherein the displayed input on the first device is prefer- ably equal or partly equal to the displayed input on the second device, that is the combined or merged inputs, ei- ther superimposed or subimposed, are equal to one and an- other. It is noted that the terms “superimposed” and “sub- imposed” are relative and in principle are considered in- terchangeable as long as the various layers of input are projected over one and another in a usable fashion. There- with both devices are provided with at least one layer of augmented reality superimposed over an image representing reality at the first or second location, respectively.
Therewith effectively the use of a first device and the user of the second device look at the same image, or at least part thereof; in other words the displayed images on the first and second devices respectively are the same, though the full display need not be used for displaying sald images. The image may be displayed together with at least one further image, or not. The medical professional now can give input to the layman, such as directions, ad- vice, can provide medical details, etc. which input can be

SUMMARY OF THE FIGURES Figure 1 shows schematics of the prior art and fig.2 of the present invention.
DETAILED DESCRIPTION OF THE FIGURES Figure 1 shows schematics of the prior art.
Figure 1 describes the current situation: In a remote location, such as a ship, when there is a patient a layperson like a ship's officer, will have to: - Take an anamnesis (1), ask questions and might base these on a book, form or likewise; - Take medical measurements (2), like blood pressure, heartrate and so on. Usually without no recent and often any training; = Do a physical examination (3), like checking out chest and abdomen by doing palpations, auscultation and so on. Again with little or no prior training; - The combined (1+2+3) information will be communicated with a doctor onshore by email, radio, or satellite tele- phone. The doctor will make a clinical decision and tries to make a diagnosis and will give advice on a treatment (4); - Based on the doctors diagnosis and advice the captain or the shipping company will make a decision on what to do with the logistic part of the treatment, like diverting the ship (5). Step 4 and 5 are usually not taken in coor- dination; - Finally the on board treatment of the patient needs to
Nr P100566NL00 20 be carried out by the layperson/ship’s officer (6). Usu- ally he/she has to work form memory, any past training and a book and perform procedures like giving injections, set- up IV drips and so on.
Figure 2 describes the situation us- ing the system:
In a remote location, such as a ship when there is a pa- tient a layperson like a ship’s officer, will have to: - Take an anamnesis (1) supported by using a mobile device with AI that will ask the right questions, go in detail where needed, and can might interact directly with the patient or the caretaker.
This leads to a relevant, accurate, detailed, and digitally stored anamnesis;
- Take measurements (2), like blood pressure, heartrate, and so on.
Using the 2-Way-AR functionality via a mobile de-
vice the doctor or onshore expert can guide, instruct, and coach the layperson in real time and ‘hands-on’ on what he/she exactly to do to take the measurement.
This way the quality of the measurements taken can be assessed and im- proved by giving visual guidance;
= Do a physical examination (3), like checking out chest, and abdomen by doing palpations, auscultation and so on.
Us- ing the 2-Way-AR functionality on a mobile device the doctor or onshore expert can guide, instruct and coach the layperson in real time and ‘hands-on’ on what he/she exactly to do to do a good examination.
This way the quality of the physical examination can be assessed, the patients response to it taken into account and the execution and quality of the exam- ination can be improved by giving visual guidance, instruc- tions and coaching;
- The combined (1+2+3) information gathered will be of sub- stantial higher quality and give the expert/doctor better in- formation to base his/her diagnosis on (4). For that reason it will be more accurate;
- This likely diagnosis and the medical treatment will now
Nr P100566NL00 21 be combined with other relevant data (like location, direc- tion, speed, cargo, sailing distances to nearby ports, weather, cargo and so on) from the ship (4-5). Using AI and based on relevant data the system will present the captain and/or shipping company with treatment options to optimize the outcome for the patient, taking the ship’s safety, risks involved and costs into account (5); - Finally the on board treatment of the patient needs to be carried out by the layperson/ship’s officer (6). Using the 2- Way-AR functionality on a mobile device the doctor or onshore expert can guide, instruct and coach the layperson in real time and ‘hands-on’ on what he/she exactly to do to when treating the patient.
All medical procedures can be supported and supervised.
Working as a team the layman and the expert can carry out on board treatment in a safe and successful way.
This way the quality of the treatment can be assessed and improved by giving visual guidance; - All steps (1-6) can be digitized and can, with the ap- proval of parties involved, also be used to improve future care and learn from outcomes. - The system will improve remote medical care by improving various aspects, such as by adding 2-Way-AR and AI, and sup- port decision making.
EXAMPLES /EXPERIMENTS The invention although described in detailed explana- tory context may be best understood in conjunction with the accompanying examples.
Practical example Step by Step instructions on using AR system for remote medi- cal support The example relates to a situation wherein Device 1 is on a remote location and Device 2 is a device on medical support location (doctor's device). Additional devices may be pre- sent, in so far as required and feasible and it may relate to
Nr P100566NL00 22 any additional unit. It is the combination of devices (mini- mum two: device 1 and 2) that may be regarded as the present basic system.
In order to start the (both) devices should be powered up, meet minimum technical specifications, use a compatible software platform (Android/i0S/Windows/Linux etc.), have ad- ditional drivers and software installed for two-directional transmitting, be connected to the internet and/or have an IP address. When using the present AR-application/platform the two devices should connect, identify and use a secure connec- tion.
The following steps are typically performed. 1) The person(s) using device 1 (hereafter: helper, typi- cally a layman) and the person(s) using device 2 (hereafter: the medical professional, typically a doctor) and the patient or object (hereafter: the subject) can be positively identi- fied by voice, vision, available ID or any other legal or re- quired means.
2) If possible they agree to: their role and accept terms and conditions of use by 1) signing in with known and veri- fied credentials of by 2) direct input (typing, touching, clicking) or clearly stating verbally and the patient/object responsible for accepting and consenting to the help offered. 3) Device 1 may be positioned either: - static, using a fixing device that will hold device 1 in place, - or dynamic, by being attached to the helper in their line of sight, using goggles or any other means to comfortably at- tach the device, — or is positioned in such a way relative to subject, that the helper can work, manipulate and use instruments/tools on the subject, while keeping the subject in view/on screen of the device.
4) Device 2 may be positioned either:
Nr P100566NL00 23 - static, using a fixing device that will hold device 2 in place, — or dynamic, by being attached to professional in their line of sight, using goggles or any other means to comfortably at- tach the device, — or is positioned in such a way, that the professional can work, manipulate and use instruments/tools in front device while keeping the subject on screen of the device. 5) A calibration sticker can (but does not need to) be used: it has a unique session number, a colour calibration print and a fixed size for reference and will be placed close or next to the subject within the vision frame of device 1 (cam- era) and device 2 can calibrate after detection of the sticker. 6) By using device 2 the professional can in so far as re- quired: - make drawings, display pictures, project video(s) using de- vice 2 as input device, by touching the screen, or using any input device (mouse, stylus, touchpad, controller, etc.) or retrieving pictures, images and video material from a data- base or any other source - manipulate his hands, arms and any other part of his body, such as to indicate to the helper to perform certain actions, manipulate instruments of tools in such manner that the cam- era of device 2 captures these movements, pictures or projec- tions, such as to provide a visual example. 7) These inputs created by the professional using device 2 can be projected on device 1 (and likewise device 2) onto an overlaying visual layer that results in a projection of the reality (the actual view of the subject, relating to a physi- cal reality) with the visual (AR) layer (relating to at least one of a further physical reality, images, graphics, pic- tures, etc.) superimposed on the screen of device 1. The
Nr P100566NL00 24 helper will see both the subject as well as the (superim- posed) input made by professional on device 2. 8) By using device 1, the helper can see the subject (in re- ality and on screen), see directly what professional shows, explains, and/or instructs him to do (in AR overlay), see pictures, images, supporting information from database or any other source (in AR overlay), see video’s on how to carry out certain skills and techniques (in AR overlay), can switch the AR layer on- and off on device 1, can see and train and pre- pare for copying and re-doing the manipulations and instruc- tions shown by professional, and can execute or perform the manipulations, instructions or skills shown in the AR layer in reality on the subject.
9) The professional can see the subject, see the AR overlay as visible on device 1, including any visual input used, see any actions by helper, give directions and instructions to the helper, using voice, text, video and/or AR overlay, and can switch the AR layer on and off on device 1 and 2.
10) All actions on device 1 and 2 are logged and saved in a database.
In view of operation additional functionality may be added. For instance device 1 can have sensors attached, that will help to monitor the condition of subject. In case of a patient ECG, heartrate, blood pressure and other vital param- eters can be monitored and made visible on device 1 and 2. The helper can use device 1 without a professional (no device 2) and using images, video's, explanations on skills and techniques retrieved from a database or any other source, that can be superimposed (via AR layer) on the subject. Using artificial intelligence and machine learning, the collected input from the database can be used to recognize, diagnose certain conditions and predict any required actions to be taken by helper.
