20170270415
The present disclosure generally pertains to electronic devices, systems, and methods for a knowledge- and/or skill-adaptive provision of information.
When browsing or searching the Internet, all users typically get the same data presented in the same fashion. On the one hand, this is a wanted characteristic of a free and open Internet, on the other hand, in particular for those browsing the Internet for e.g. gathering information on a certain topic, a generalized way of providing and representing information can lead to inefficiency as the user's to personal interests, needs, prior knowledge and/or skills are not considered, requiring him/her to identify the desired or suited information themselves.
Thus, it is generally desirable to provide improved electronic devices, systems, and methods for providing user-adaptive information.
According to a first aspect, the disclosure provides an electronic device comprising: circuitry configured to: obtain information representing a person's knowledge and/or skills; update a user model representing the person's knowledge and/or skills based on the obtained information; and provide user-adaptive information depending on the user model.
According to a further aspect, the disclosure provides a system comprising: one or more collectors for obtaining information representing a person's knowledge and/or skills; a storage comprising a user model representing the person's knowledge and/or skills based on the obtained information; and an information provider for providing user-adaptive information depending on the user model.
According to a still further aspect, the disclosure provides a method comprising: obtaining information representing a person's knowledge and/or skills; updating a user model representing the person's knowledge and/or skills based on the obtained information; and providing user-adaptive information depending on the user model.
Further aspects are set forth in the dependent claims, the following description and the drawings.
Embodiments are explained by way of example with respect to the accompanying drawings, in which:
Considering a user's knowledge and/or skills may significantly increase the effectiveness and value of a personalized recommendation or information provision system.
Accordingly, in the embodiments described below in more detail an electronic device is disclosed comprising circuitry configured to: obtain information representing a person's knowledge and/or skills; update a user model representing the person's knowledge and/or skills based on the obtained information; and provide user-adaptive information depending on the user model.
An electronic device may for example be a PC, or a mobile device such as a mobile phone, a smartphone, a wearable, or the like. Circuitry of the electronic device may comprise processing circuitry such as a processor, or the like.
Information representing knowledge may for example be any piece of information representing theoretic information obtainable by a person, e.g. a person's knowledge about smartphones and their usage.
Information representing skills may for example describe a person's capability to perform a certain practical task of a specific domain, e.g. the task of cooking a specific meal, the task of practicing a specific sport, or the task of playing a specific game. Hence, a skill may be understood as a person's ability to utilize certain information related to a specific domain in practice.
Information representing a person's knowledge and/or skills may be stored in a user model. Such a user model may for example be stored in a database. A user model may comprise information that as a whole or in parts represents a person's knowledge and/or skills in specific domains. A user model may also be denoted as user profile.
The user modelling itself may be user specific. That is the information stored in a user model is typically associated with a single person, e.g. the user of an electronic device. A user model may not only represent knowledge and/or skills. It may also represent a person's interests.
In an electronic device of the embodiments, obtaining information representing a person's knowledge and/or skills may comprise determining a domain of knowledge and/or skills.
A domain of knowledge and/or skills could e.g. be “Mountainbiking” (skill) or “Electrical Engineering” (knowledge).
Collectors may be capable of automatically determining a domain by e.g. using a camera, etc. For example a collector may use images captured by a camera and image matching technologies to determine that a user is cooking, or that a user is playing tennis. Alternatively a domain may be determined on a central server or in a cloud platform, e.g. based on the data representing a person's knowledge and/or skills.
A domain may also be inseparably linked to a collector (e.g. smart tennis racket or car).
A domain may further include a number of sub-domains. For example the domain “Mountainbiking” may comprise the sub-domains “Uphill”, “Downhill”, or the like.
In an electronic device of the embodiments, the circuitry may be configured to obtain the information representing a person's information gathering and skills from one or more data collectors. A collector may for example be used to monitor a person's information gathering and skills in practice. For example, a data collector may monitor a person's information gathering.
A data collector may be a device or system which is equipped with sensors or means to gather information used to feed and improve the user's knowledge and skill model. Examples arc a computer, a smartphone, a car or a tennis racket with integrated acceleration sensors etc. or a combination of such devices. A collector may also comprise a computer used to browse the Internet with an agent that monitors a person's usage of the computer. A collector may also be software that is arranged to collect data.
An exemplifying usage of the electronic device relates to a person's gathering of information via RSS newsfeeds. If a person maintains multiple RSS subscriptions, repeated coverage of a certain topic may lead to a high redundancy in information provision. In such a case, an electronic device may hide pieces of information the person presumably already knows. This may result in an increased efficiency of the person's information gathering.
In an electronic device of the embodiments, a data collector may obtain information representing the level of the person's attention during information gathering. To this end, a data collector may for example comprise means for monitoring eye-movements, means for monitoring the time when information is gathered, and/or means for monitoring body parameters such as the person's heart rate, or the like.
In an electronic device of the embodiments, a data collector may comprise one or more sensors which provide information on a person's domain-specific skills. A data collector may for example comprise one or more cameras, accelerometers, in sports gears etc.
For example, a collector may be a smart tennis racket which is equipped with acceleration and/or position sensors. A smart tennis racket may collect sensor data during a person's usage of the tennis racket, and may transmit the collected data to an electronic device, central server or cloud platform using for example the user's smartphone as a gateway. Such a smart tennis racket may be used to obtain information representing a person's knowledge and/or skills in the domain “Tennis”. The domain “Tennis” may contain subdomains such as “Acceleration” or “Impact Hardness”. The smart tennis racket may continuously measure the acceleration values of the specific player and may transmit them to a backend such as an electronic device, a central server or a cloud platform, e.g. by using the smartphone as a gateway. The backend may determine that the acceleration/impact hardness is very low for a male player of the given age. Therefore the skill assessed to the domain “Tennis”—sub-domain “Acceleration” could be “Novice”. The backend may now provide/recommend or highlight information which may make the user recognize this improvement potential once the user uses the smart tennis racket the next time.
In an electronic device according to an embodiment, a data collector may obtain information representing a person's information gathering and skills based on: displayed information content itself; how demanding displayed information is; the amount of time a person spends on gathering information; and/or the time at which the gathering of information occurred.
Analyzing the displayed/viewed information content may for example comprise a semantic analysis of the content. Determining how demanding information is may for example comprise analyzing the terminology and/or vocabulary of the content.
Determining the amount of time a person spends on gathering the information may for example comprise determining if a person spent one hour per day or per week on gathering information of a specific domain. The more time a person spends on gathering information of a specific domain, the higher will normally be the knowledge of the person about this specific domain.
Determining the time at which the gathering occurred may for example comprise determining if the gathering of information occurred yesterday or one year ago. The longer a person's gathering of information in a specific domain is ago, the lower will normally be the knowledge of the person about this specific domain. If, for example, a user model indicates that a person last dealt with the domain “Electrical Engineering” twenty years ago, then the person may be attributed the status “Not up-to-date” in this specific domain, despite that the knowledge of the person in this specific domain once was rather high.
An example of (theoretic) knowledge may be the domain “Smartphones”, sub-domain “XPhone 12”, sub-domain “Battery Runtime”. A collector may continuously monitor the user when gathering information on the Internet or offline (e.g. using a camera). Based on a semantic analysis and means such as Face and eye tracking, or by just measuring the time the user spends reading a certain news article etc., it may be determined what the user presumably knows about the “XPhone 12”. An example could be that the user has read two articles about this new “XPhone 12”. Both these articles stated that the battery lasts for 1.5 days.
In an electronic device of the embodiments, the circuitry may be configured to provide user-adaptive information by means of one or more information providers.
An information provider may be a device or system used by the user to gather information and/or to improve his skills in a certain domain or gather knowledge. An example would be a computer used to browse the Internet, an Internet browser, or the like.
Data collectors and providers may run a certain software used to extract and transmit the relevant data or to adapt presented information according the user model on the frontend side, e.g. on a PC, or on a smartphone. Such software may be provided in form of a computer program, or service running in the background on a computer, a plugin that is installed within an Internet browser, or a software agent.
Providing user-adaptive information may operate with all types of media such as text, video or audio.
If, for example, a user model indicates that the user is considered to be an expert in the “XPhone 12”, subdomain “Battery runtime”, when the user opens a new article about the “XPhone 12” and this new article also contains the information about the battery lifetime, the user's PC, mobile phone or Internet browser may automatically be configured to hide this part of the text. Vice versa it may highlight text parts which presumably are new to the user.
Both information gathering and provision may occur in the same device, for example on a PC which is equipped with an Internet browser.
In an electronic device of the embodiments, providing user-adaptive information depending on a user model may comprise selecting, displaying, re-arranging, highlighting, recommending, or hiding information depending on the user model. Providing user-adaptive information may for example comprise directly jumping to certain time marks in video or audio content or automatically creating video/audio or text summaries/podcasts containing information with respect to the underlying user model.
In order to personalize the providing of user-adaptive information, the available content may be analyzed. For example, a software agent or browser plugin may automatically search the content and try to determine if it is matching one of the existing domains. If this is the case, the system may modify the content before and/or while it is shown to the user. Alternatively the software agent or browser plugin may automatically provide content or recommendations to the user, which can improve the user's knowledge or skill in a certain domain.
Providing user-adaptive information may also comprise highlighting or hiding text or reducing its visibility.
Accordingly, the electronic device may provide information to people with respect to their presumed knowledge and/or skills. More precisely, the electronic device may increase the efficiency and pleasure of a user's information provision and gathering by avoiding redundancy and demanding too much or too little from a person.
For example, the electronic device may allow to monitor user activities in greater detail and to enhance the performance and scope of a recommendation or adaptive content/information provision system.
In an electronic device of the embodiments, the user model may comprise information that is specific to a certain domain of knowledge and/or skill. For example, pieces of data included in the user model may be attributed to a specific domain of knowledge and/or skill.
In an electronic device of the embodiments, the user model may consider both, the aggregation and loosing of information. Loosing information may for example relate to a person forgetting knowledge after longer periods of not making use of the knowledge.
In an electronic device of the embodiments, the circuitry may further be configured to identify a user. A means for identifying a user may be any type of sensor capable of determining unique body characteristics (fingerprint/heartbeat/voice/face etc.), typically a fingerprint sensor, a camera, and/or a microphone, or the like.
User identification may happen both, with respect to data provision and/or with respect to data collection. This may allow to attribute collected data to a specific person in order to build user models, and this may allow to personalize the provision of user-adaptive information for a specific person.
In an electronic device of the embodiments, the circuitry may be configured to communicate with a centralized server and/or with a cloud platform, the centralized server and/or cloud platform maintaining the user model.
In an electronic device of the embodiments, the circuitry may be configured to provide a user with a skill/knowledge assessment based on the obtained information representing the user's knowledge and/or skills.
For example, the system may determine a certain domain or sub-domain-specific skill or knowledge value based on the data provided by the data collectors.
For each domain and eventual sub-domain certain skill parameters may be defined. An example of a skill parameter may relate to a person's capabilities of accelerating a tennis racket. Such a skill parameter may for example be “Newbie”, “Novice”, “Beginner”, “Skilled”, “Intermediate”, “Experienced”, “Advanced”, “Senior”, “Expert”, or the like. In addition or alternatively, a skill/knowledge assessment may be represented by a number that represents a person's knowledge and/or skill.
Data collectors may be equipped with means allowing them to derive skill parameters. In addition or alternatively, a central server or a cloud platform may be configured to derive skill parameters. Data collectors may further be equipped with means allowing them to transmit collected sensor data, skill parameters or values to a central server and/or to a cloud platform.
In addition or alternatively, a central server and/or a cloud platform may be equipped with means allowing them to determine skill parameters based on sensor data obtained by data collectors.
The circuitry of the electronic device may be configured to receive skill parameters from such a central server and/or cloud platform.
Based on the measurements a system may assess a skill for the domain or sub-domain.
In the embodiments described below in more detail it is also disclosed a system comprising: one or more collectors for obtaining information representing a person's knowledge and/or skills; a storage comprising a user model representing the person's knowledge and/or skills based on the obtained information; and an information provider for providing user-adaptive information depending on the user model.
A collector of the system may be any of the collectors described above.
A storage may be any means that is configured to store information, such as a data storage device (hard disk, SSD, or the like) or data memory (SDRAM, or the like).
An information provider may comprise circuitry, e.g. a processor located in an electronic device, in a central server or in a cloud platform. An information provider may for example be a PC, an Internet browser, a software agent, or the like.
In addition or alternatively, an information provider may comprise an output device (e.g. a display, touch screen, loud speaker, or the like) that is configured to present information to a user. The output device may for example be located in an electronic device such as a PC, smartphone, or wearable.
The system may further comprise a centralized server and/or a cloud platform. The centralized server and/or the cloud platform may comprise a storage comprising a user model. Accordingly, the user modelling may be done on a centralized server and/or within a cloud platform.
The centralized server and/or the cloud system maintaining the user model may collect in Formation From the data collectors, or it may collect information From aggregator hubs related to data collectors, using e.g. an Internet or local network connection.
The embodiments also disclose a system capable of automatically identifying a user, assessing his skills and/or knowledge in a specific domain and adapting the representation of information with respect to the knowledge and/or skills assessment therefore achieving a higher degree of personalization.
The proposed system may represent a holistic approach for a smarter recommendation and information provision system which may actually ease people's lives and pointedly improves theirs knowledge and/or skills.
In the embodiments described below in more detail it is also disclosed a method comprising: obtaining information representing a person's knowledge and/or skills; updating a user model representing the person's knowledge and/or skills based on the obtained information; and providing user-adaptive information depending on the user model. A method according to the embodiments may perform any of the processes described above with regard to the described electronic device and system.
The methods may be computer-implemented methods. Thus the embodiments also disclose computer programs for performing the processes disclosed in this specification.
