The natural language processing system 312 may analyze captured audio data and visual data to determine portions of the interface of the kiosk that may need improvement or cause difficulty to some users. In some embodiments, the natural language processing system 312 may include a natural language processor 314, data sources 328, a rank notifier 326, profile module 332, and a sentiment ranker module 330.
The natural language processor 314 may be a computer module that analyzes the captured audio data and visual data of the user interaction with the kiosk. The natural language processor 314 may perform various methods and techniques for analyzing documents containing audio data converted to text (e.g., syntactic analysis, semantic analysis, etc.). The natural language processor 314 may be configured to recognize and analyze any number of natural languages. In some embodiments, the natural language processor 314 may parse passages of the documents or portion of a recorded conversation or interaction of the user with the kiosk. Further, the natural language processor 314 may include various modules to perform analyses of the captured audio and visual data. These modules may include, but are not limited to, a tokenizer 316, a part-of-speech (POS) tagger 318, a semantic relationship identifier 320, a syntactic relationship identifier 322, profile module 332, and sentiment analyzer 324.
In some embodiments, the tokenizer 316 may be a computer module that performs lexical analysis. The tokenizer 316 may convert a sequence of characters into a sequence of tokens. A token may be a string of characters included in an electronic document and categorized as a meaningful symbol. Further, in some embodiments, the tokenizer 316 may identify word boundaries in an electronic document and break any text passages within the document into their component text elements, such as words, multiword tokens, numbers, and punctuation marks. In some embodiments, the tokenizer 316 may receive a string of characters, identify the lexemes in the string, and categorize them into tokens.
Consistent with various embodiments, the POS tagger 318 may be a computer module that marks up a word in passages to correspond to a particular part of speech. The POS tagger 318 may read a passage or other text in natural language and assign a part of speech to each word or other token. The POS tagger 318 may determine the part of speech to which a word (or other text element) corresponds based on the definition of the word and the context of the word. The context of a word may be based on its relationship with adjacent and related words in a phrase, sentence, or paragraph. In some embodiments, the context of a word may be dependent on one or more previously analyzed electronic documents or interactions of a user or group of users with a kiosk. Examples of parts of speech that may be assigned to words include, but are not limited to, nouns, verbs, adjectives, adverbs, and the like. Examples of other part of speech categories that POS tagger 318 may assign include, but are not limited to, comparative or superlative adverbs, wh-adverbs, conjunctions, determiners, negative particles, possessive markers, prepositions, wh-pronouns, and the like. In some embodiments, the POS tagger 318 may tag or otherwise annotate tokens of a passage with part of speech categories. In some embodiments, the POS tagger 318 may tag tokens or words of a passage to be parsed by other components of the natural language processing system 312.
In some embodiments, the semantic relationship identifier 320 may be a computer module that is configured to identify semantic relationships of recognized text elements (e.g., words, phrases) in documents or from captured audio data and paired with visual cues captured in the visual data. In some embodiments, the semantic relationship identifier 320 may determine functional dependencies between entities and other semantic relationships.
Consistent with various embodiments, the syntactic relationship identifier 322 may be a computer module that is configured to identify syntactic relationships in a passage composed of tokens. The syntactic relationship identifier 322 may determine the grammatical structure of sentences such as, for example, which groups of words are associated as phrases and which word is the subject or object of a verb. The syntactic relationship identifier 322 may conform to formal grammar.
Consistent with various embodiments, the sentiment analyzer 324 may be a computer module that is configured to identify and categorize the sentiments associated with tokens of interest. In some embodiments, the sentiment analyzer may be configured to identify, within text passages, and annotate keywords that are preselected as high quality indicators of sentiment polarity (e.g., indicators of positive sentiment could include brilliant, excellent, or fantastic). Various tools and algorithms may be used by the sentiment analyzer 324 as are known to those skilled in the art (e.g., Naïve Bayes lexical model). The quality indicators of sentiment polarity may be correlated with specific user profiles within an establishment or the profile for the establishment.
In some embodiments, the natural language processor 314 may be a computer module that may parse a document and generate corresponding data structures for one or more portions of the document or posts. For example, in response to receiving a set of posts from a website that includes a collection of posts or reviews of food products at the natural language processing system 312, the natural language processor 314 may output parsed text elements from the product reviews as data structures. In some embodiments, a parsed text element may be represented in the form of a parse tree or other graph structure. To generate the parsed text element, the natural language processor 314 may trigger computer modules 316-324.
In some embodiments, the output of the natural language processor 314 may be stored as an information corpus 329 in one or more data sources 328. In some embodiments, data sources 328 may include data warehouses, information corpora, data models, and document repositories. The information corpus 329 may enable data storage and retrieval. In some embodiments, the information corpus 329 may be a storage mechanism that houses a standardized, consistent, clean, and integrated copy of the ingested and parsed documents of the text of the audio captured. Data stored in the information corpus 329 may be structured in a way to specifically address analytic requirements. For example, the information corpus 329 may store the captured audio data and visual data based on groups of related products (e.g., products of the same type) in order to make ranking product features easier. In some embodiments, the information corpus 329 may be a relational database.
In some embodiments, the natural language processing system 312 may include a sentiment ranker module 330. The sentiment ranker module 330 may be a computer module that is configured to generate sentiment scores for specific forms of features or qualities based on the analysis of annotated reviews or posts of the food product of an establishment. The sentiment ranker module 330 may be further configured to rank the features based on these sentiment scores.
The rank notifier 326 may be a computer module that is configured to notify users of feature rankings determined by the sentiment ranker module 330. In some embodiments, the rank notifier 326 may communicate with a rank notification receiver module.
The profile module 332 may be a computer module that is configured to establish and maintain profiles of groups of users and associated problems with the interfaces of the kiosk. The profile module 332 may store feedback and the captured sentiment in relation to portions of the interface of the kiosks.
In a first step, an input indicating a user is using a kiosk device is received (step 202), for example by the user feedback program 66. The input indicating the user is using the kiosk device may be, but is not limited to, a command from a user through the user interface.
The user feedback program 66 captures audio data from the user during the user's interaction with the kiosk device (step 204). The data may be stored in a repository, for example repository 53 for analysis later or alternatively analyzed as the audio data is received. In another embodiment, only the results of the analysis could be stored.
The user feedback program 66 captures visual data of the user during the interaction with the software of the kiosk device (step 206). The data may be stored in a repository, for example repository 53 for analysis later or alternatively analyzed as the visual data is received. In another embodiment, only the results of the analysis could be stored. The visual data may include, but is not limited to, eye tracking of the user, and recordation of the user's features during the interaction with the kiosk device.
The audio and visual data stored in the repository during a user's interaction with the kiosk device is analyzed during the interaction with the kiosk device (step 208). The analysis of the audio and visual data may be used to determine a sentiment of the user during their interaction (e.g. a positive, a negative or a neutral experience). For example, sentiment analysis may be used to determine a user's emotional state during their interaction with the software of the kiosk device. Sentiment analysis is the process of computationally identifying and categorizing opinions expressed in the captured audio and visual data, especially in order to determine whether the writer's attitude towards a particular topic, product, etc., is positive, negative, or neutral.
Facial recognition may also be used with the visual data to identify a specific user of the kiosk device. The facial recognition may be integrated into the sentiment analysis. The identity of a specific user may be helpful if used in combination with user profiles, such that difficulties with specific portions or interactions with the software can be tracked based on a user's interaction to determine if specific users in a certain location, or user group may have similar problems carrying out transactions with the software of the kiosk device.
Eye tracking may additionally be determined from the visual data to determine what portion of the software the user is interacting with regardless of the actual touches or selections made by user through a screen of the kiosk device. The eye tracking may include a length of time a user spends looking at various portions of the software being displayed during their interaction with the kiosk device.
The audio data may be converted into text to leverage sentiment of the user during the transaction with the software of the kiosk device. Trigger phrases and keywords may be identified from the captured audio data and associated with specific sentiments. An overall sentiment may be determined from all of the audio data captured during a user interaction with the kiosk device.
A score of the overall user interaction with the kiosk device based on the analysis of the audio and visual data of the user interaction is determined (step 210).
Each metric of the user interaction as captured from analysis has a set of rules that map the metric to a score out of 100. For example, with facial recognition, the user could be happy, indifferent, somewhat upset or really angry. Each of these values will be assigned a score with the least frustrated being zero and the most frustrated being 100. Each metric will have a different mapping. In another example, with eye tracking, if it is determined that the user is staring at an area of the screen of the kiosk without doing anything. The score may be assigned as follows: 0-100 milliseconds=0, 101 milliseconds-500 milliseconds=10, 5 seconds to 20 seconds=50, etc. The mappings for each metric can be controlled/configured by a user experience professional responsible for the application. Once the scores are calculated for each metric averaged, producing a final score. The user experience professional can also configure the final threshold.
If the score is greater or equal to a threshold (step 212), the feedback program 66 determines at least a portion of the software may need improvement based on the audio and visual data of the user interacting with the kiosk device (step 214). The threshold may be manually set by an administrator.
The portion of the software which may need improvement or the portion of the software the user needs aid in using is sent to an administrator for further review (step 216) and the method ends.
It should be noted that in an alternate embodiment, the portion of the software that requires additional aid for use by the user may be sent to an administrator which can access the kiosk device and aid the user through the current or any additional transactions (conflict resolution) with the kiosk device or alternatively send a notification to another user associated with the kiosk device (e.g. customer service agent) to aid the user with the transactions of the kiosk device. The portion of the software which may need improvement may also be flagged for an administrator to allow the administrator to identify possible solutions or alterations of the software to increase usability.
If the score is not greater than or equal to a threshold (step 212), the score is stored in a repository associated with applicable audio and visual data as well as the software of the kiosk device (step 218) and the method ends. The data and the associated score from the user interaction with the software of the kiosk device may be sent to an administrator for further analysis to determine usability of the software and usage metrics.
In a first step, the user feedback program 66 receives data from one or more kiosk devices in a venue. The data preferably includes captured audio data from users during the user's interaction with the kiosk devices and visual data of the users during the interaction with the software of the kiosk devices (step 302).
The visual data may include, but is not limited to, eye movement captured through eye tracking of the users, and recordation of the user's facial features during the interaction with the kiosk device.
The audio data may include a user's verbal statements when present at the kiosk device.
The user feedback program analyzes the captured data (step 304).
Facial recognition analysis may be used with the visual data to identify a specific user of the kiosk device. The identity of a specific user may be helpful if used in combination with user profiles, such that difficulties with specific portions or interactions with the software can be tracked based on a user's interaction to determine if specific users in a certain location, or user group may have similar problems carrying out transactions with the software of the kiosk device.
Eye tracking may additionally be used with the visual data to determine what portion of the software the user is interacting with regardless of the actual touches or selections made by a user through a screen of the kiosk device. The eye tracking may include a length of time a user spends looking at various portions of the software being displayed during their interaction with the kiosk device.
The audio data may be converted into text to leverage sentiment of the user during the transaction with the software of the kiosk device. Trigger phrases, keywords, tone, volume and pitch may be identified from the captured audio and associated with specific sentiments. An overall sentiment may be determined from all of the audio captured during a user interaction with the kiosk device.
The user feedback program 66 determines whether a type of conflict exists for the user from the analysis of the data captured (step 306). Based on an identified conflict from the captured data, the identified conflict may be searched for in a repository or look up table. Furthermore, a set of common resolutions can be created and stored in a database that can be used by the software. This list of common resolutions would increase as user interactions increase.
For example, the type of conflict may be stored in a repository, for example repository 53. The type of conflict may be stored with an associated resolution which was at least attempted, identified sources and causes of the conflicts, user profiles that are used to or have been used to generate more realistic user personas for user interface testing; and a type of users that utilize the kiosk device and one or more types of conflict that are commonly encountered by that type of user. The conflict stored may also contain data relating to usability and summary usage metrics from the user's interaction with the software of the kiosk device.
The user feedback program 66, based on the determined type of conflict, provides to the user, one or more options that are predicted to alleviate the type of conflict (step 308) and the method ends. For example, the identified conflict may be present in a lookup table that contains a plurality of options that are predicted to alleviate the type of conflict, and selecting one or more options to present to the user based on collective user history regarding conflict resolution and a category to which the user has been determined to belong.
