TOGO: a Contextual Tourist Mobile Guide

818 views

Published on

We present TOGO, a general model and a limited prototype of a contextual tourist mobile guide dedicated TO the city of GOrizia. Our goal is twofold: first, we offer contextual views to the users, and, second, we provide them with a personal workspace in which they can also create new, personalized paths.
In order to capture semantic interconnections among data, we use advanced data structures called zz-structures, a graph-centric system of conventions for data and computing, able to simply offer semantic modalities of navigation.

  3. 3. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkIntroduction Due to the wide diffusion of mobile systems (as tablet or smartphone), the number of tourist mobile guides is rapidly increasing (Kenteris, 2011). A recent study on U.S. Android and iOS users revealed that apps dominate mobile time spent accessing travel (95%), versus only 5% dedicated to mobile websites (Nielsen, 2012). They offer detailed information, and interesting tours related, for example, to museums, cultural heritage, shopping, attractions, services. They also share some drawbacks as i) the lack of customized and dedicated user workspaces; ii) a limited semantic navigation; iii) the lack of capability to create new tours and share them. Dattolo A., Pitassi E., Onza A., Urgolo A. TOGO: a Contextual Tourist Mobile Guide
  4. 4. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkChallenging Issues We identified five challenging aspects for an innovative mobile guide and concrete issues in the current systems: Provide personalized content and views. Enable user to author new tours. Apply semantic relations. Provide support to social aspects. Provide contextual information and navigation. Dattolo A., Pitassi E., Onza A., Urgolo A. TOGO: a Contextual Tourist Mobile Guide
  5. 5. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkRelated Work Current mobile guides of (also international) museums suffer from some limitations: Mus´e du Louvre (http://www.louvre.fr/en): this app is rich e of information and multimedia contents, but it presents navigation issues, and emphasizes disorientation. MOMA (http://www.moma.org/explore/mobile/): although this app helps the visitor with an audio support, it limits the user navigation with rigid and predefined paths of visit. AccessSights (Kr¨sche et al., 2004): subproject of o MobiDENK, this app assists tourists in a tour in the Herrenhausen Gardens, in Hannover (Germany); also for blind users, it works only inside the park. GeoNotes (Espinoza et al., 2001): tourists can retrieve notes regarding their current location and participate in the creation of the information space, but presents a main weakness: the trust of the information given by the community.

  6. 6. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkTOGO: a framework and a prototype The TOGO mobile guide: offers contextual and semantic navigation on the data; introduces user personal workspaces and manages user profiles; enables the users to create and share news paths.

  7. 7. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkThe TOGO architecture I Figure : TOGO architecture The main components of our architecture, distributed among server and mobile client, are: Model Controller View Dattolo A., Pitassi E., Onza A., Urgolo A. TOGO: a Contextual Tourist Mobile Guide
  8. 8. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkThe TOGO architecture II Model: it contains data and knowledge and a set of methods. The data is organized in two separated datasets, Knowledge Base and User Profiles. This data is aggregated and structured by: (a) the Contextual Knowledge and (b) the User Model. Controller: this component mediates between the Model and the View. It has been organized in terms of a multi-agent system, able to receive the user (and system) requests and manage them in order to carry out the appropriate actions. View: this component gives a graphical interface to the Controller and Model activities. View implements different screen panels, one for each type of content (e.g. personal user workspace, specific items of the museum - rooms, plans, collections).

  9. 9. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkThe Contextual Knowledge I The cultural heritage virtual tours, mainly based on mobile guide, suffer from a rigid navigation. In order to overcoming this issue and provide new, advanced, and contextual navigation modalities, the TOGO navigation model is based on zz-structures (Nelson, 2004, Dattolo &Luccio, 2009). Zz-structure Zz-structure is an edge-colored multigraph, subject to the following constraint: the degree of each node for a given color can assume only three possible values: 0, 1, or 2. For each color/label the multigraph presents or singletons, or linear paths, or cycles. Dattolo A., Pitassi E., Onza A., Urgolo A. TOGO: a Contextual Tourist Mobile Guide

  11. 11. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkThe Contextual Knowledge III The nodes (zz-cells) represent rooms and objects of the Coronini Museum the colored (labeled) edges define semantic relations among rooms and objects from c1 we can reach all the semantically connected information; they are identified by different colors and labels. links connect the plans of different floors, the paintings, elements visited by a specific user (a personal path), the different rooms of the museum, the furnishes, and the silverware present in it. zz-structure can be created in a flexible way: each dimension can contain one or more ranks and the logic mapping of ranks and dimensions can be interchangeably arranged.

  13. 13. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkThe zz-structure instantiation In our prototype the instantiation of the zz-structure containing our case of study is made up of the following steps: the agent zzXMLOperator pre-loads the XML Knowledge Base, organized in terms of XML file containing the ‘items’ and ‘rooms’ details (data.xml), on the mobile client; then zzXMLOperator dynamically defines the interconnections (zz-dim between items and rooms zz-cell, inquiring the XML documents containing: the collections (collection.xml), the plans (plan.xml), the personalized paths (paths.xml), the predefined tours (tour.xml), the restauration (restauration.xml).

Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkAuthoring Personal Paths Figure : authoring scenario Starting from her personal space, each user can create a personal path (‘Crea percorso/Create a path’) She chooses the ‘nome/name’, and adds all the items/rooms that she prefers (using the ‘+’ button) Dattolo A., Pitassi E., Onza A., Urgolo A. TOGO: a Contextual Tourist Mobile Guide
  17. 17. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkConclusions We presented TOGO, an innovative mobile guide which offers contextual and semantic navigation on the data and user personal workspaces. Currently, we are working on the extension of the tier-layer of our framework in order to: support user recommendation, harvest complex relationships among items, enhance social aspects. We called the new app simply Go! (for Gorizia). We would like to present now, for you, in first preview, just some features and screenshots of it in next slides.

  20. 20. Outline Introduction TOGO: a framework and a prototype Conclusions and Future WorkResearch Engine I A new feature developed for the system is the internal Research engine, that works with a special adaptive semantic algorithm based on 3 types of tags (primary, secondary and referential) and on synonyms. The algorithm provides search results referring to a list of 5581 tags and 3225 synonyms. The order of the results changes depending on previous research carried out by the user: the selected elements with greater frequency will have higher priority and will be displayed in the top of the results list.
