# Personalization in Digital Ecomuseums: The Case of Pros-Eleusis
## 8 Results
### Visitor Experience and Recommendations
#### 8.2.2 Proposed Improvements and Functionality  
The users also proposed future extensions for the personalized view functionality of the digital ecomuseum app. These included the following:  
**Content recommendation within the POIs**: The majority of the users felt that most POIs offered a large amount of diverse information, at times spanning across different topics, time periods, etc. Some users proposed to also apply recommendations within the content of a specific POI, allowing the users to rate specific parts of the content and, thus, the recommender system to collect more precise information about their preferences. This is an approach that needs to be further evaluated in future studies. **\"Pinning\" or demoting a POI**: Some participants proposed ways to have more control over the recommended POIs: \"I would like to be able to keep some of the recommended POIs so that the app does not make them disappear from the map\". The recommended POIs list could offer the option to keep a POI \"pinned\" for the next set of recommendations. Additionally, in case it is not interesting at all, they could choose to remove it from the list of recommended POIs, with the possibility of it appearing again later on if a significant part of the POIs have already been visited. **Explicitly show that recommended POIs change**: Some participants felt that it should be made more evident that the recommended POIs change after visiting a POI. One proposed design was to use animation to show new POIs gradually appearing while others change color or fade and gradually disappear from the map. **Highlighting the need to rate**: Two participants mentioned that they failed to rate a POI by mistake. They would have liked a confirmation of the type \"Are you sure you are not going to rate this POI?\" before moving forward. They both commented that they liked the corresponding POI and felt that if they had rated it the following recommendations could have been more accurate. **Most-recommended POI**: Some users, both during the tour and when interviewed, expressed interest in knowing what the system would propose as the most suitable POI for them to visit amongst the list of proposed POIs. They also wondered about the criteria for the specific recommendations. At the moment, there is no evident differentiation amongst the 10 recommended POIs as to which is the most highly ranked. It would be interesting to examine the effect on the user experience of highlighting this most-recommended POI or showing the ranking of all the POIs. Color coding could be used to denote differences in the recommendation strength in the manner of a heat map to differentiate highly from the moderately recommended POIs. **Nearby POIs**: There were participants that felt strongly against going back and forth when walking around to visit POIs in locations they had already passed. To this end, they suggested that it would have been useful to be able to know on demand which are the closest POIs to the one they are currently visiting, recommended or not, to avoid moving back and forth between locations. **Support for group visits**: The participants also discussed the need for the app to support group visits. As is often the case, such visits are made by a family or group of friends together. Using the app individually may result in participants having to separate to follow different routes for different POIs. Although some participants felt that one device could be used per group, and the next POI could be negotiated amongst the group, others felt that it would be more practical to use an individual device with the app. In this case, the app would need to negotiate the individual visitor profiles to identify the optimum recommendations for the whole group. **Make the options for engaging with the local community more explicit**: Most participants felt that the presentation of POIs where different types of interaction with the local community were offered was not straightforward enough.
