The next step in our project was to further elaborate the existing technology ideas and combine them with the idea of a physical library. So the question was how to make the library and our system interactive and innovative. Our first idea was to use existing technology in a innovative way. We titled these considerations as Interactive Spaces, providing several interaction techniques for visitors of the library, allowing them to gather more information about media items or in general. We combined our ideas so far to interaction concepts that can be grouped in four categories: Fixed Devices, Mobile Devices, Augmentation and Rooms.

The following sketch board gives a overview over our sketches. We also made a hybrid sketch to get a first impression about the placement of our devices.

The Information Screens are simple screens, placed all over the library providing further information. We thought about general screens, being placed at the entrance and showing actual events and news, like new books, general recommendations or highlights. The second category of information screens is topic-related, being situated near the book-shelfs they are referring to. For example, a screen providing information about actual events in Turkey beside the cardboard of guides for Turkey.

The concept of the Information Kiosk is to provide a bottom-up approach to supply additional information to the visitor about a media item he is interested in. These information could be relevant news regarding the author, prices, or event related information. Furthermore we thought about including a Rating System in the library, from which the Information Kiosk then provides user ratings as well as charts regarding the particular media item.

The Exploration Table represents the other way around of information gathering in contrast to the Information Kiosk. Here, we provide top-down information, starting with actual events and trends that can be explored by the visitors of the library and resulting in particular recommendations for physical media items from all over the library.

Regarding the mobile devices to be used in the library, we thought of usual smartphones or tablets that can be carried with by the visitors. These devices can be provided in two ways: the visitors of the library can use their personal device brought from their home, or lend it in the library for temporary use.

Using these devices, the visitors can for example take parts of the information of the exploration table and carry it away with their tablet to another place where they can read it calmly on the sofa.

To make the whole library an interactive space, we thought about augmenting the floor with arrows, either by projectors fixed on the ceiling or by projectors from mobile devices. The idea was to use these arrows in two ways

• to project for individual visitors their individual paths to the books they are looking for .
• arrows pointing on actual topics, new books or highlights of the library.

Another way of augmentation we came up with was to directly augment the books the library users take from the bookshelves. Here we thought about two different technical solutions.

The first is via projectors, recognizing when visitors take a book from the shelf and automatically projecting additional information on a white page in the book.

The second idea was via an extra device, like a kind of magic lense, revealing additional information when moved over the book.

In later discussions about the augmentation topic, we came up with the idea of augmenting a touchtable, which can be viewed in the 3D paper prototype.

Thinking about an interactive space in a bigger dimension, we developed the idea of a whole room as a place for social interaction. This Fun Room should invite visitors of the library to gather information about particular topics, for example from the touch table in the middle of the room. Then they are invited to join each other and discuss in groups, marked by the sofas in the corners, with other people having the same interests.
