IQ-Wall at Indiana University

System overview

The IQ-Wall is an original design by the UITS Advanced Visualization Lab at Indiana University that tiles very thin, energy-efficient flat-screen monitors into configurations that meet the resolution requirements of users and their physical environments. IQ-Walls are driven by a single Windows computer and feature a low barrier to entry. The AVL has integrated several IQ-Walls, but the premier unit is located in the lobby of the Cyberinfrastructure Building and features 24 tiles and nearly 50 million pixels.

System access

Access to all visualization systems is physical (i.e., you must be in the room with the device to use it). At this time, no remote access or virtual desktop support is available. To request physical access to visualization devices, email the AVL. An AVL staff member will be assigned to you; that person will meet with you to discuss your project and proposed usage scenario. Once your use is approved, your assigned AVL staff member will provide an orientation and proper training to get you started using the system. Most visualization systems have 24/7 access via keycards. Calendaring and scheduling options will be discussed during your orientation.

Computing environment

All visualization systems are on the IU ADS domain, so you authenticate using your IU Network ID. This means your desktop is your own environment. By default, you will not receive administrative privileges. If you feel you need administrative privileges, you should discuss it with your AVL contact.

Development and running applications

The AVL provides a variety of APIs and software frameworks appropriate for a wide variety of visualization-related tasks. No one solution will work for every situation. During your orientation you can discuss your specific visualization needs with your AVL contact, who can direct you to the most appropriate software and, if needed, help you download and install new or custom software.

Working with data

All visualization systems have local storage areas, but they are not backed up and are purged regularly. Before each working session, you must import all data and program files from a long-term storage medium, and transfer them back to long-term storage when you're finished. All visualization systems have USB support and are connected to the IU network, so you can use long-term storage media, such as USB (flash or magnetic) drives, and network-enabled storage services, such as the IU Scholarly Data Archive (SDA).

Support

Direct all questions to your assigned AVL contact, or email the AVL.
