Locative Art – Application Interface Personal Work

Application: Layar
Type: iPhone interface
Scope: Illustrations

Software used: Illustrator, InDesign, Photoshop.

The Locative Art application will be specially designed for the iPhone but will technically also work with other smartphones using the android system, the layar application is currently used for displaying the art the interface therefore refers to and matches the original layar interface. The technique behind the art pieces comes from what is also known as augmented reality, Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.

The application icon was designed to achieve a recognizable image, working in the different sizes required for any application for the iPhone, iPod touch or iPad. The first created art piece by the author was used for shaping the apps logo, a stylized view of the painting “The Sea of Ice” (1823-24) by Caspar David Friedrich. This being the start of the locative art project remains the logo for all later digitally constructed 3d models placed inside the augmented reality. The word ART is stressed in order to categorize the app while directly detaching it from other augmented reality programs, which are mainly used for commercial reasons, locative being just the additive, remaining readable in the sub line.

There are certain requirements for a smartphone in order to work with augmented reality, one being a GPS-device integrated into the phone, in order to get the location coordinates, another being the compass, to find out the direction the user is looking at. The camera inside the phone is recording what is seen in front of the person, while the accelerometer is telling the program how the phone is orientated in the real world.

An internet connection is needed to download the model and data from the server while uploading feedback from the phone. A gyroscope, being another device for measuring the orientation, is an optional further requirement, meaning it is not actually necessary but can be useful for a smoother experience. The iPhone 4 has a gyroscope installed. Perspective calculation programs exist also right now but would be just a further addition to get a better positioning feedback from the integrated camera and would only needed to be included into the software directly without any additional phone requirements.

The interface uses the same colour palette as defined in the graphic design for the corporate identity. Next to the title you find the publishers name and a short description accompanied with a project icon, which will be visible throughout the whole use of the interface. The information screen delivers also a more detailed description of the project and a screenshot of what you are about to experience. In the live response mode you find a radar guiding you to the different points of interest while a live feedback shows you the projects location in your camera view.

Through the main camera you can actually experience the locative art in its context while walking around it seeing it from different perspectives. The map view helps users to orientate themselves according to the locative art piece with the radar in the top right corner and your own positioning on the map as the targets location. In the zoom icon you can find an enlarged top view of the project.

In addition to the camera view there is also the optional satellite view using google’s satellite imagery to locate yourself and the art in its urban context with an additional scale showing your altitude from the viewing perspective. The elevation will be further on necessary while viewing the installation, whereas the GPS-coordinates only refer to a two-axial location in space some art pieces have to be view from a specific elevation in order to gain the full experience.

The iPad will become of more importance in the future, based on it’s larger display, which will make it more interesting for the 3d experience. Although at the time there aren’t too many people walking around with an iPad under their arm and therefore the concentration on smartphones seems more reasonable, the application works as well and on iPhones as on iPads., or any other tablet PCs.

During the experience the user has actually the chance to take snapshots of the art piece while walking around it as to watch the 3d object separately on screen. This will be also interesting for potential buyers for whom the locative art can be additionally coded for their own environment to experience. The images represented here are three-dimensional images best being viewed with anaglyphic red/cyan glasses; this is only necessary for illustration purposes of the three-dimensional experience.
