LUEUR is an interactive light installation, exploring the tangible interaction with light. This work attempt to make the light becomes tangible embodied in light installation and open up new notions and interpretations into the interactive experiences of light art. We regard this work as an aesthetics approach to tangible interface design and the tangibility of light, allows us to explore installation as a form, as a prop, and as a medium for research. LUEUR provides a tangible interaction with light by creating a visuo-haptic illusion and challenging the theory of nature — light becomes tangible and receives gravity. In the experience, participants could manipulate the installation and receive the pseudo-haptic feedback caused by the dynamic visual effects of light. We implement the mechanism of the haptic sensation system as an approach to convey the different haptic sensations, providing participants a perceptual and immersive experience of light.

Who is the target audience and why design for them? The target audience of this work is people who like interactive artworks, light, interest in visiting art galleries or museums and enjoy joining the experience. We would like to encourage the viewer to actively engage with the experiencing rather than passively viewing at the work from a distance. LUEUR, the installation work as a medium, explore the tangibility of light, transport viewers’ imagination into a thought experiment, allow enough room for them to make their own interpretations. The participants become active “imaginers” who initiated the interactive experience. They could engage in the interaction and be the ones to complete the purpose of this work and to participate in its realization and further make their own interpretation of the artwork.

What were the challenges or limitations encountered in this project? During the implementation process, we thought of many styles, materials, and shapes, meanwhile, we must consider the technical performance. Otherwise, this prototype may have better quality and appealing appearance. The system needs to improve the performance for tracking the inclination and rotation which is less efficient and sensitive sometimes. In addition, while designing the pseudo-haptic feedback mechanism, the visual effects play a very important role. We have also explored many design possibilities, the visualization, and completed the entire interactive system through cross-platform integration. In order to pursue the aesthetic and efficiency performance of interaction, we must control the integration of software and hardware to provide a well experience, which is a difficult struggle for us.

What are the opportunities and next steps for this project? The potential of Lueur is not limited to what we have presented, we would also want to conduct further participants' studies to understand how participants perceive the experience and discriminate the visual modalities between the hand motion and the light display. If there are opportunities, we would like to try a more organic style or other materials to achieve the ideal appearance. As well as to improve the interactive system, make a further design to provide multiple inputs for interactivity. We vision our work will open up a new approach to realize the tangible experience of light through interactive installation, to encourage participation and inspire people into light perception.

To the Demo Visitors: We would like to gather insights and feedback on how the viewers would perceive and interpret the demonstration. It would be nice that they have any suggestions about the design and idea of this work and we would gladly receive any perspective of comments. We propose LUEUR to explore the design space of tangible interaction with the light, expand our imaginative horizons, and provide new perspectives of light. The experience is designed to make LUEUR transport participants’ imagination into a thought experiment, allowing them to make their own interpretations. Whether the viewer understands the work through experiencing the work in person or watching it through the demo, we expect that LUEUR could bring viewers a new vision, and also facilitate their imagination of the light.
