It is customary for conference posters to contain at least preliminary results. However, feedback and suggestions with regards to the experimental design – a major benefit of poster sessions – would be most helpful before data collection has started. In hopes of achieving this, we will be hosting a pre-data collection poster session.

Receiving feedback at this early stage promotes rigorous and impactful science – researchers can identify confounds, hidden assumptions, or other concerns that would likely be raised by reviewers. This cuts down research waste as suggested changes can be implemented before resources are committed. Researchers may even learn of similar studies and potential issues, helpful resources, or opportunities for collaborations between labs. This mirrors Registered Reports, an Open Science initiative, where peer review of a pre-registration occurs before data is collected.

Interested VSS attendees will be asked to sign up by indicating their research topic and a short (250 word) description of their research idea and preliminary design. Registration for this event will be just-in-time (deadline: May 1). Those selected will be asked to prepare a conference poster which focuses on the theoretical background of the study and their proposed study methods. There will be a maximum of 40 posters, and spots will be granted on a first come, first serve basis.

We are aware that, under an adversarial, competitive view of academia, this event may place presenters in a vulnerable position – participation publicizes research ideas without allowing them to formally lay claim through a publication. We encourage poster viewers to be mindful, using this event to establish collaboration with presenters and improve science. We will be creating an Open Science Framework Meetings page if presenters wish to upload their pre-data posters, providing a verification and timestamp of their research proposals. However, ultimately if you are worried about getting scooped, presenting your idea at this event might not be the right decision for you.

If you want to present a poster on your proposed research design, you can submit your abstract using this Google Form. If you merely want to browse and comment on the posters, no registration is necessary.

Update May 2nd: Submissions are still open, but please send us a note () to make sure that we process your submission promptly.

Update May 16th: Please find the abstract booklet here:

The human eye contains five distinct classes of photoreceptors: the short, medium, and long-wavelength cones, the rods, and the intrinsically Photosensitive Retinal Ganglion Cells (iPRGCs). Although each type is maximally activated by a unique wavelength of light, their spectral sensitivity bandwidths overlap, so that most light sources will activate multiple photoreceptor types. Therefore, researchers who wish to functionally isolate a given receptor type will use the “silent substitution” technique, in which pairs of light are used to selectively modulate the activity of a target photoreceptor type while maintaining a static level of activity in the other photoreceptor types.

However, conventional displays, with RGB primaries alone, are often insufficient for producing the spectral outputs, or light pairs, required for most “silent substitution” applications. In principle, it is necessary to have as many primaries as receptor types that you wish to target or “silence,” with carefully selected spectral profiles.

In this presentation, we will discuss how we designed a 4-primary “multispectral” projector (PROPixx) that can modulate activity (spatially and temporally) in one class of receptors while “silencing” three other receptor types, such as targeting rods while silencing the three cone types. We will review the technical challenges involved in building projectors with 4+ primaries, and the computational modeling approaches we took in selecting primaries for different silent substitution applications. We will also expand on other vision science applications that can be achieved with multispectral displays.

Finally, our guest speaker, Dr. Pablo Barrionuevo (Justus-Liebig Universität Giessen, CONICET-UNT), will highlight how he and his collaborators have used the multispectral PROPixx in their research.

LGBTQ students are disproportionately likely to drop out of science early. Potential causes include the lack of visible role models and the absence of a strong community. This social event is one small step towards filling that gap and will bring awareness to continuing challenges for queer scientists.

Please join us towards the end of the opening night reception, in the Garden Court (located between the Jacaranda building and the Grand Palm Colonade).

All are welcome. Snacks, drinks, and camaraderie will be provided.

WorldViz VR will give an educational seminar and hands-on demonstration of the latest virtual reality and mixed reality consumer devices with built in eye tracking and will explain how this equipment can be used in a research context. This presentation will include a high level overview of virtual reality and mixed reality key concepts as well as explanations for how to create custom immersive experiments using the latest software, including a demonstration of the SightLab VR Pro drag-and-drop VR + eye tracking toolkit. WorldViz VR will also provide examples of notable publications and successful use cases for virtual reality + eye tracking research across various academic disciplines. Participants will walk away with a better understanding of currently available immersive technology and how they can use it in their own research – they may be surprised how easy it is.

The past decade has seen a resurgence in conversation between vision science and philosophy of perception on questions of fundamental interest to both fields, such as: What do we see? What is seeing for? What makes seeing different from remembering, deciding or imagining? The phiVis workshop is a forum for continuing and expanding this interdisciplinary conversation. Short talks by philosophers of perception that engage with the latest research in vision science will be followed by discussion with a slate of vision scientists.

Conversations between philosophers of vision and vision scientists have enriched research programs in both fields. On the one hand, the latest generation of philosophers of vision are deeply immersed in the scientific literatures on natural scene statistics, visual short-term memory, ensemble perception, contour integration, amodal completion, visual salience, multi-sensory integration, visual adaptation, and much else. On the other hand, vision scientists have found a great deal of value in responding to and thinking together with philosophers about the mechanisms and effects of perceptual constancies, attentional selection, object perception, and perceptual uncertainty, to name just a handful of topics. These conversations are not only intrinsically interesting for everyone involved, they have been fruitful sources of research and collaboration. However, opportunities for dialogue are all too rare, often occurring only through chance interactions or one-off workshops. The phiVis satellite is meant to be a platform to extend these discussions.

There will be an informal reception at the Demo Night BBQ, the evening before the workshop, with a couple of tables and wine. All are welcome to stop by!
