Title: Wobbling, drooping, bouncing—Visual perception of materials and their properties
Abstract: Visual inference of material properties like mass, compliance, elasticity or fragility is crucial to predicting and interacting with our environment. Yet, it is unclear how the brain achieves this remarkable ability. How materials move, flow, fold or deform, depends not only on their internal properties but also on many external factors. For example, the observable behavior of an elastic bouncing object depends on its elasticity but also on its initial position and velocity. Estimating elasticity requires disentangling these different contributions to the observed motion. Predicting the future path of the object requires a forward simulation given the estimated latent parameters. I will present a set of experiments in which we investigated how accurately human observers estimate the elasticity of bouncing objects or predict their future path. Furthermore, I will discuss the nature of the visual information observers use as well as the limitations of their internal model.
The Fall 2021 CBMM Research Meetings will be hosted in a hybrid format. Please see the information included below regarding attending the event either in-person or remotely via Zoom connection
Guidance for attending in-person:
MIT attendees will need to be registered via the MIT COVIDpass system to have access to MIT Building 46.
Please visit URL https://covidpass.mit.edu/ for more information regarding MIT COVIDpass.
MIT is currently welcoming visitors to attend talks in person. All visitors to the MIT campus are required to follow MIT COVID19 protocols, see URL https://now.mit.edu/policies/campus-access-and-visitors/. Specifically, visitors are required to wear a face-covering/mask while indoors and use the new MIT TIM Ticket system for accessing MIT buildings. Per MIT’s event policy, use of the Tim Tickets system is required for all indoor events; for information about this and other current MIT policies, visit MIT Now.

To access MIT Bldg. 46 with a TIM Ticket, please enter the building via the McGovern/Main Street entrance - 524 Main Street (on GPS). This entrance is equipped with a QR reader that can read the TIM Ticket. A map of the location of, and an image of, this entrance is available at URL: https://mcgovern.mit.edu/contact-us/
General TIM Ticket information:
A visitor may use a Tim Ticket to access Bldg. 46 any time between 6 a.m. and 6 p.m., M-F
A Tim Ticket is a QR code that serves as a visitor pass. A Tim Ticket, named for MIT’s mascot, Tim the Beaver, is the equivalent of giving someone your key to unlock a building door, without actually giving up your keys.
This system allows MIT to collect basic information about visitors entering MIT buildings while providing MIT hosts a convenient way to invite visitors to safely access our campus.
Information collected by the TIM Ticket:
COVID-19 vaccination status (i.e., whether fully vaccinated or exempt)
Symptom status and wellness information for the day of visit
The Tim Tickets system can be accessed by invited guests through the MIT Tim Tickets mobile application (available for iOS 13+ or Android 7+) or on the web at visitors.mit.edu.
Visitors must acknowledge and agree to terms for campus access, confirm basic contact information, and submit a brief attestation about health and vaccination status. Visitors should complete these steps at least 30 minutes before scanning into an MIT building.
