Many accessibility features available on mobile platforms require applications (apps) to provide complete and accurate metadata describing user interface (UI) components. Unfortunately, many apps do not provide sufficient metadata for accessibility features to work as expected. In this paper, we explore inferring accessibility metadata for mobile apps from their pixels, as the visual interfaces often best reflect an app’s full functionality. We trained a robust, fast, memory-efficient, on-device model to detect UI elements using a dataset of 77,637 screens (from 4,068 iPhone apps) that we collected and annotated. To further improve UI detections and add semantic information, we introduced heuristics (e.g., UI grouping and ordering) and additional models (e.g., recognize UI content, state, interactivity). We built Screen Recognition to generate accessibility metadata to augment iOS VoiceOver. In a study with 9 screen reader users, we validated that our approach improves the accessibility of existing mobile apps, enabling even previously inaccessible apps to be used.

Policy maps chart LLM policy coverage over an unbounded space of model behaviors. Here, an AI practitioner is designing a policy for how an LLM should summarize violent text. Policy map abstractions (right) allow the policy designer to interactively author and test policies that govern a model’s behavior using if-then rules over concepts. The designer can create any desired concept by providing a simple text definition to capture cases of model behavior. Our Policy Projector tool (center) renders cases, concepts, and policies as visual map layers to aid iterative policy design.
Morae is an accessible user interface agent that proactively pauses automation at key decision points for blind and low-vision users to make choices. For example, when asked to “buy the cheapest sweetened sparkling water”, existing agents would automatically choose a product even if multiple items have identical prices. Instead, Morae pauses automation and presents relevant product differences (e.g., flavors, ratings) and allows users to choose based on their preferences. By proactively detecting and pausing when user input is necessary, Morae allow users to actively express preferences during UI automation.

But pedestrians navigating a landscape built for cars rightly perceive intersections as unsafe, too. On West Hudson, pedestrians who have pressed the button for a walk signal still must contend with fast-moving cars turning as they cross.

Archived clip of Vance: I realized that in this new world, I was the cultural alien. I began to think seriously about questions that had nagged at me since I was a teenager: Why has no one else from my high school made it to the Ivy League? Why are people like me so poorly represented in America’s elite institutions? Why is domestic strife so common in families like mine? Why did I think that places like Yale and Harvard were so unreachable? Why did successful people feel so different?
Dear Nest Learning Thermostat owner, ‌ Thanks for making Nest a part of your home. We truly value you as a longtime customer. We want to make you aware of some upcoming changes that will affect our earliest thermostats, including those at Bigham House. Starting October 25, 2025, Google will no longer support the Nest Learning Thermostat (1st gen) introduced in 2011 and Nest Learning Thermostat (2nd gen) launched in 2012. Over the years, we’ve brought out newer thermostats with even more ways to help you save energy and stay comfy. As part of our ongoing efforts to provide the best possible smart home experience, we are transitioning our thermostat infrastructure to a new platform offering significant advancements in performance, reliability, and features that will greatly benefit our customers. Unfortunately, we’re not able to move our older thermostats to this platform. You’ll still be able to adjust the temperature, mode, schedules, and settings on your thermostat – and existing schedules should continue to work uninterrupted. However, your thermostat will no longer receive software or security updates, will not have any Nest app or Google Home app controls, and will not support other connected features like Home/Away Assist. See more details at our support website. To help with this transition and to show our appreciation for your loyalty, we’re offering you the option to upgrade to our newest and most advanced thermostat, the Nest Learning Thermostat (4th gen), at a special price: $149.99 (MSRP $279.99).1 Please click here to redeem the offer through the Google Store (online only). Offer valid until November 21, 2025 (if you’ve already redeemed your offer, no further action is required).
Jeffrey Bigham - Thank you for agreeing to act as a committee member for CHI 2026 Papers.

First, we need to ensure workers are learning the skills employers are starting to demand. New approaches are emerging: American University’s Kogod School of Business is embedding A.I. across its curriculum and training faculty members to use A.I. tools, while Carnegie Mellon is offering an A.I. bachelor’s program in which students take classes on harnessing the power of A.I. to be “beneficial and useful for people.” Community colleges in Miami-Dade, Houston and Maricopa Community Colleges are joining in, starting a national A.I. consortium to align curriculums with work force needs and offer applied A.I. degrees backed by companies like Intel and Microsoft.

can kids register for cvpr 2025 ChatGPT said: Children are generally not permitted to attend CVPR 2025 sessions or events. While the conference offers onsite childcare services through KiddieCorp, children are not allowed in session rooms, meal functions, or on the exhibit floor. This policy aligns with previous years, where children were explicitly prohibited from these areas . CVPR 2025 +1 CVPR 2025 +1 Regarding registration, CVPR does not specify a minimum age requirement. However, participation in certain events, such as the CVPR 2025 Photorealistic Avatar Challenge, is restricted to attendees who are at least 18 years old. If an attendee is under 18 but has reached the age of majority in their legal place of residence, they may participate with parental or legal guardian consent . Microsoft For minors interested in attending the conference, it's advisable to contact the CVPR organizers directly to inquire about specific policies and obtain any necessary permissions. Additionally, if you're considering registering a child as a student attendee, ensure that they meet the eligibility criteria and that appropriate supervision arrangements are in place.
