Many Star Trek enthusiasts have pondered the possibilities of encountering a new species, swiftly teleporting out of an uncomfortable social situation, or zooming through space at warp speed (just be cautious not to exceed warp 10!). Many of the impressive technological advancements portrayed in the franchise are still confined to the realm of fiction. However, certain innovations inspired by Star Trek have indeed materialized in the real world. Thanks to a group of brilliant minds at the University of Pennsylvania, we can now proudly include a holodeck on that remarkable list.

Let me clarify something as we share your disappointment. We’re not referring to a futuristic world where humans can engage with characters in a holographic environment. That kind of technology is still a long way off. A team at Penn Engineering and their collaborators created the Holodeck system, which has the remarkable ability to create a wide variety of 3D environments. All you need to do is inquire.

“Language can be utilized to exert control,” stated Yue Yang, one of the co-creators. You have the ability to effortlessly describe any environments you desire and train the AI agents that inhabit them.

The holodeck system portrayed in Star Trek series such as The Next Generation and Voyager is a highly adaptable virtual environment capable of transforming simple verbal commands into fully simulated worlds. These types of environments, although smaller in scale, have significant applications in training robots.

Developing a virtual world can be quite time-consuming. “Creating these environments requires manual effort, with artists dedicating a significant amount of time to building just one,” Yang explained. To effectively train a robot to navigate real life, it is crucial to expose it to a diverse range of environments for testing purposes. Generative AI, which has gained significant popularity in recent months, appeared to be the obvious solution.

“AI systems such as ChatGPT undergo extensive training on an enormous amount of textual data, while image generators like Midjourney and DALLE are trained using a vast collection of images,” explained Chris Callison-Burch, an Associate Professor specializing in Computer and Information Science at the University of Pennsylvania.

The Holodeck utilizes a sophisticated language model known as a large language model (LLM). This powerful system, similar to the ones used in chatbots like ChatGPT, engages in a conversation with the user to determine the specific parameters of the desired environment. The system utilizes a vast digital library known as the Objaverse, which contains countless preexisting objects. It can effortlessly choose appropriate furnishings from this collection. Additionally, a layout design module ensures that the spatial arrangement of these objects is logical and coherent within the room.

Practically speaking, if you inquire about the apartment of a cat owner, Holodeck will make sure that the final room is equipped with all the necessary furniture, including a cat tree.

The team conducted a comparison between Holodeck and a previous tool called ProcTHOR. They created 120 scenes and administered a blinded test to students, asking them to indicate their preferences. Holodeck clearly outperformed its competitor in every aspect. The system demonstrated its versatility by successfully generating a wide range of unique spaces, including science labs and wine cellars.

According to co-creator Assistant Professor Mark Yatskar, the ultimate test of Holodeck is its ability to assist robots in safely navigating unfamiliar environments.

Virtual training typically focuses on residential environments, but there are countless unfamiliar worlds that a robot may encounter and must learn to navigate. Utilizing Holodeck instead of the previous tool had a significant positive impact. For instance, a robot that underwent pre-training on 100 virtual music rooms created by Holodeck demonstrated a 30 percent success rate in locating a piano, compared to just 6 percent after training with ProcTHOR.

This holodeck has the potential to make a significant impact in the field of robotics, although it may not be suitable for running a Dixon Hill holonovel.

The study is scheduled to be presented at the 2024 IEEE/CVF Computer Vision and Pattern Recognition Conference. An unpublished paper that has not undergone peer review can be accessed through arXiv.

Imagine yourself engaged in your own affairs, seated on a park bench, gazing at your mobile device. Explosion. An individual seizes your device and swiftly flees with it. While Android and iOS devices do have certain security measures, what about the brief period of time when the phone is still unlocked? Is there a method available to remotely erase its data?

Burglars can obtain a substantial amount of information within that brief duration. Each moment is significant. During the Google I/O 2024 developer conference, Google unveiled a new feature for Android called Theft Detection Lock. This feature is specifically designed to safeguard against the increasing risk of theft. Once activated, the AI-driven function will automatically secure the device.

According to Google, if your phone detects a typical movement related to theft, it will rapidly lock the screen to prevent thieves from easily accessing your data. An instance of such a stimulus is a mechanism that abruptly initiates rapid motion in the opposite direction.

Google is implementing an offline device lock feature, specifically designed to safeguard the device in the event of intentional disconnection from the network. Occurrences such as consistently failing to authenticate the phone will activate that functionality.

The forthcoming update will also introduce functionality that enhances the level of difficulty for malefactors attempting to perform a remote factory reset on your device. According to Google, this upgrade prevents thieves from setting up a stolen device again without having knowledge of your device or Google account credentials, even if they force a reset. By rendering a stolen device unsellable, it diminishes the motivation for individuals to engage in phone theft.

Biometric authentication will be mandatory for modifying sensitive information while the device is connected from an unsecured location.

As AI comes out, Google adds a “Web” search filter that shows old-school text links

Google is undergoing a transformation to adapt to the AI era. As part of this, the company is now providing AI summaries directly in its search results. Additionally, Google is introducing a new feature that allows users to filter their search results to only display text-based links. The addition of the new “Web” filter at the top of the results page will allow users to specifically filter for text links, similar to how they can currently filter for images, video, news, or shopping.

The announcement was made on Tuesday through a post on X during Google I/O, the company’s developer conference. During the conference, Google introduced significant changes to its search engine, including AI-organized search results and AI overviews in search.

Google states that the new “Web” filter will be visible either at the top of the results page or within the “More” option, depending on the specific search query.

The launch acknowledges that there are instances when individuals simply desire to display text-based links to web pages, which are typically considered less significant nowadays as Google either provides answers directly in its informational Knowledge Panels or, more recently, through AI experiments.

The Google SearchLiaison X account is noted. The post stated that this addition was made in response to feedback from users who expressed a preference for seeing only web page links in their search results. This preference may arise when users are searching for longer-form text documents, using devices with limited internet access, or simply preferring text-based results to be displayed separately from search features. “If you belong to that particular group, I hope you have a pleasant experience!”

Google has specified that on mobile devices, the new “Web” filter will be displayed by default, along with the other filters, without necessitating users to access the “More” menu. On desktop, Google will display the filters that appear to be the most pertinent to the search results.

Google announced that the feature will be gradually released to users worldwide over the course of today and tomorrow.

The announcement of a “Web” filter is bound to spark some controversy, especially among the SEO community. These experts have always strived to enhance their links in order to secure a spot on the first page of Google search results for specific keywords. However, this type of SEO manipulation has potentially diminished the usefulness of Google compared to its early days. At that time, search experts weren’t manipulating the PageRank algorithm.

The move is a significant gamble that suggests the future of search may not revolve around presenting website links. Instead, users may find the answers they are looking for in alternative forms of content or even AI responses that provide sources for those who want to explore the topic in more depth. It is yet to be determined how these changes will impact industries that heavily depend on clicks and visitors.
