I don"t care who it is," Drexler said during a LinkedIn interview on April 10, adding that the title goes against his leadership philosophy of being on the same level as the people around him. "Even in restaurants, I [tell people to call me] Mickey, that"s it. I want them to feel not beneath me."</p><p>Drexler"s accolades in the apparel industry are lengthy, from revitalizing Ann Taylor and turning Gap into a $14 billion powerhouse to founding brands like Old Navy and Madewell. He also served as an Apple board member from 1999 to 2015.</p><p>But no matter his accomplishments, Drexler insisted that he"s no better than your average employee, and other bosses should have a similar outlook, he said.

He added that employees should also look for a boss that has "adaptability and someone that"s empowering you to grow."</p><p>Drexler converses with his colleagues, both entry-level and executive, by asking simple, open-ended questions about their job or upbringing, he said. He calls it "schmoozing," but you might refer to it as small talk or networking — creating a connection with an informal, friendly interaction.</p><p>"Meet all the people," said Drexler, adding that small talk is a skill he developed as an executive, not something he"s always done.

3112868	有图 <p> <p> <p><i></i>Back to News</p> <p><time>April 22 "25</time></p> <p> 3D modeling you can feel </p> <p> Written By <p> <p>Adam Conner-Simons</p> </p> </p> </p> </p> <p> <p> <p> <p> <p> <p> <img src="https://www.csail.mit.edu/sites/default/files/2025-04/MIT-TactStyle.png" rel="noopener noreferrer"></p> </p> </p> <p> <p> <p>Essential for many industries ranging from Hollywood computer-generated imagery to product design, 3D modeling tools often use text or image prompts to dictate different aspects of visual appearance, like color and form. As much as this makes sense as a first point of contact, these systems are still limited in their realism due to their neglect of something central to the human experience: touch.</p><p>Fundamental to the uniqueness of physical objects are their tactile properties, such as roughness, bumpiness, or the feel of materials like wood or stone. Existing modeling methods often require advanced computer-aided design expertise and rarely support tactile feedback that can be crucial for how we perceive and interact with the physical world.</p><p>With that in mind, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have created a new system for stylizing 3D models using image prompts, effectively replicating both visual appearance and tactile properties.</p><p>The CSAIL team’s “TactStyle” tool allows creators to stylize 3D models based on images while also incorporating the expected tactile properties of the textures. TactStyle separates visual and geometric stylization, enabling the replication of both visual and tactile properties from a single image input.</p><p>PhD student Faraz Faruqi, lead author of a new paper on the project, says that TactStyle could have far-reaching applications, extending from home decor and personal accessories to tactile learning tools. TactStyle enables users to download a base design — such as a headphone stand from Thingiverse — and customize it with the styles and textures they desire. In education, learners can explore diverse textures from around the world without leaving the classroom, while in product design, rapid prototyping becomes easier as designers quickly print multiple iterations to refine tactile qualities.</p><p>“You could imagine using this sort of system for common objects, such as phone stands and earbud cases, to enable more complex textures and enhance tactile feedback in a variety of ways,” says Faruqi, who co-wrote the paper alongside MIT Associate Professor Stefanie Mueller, leader of the Human-Computer Interaction (HCI) Engineering Group at CSAIL. “You can create tactile educational tools to demonstrate a range of different concepts in fields such as biology, geometry, and topography.”</p><p>Traditional methods for replicating textures involve using specialized tactile sensors — such as GelSight, developed at MIT — that physically touch an object to capture its surface microgeometry as a “heightfield.” But this requires having a physical object or its recorded surface for replication. TactStyle allows users to replicate the surface microgeometry by leveraging generative AI to generate a heightfield directly from an image of the texture.</p><p>On top of that, for platforms like the 3D printing repository Thingiverse, it’s difficult to take individual designs and customize them. Indeed, if a user lacks sufficient technical background, changing a design manually runs the risk of actually “breaking” it so that it can’t be printed anymore. All of these factors spurred Faruqi to wonder about building a tool that enables customization of downloadable models on a high level, but that also preserves functionality.</p><p>In experiments, TactStyle showed significant improvements over traditional stylization methods by generating accurate correlations between a texture’s visual image and its heightfield. This enables the replication of tactile properties directly from an image. One psychophysical experiment showed that users perceive TactStyle’s generated textures as similar to both the expected tactile properties from visual input and the tactile features of the original texture, leading to a unified tactile and visual experience.</p><p>TactStyle leverages a preexisting method, called “Style2Fab,” to modify the model’s color channels to match the input image’s visual style. Users first provide an image of the desired texture, and then a fine-tuned variational autoencoder is used to translate the input image into a corresponding heightfield. This heightfield is then applied to modify the model’s geometry to create the tactile properties.</p><p>The color and geometry stylization modules work in tandem, stylizing both the visual and tactile properties of the 3D model from a single image input. Faruqi says that the core innovation lies in the geometry stylization module, which uses a fine-tuned diffusion model to generate heightfields from texture images — something previous stylization frameworks do not accurately replicate.</p><p>Looking ahead, Faruqi says the team aims to extend TactStyle to generate novel 3D models using generative AI with embedded textures. This requires exploring exactly the sort of pipeline needed to replicate both the form and function of the 3D models being fabricated. They also plan to investigate “visuo-haptic mismatches” to create novel experiences with materials that defy conventional expectations, like something that appears to be made of marble but feels like it’s made of wood.</p><p>Faruqi and Mueller co-authored the new paper alongside PhD students Maxine Perroni-Scharf and Yunyi Zhu, visiting undergraduate student Jaskaran Singh Walia, visiting masters student Shuyue Feng, and assistant professor Donald Degraen of the Human Interface Technology (HIT) Lab NZ in New Zealand.</p> </p> <p> People <p> <p> <p> <p> <img src="https://www.csail.mit.edu/themes/custom/csail/images/core-images/default-headshot.png" rel="noopener noreferrer"> </p> Faraz Faruqi </p> </p> <p> <p> <p> <p> <img src="https://www.csail.mit.edu/sites/default/files/styles/headshot/public/images/people/card/stefanie-mueller-profile-picture_0.jpg?h=ce37fd2f&itok=UuteMVub" rel="noopener noreferrer"></p> </p> Stefanie Mueller </p> </p> </p> <p> Research Areas <p> <p> <p>Graphics & Vision</p> </p> <p> <p>Human-Computer Interaction</p> </p> </p> </p> <p> Impact Areas <p> <p> <p>Entertainment</p> </p> <p> <p>Manufacturing</p> </p> </p> </p> <p> Press Contact <p> Rachel Gordon <p> <p>Erachelg@csail.mit.edu</p> <p>T258-0675</p> </p> </p> </p> <p> <p> <p>RELATED</p> <p> <p>“TactStyle: Generating Tactile Textures with Generative AI for Digital Fabricat…</p> <p>Department of Electrical Engineering and Computer Science (EECS)</p> <p>School of Engineering</p> </p> </p> </p> Related News <p> <p> <p> <p> <p> <p> <p> <p> <img src="https://www.csail.mit.edu/sites/default/files/styles/large/public/2025-03/MIT-Xstrings.png?itok=tx5OhBSJ" rel="noopener noreferrer"></p> </p> <p> Human-Computer Interaction Entertainment Manufacturing </p> </p> <p> <p><time>March 18 "25</time></p> 3D printing approach strings together dynamic objects for you <p>“Xstrings” method enables users to produce cable-driven objects, automatically assembling bionic robots, sculptures, and dynamic fashion designs.</p> </p> </p> <p> <p> 3D printing approach strings together dynamic objects for you </p> </p> </p> <p> <p> <p> <p> <p> <p> <img src="https://www.csail.mit.edu/sites/default/files/styles/large/public/2023-09/MIT-Style2Fab-01-press_0.jpeg?itok=rQQJE8p-" rel="noopener noreferrer"></p> </p> <p> AI & ML Graphics & Vision Human-Computer Interaction Health Care Manufacturing </p> </p> <p> <p><time>September 15 "23</time></p> AI-driven tool makes it easy to personalize 3D-printable models <p>With Style2Fab, makers can rapidly customize models of 3D-printable objects, such as assistive devices, without hampering their functionality.</p> </p> </p> <p> <p> AI-driven tool makes it easy to personalize 3D-printable models </p> </p> </p> </p> </p> </p> </p> 3D modeling you can feel \| MIT CSAIL	查看 10661	MIT计算机科学与人工智能实验室	2025-04-22 20:00:00 2025-04-24 18:14:53	word

Photo: U.S. Army </p> </p><p>A team from MIT Lincoln Laboratory has built and demonstrated the Wideband Selective Propagation Radar (WiSPR), a system capable of seeing out various distances at millimeter-wave (MMW) frequencies. Typically, these high frequencies, which range from 30 to 300 gigahertz (GHz), are employed for only short-range operations. Using transmit-and-receive electronically scanned arrays of many antenna elements each, WiSPR produces narrow beams capable of quickly scanning around an area to detect objects of interest. The narrow beams can also be manipulated into broader beams for communications.</p><p>"Building a system with sufficient sensitivity to operate over long distances at these frequencies for radar and communications functions is challenging," says Greg Lyons, a senior staff member in the Airborne Radar Systems and Techniques Group, part of Lincoln Laboratory"s ISR Systems and Technology R&D area. "We have many radar experts in our group, and we all debated whether such a system was even feasible. Much innovation is happening in the commercial sector, and we leveraged those advances to develop this multifunctional system."</p><p>The high signal bandwidth available at MMW makes these frequencies appealing. Available licensed frequencies are quickly becoming overloaded, and harnessing MMW frequencies frees up considerable bandwidth and reduces interference between systems. A high signal bandwidth is useful in a communications system to transmit more information and in a radar system to improve range resolution (i.e., ability of radar to distinguish between objects in the same angular direction but at different distances from the radar).</p><p>The phases for success</p><p>In 2019, the Laboratory team set out to assess the feasibility of their MMW radar concept. Using commercial off-the-shelf radio-frequency integrated circuits (RFICs), which are chips that send and receive radio waves, they built a fixed-beam system (only capable of staring in one direction, not scanning) with horn antennas. During a demonstration on a foggy day at Joint Base Cape Cod, the proof-of-concept system successfully detected calibration objects at unprecedented ranges. </p><p>"How do you build a prototype for what will eventually be a very complicated system?" asks program manager Christopher Serino, an assistant leader of the Airborne Radar Systems and Techniques Group. "From this feasibility testing, we showed that such a system could actually work and identified the technology challenges. We knew those challenges would require innovative solutions, so that"s where we focused our initial efforts."</p><p>WiSPR is based on multiple-element antenna arrays. Whether serving a radar or communications function, the arrays are phased, which means the phase between each antenna element is adjusted. This adjustment ensures all phases add together to steer the narrow beams in the desired direction. With this configuration of multiple elements phased up, the antenna becomes more directive in sending and receiving energy toward one location. (Such phased arrays are becoming ubiquitous in technologies like 5G smartphones, base stations, and satellites.)</p><p>To enable the tiny beams to continuously scan for objects, the team custom-built RFICs using state-of-the-art semiconductor technology and added digital capabilities to the chips. By controlling the behavior of these chips with custom firmware and software, the system can search for an object and, after the object is found, keep it in "track" while the search for additional objects continues — all without physically moving antennas or relying on an operator to tell the system what to do next.</p><p>"Phasing up elements in an array to get gain in a particular direction is standard practice," explains deputy program manager David Conway, a senior staff member in the Integrated RF and Photonics Group. "What isn"t standard is having this many elements with the RF at millimeter wavelengths still working together, still summing up their energy in transmit and receive, and capable of quickly scanning over very wide angles."</p><p>For the communications function, the team devised a novel beam alignment procedure.</p><p>"To be able to combine many antenna elements to have a radar reach out beyond typical MMW operating ranges — that"s new," Serino says. "To be able to electronically scan the beams around as a radar with effectively zero latency between beams at these frequencies — that"s new. Broadening some of those beams so you"re not constantly reacquiring and repointing during communications — that"s also new."</p><p>Another innovation key to WiSPR"s development is a cooling arrangement that removes the large amount of heat dissipated in a small area behind the transmit elements, each having their own power amplifier.</p><p> <p> <p> <img src="https://www.ll.mit.edu/sites/default/files/news/image/2025-04/Ryan_Sean_VerifyingMechanicalPointingWiSPRUnitsOnTripods_530594-023.jpg" rel="noopener noreferrer"></p> <p>Ryan Lewis (front) and Sean Turner verify the mechanical alignment of two WiSPR units during preliminary field testing.

WiSPR technology has since been transitioned to a vendor for production. By adopting WiSPR, Army units will be able to conduct their missions more effectively.</p><p>"We"re anticipating that this system will be used in the not-too-distant future," Lyons says. "Our work has pushed the state of the art in MMW radars and communication systems for both military and commercial applications."</p><p>"This is exactly the kind of work Lincoln Laboratory is proud of: keeping an eye on the commercial sector and leveraging billions-of-dollars investments to build new technology, rather than starting from scratch," says Lincoln Laboratory Assistant Director Marc Viera.</p><p>This effort supported the U.S. Army Rapid Capabilities and Critical Technologies Office.
