2/ We sought to expand the repertoire of ICMS-based artificial #touch to confer greater dexterity to brain-controlled bionic hands. We conveyed info about the local geometrical features of objects, leveraging our understanding of how these sensory features are encoded in #S1.

Giacomo Valle1 year ago

3/ First, we simultaneously delivered spatially-patterned ICMS through electrodes whose projected fields – the patch of skin over which the sensation is experienced – were arranged in a line. Unprompted, the participants reported the sensation of an #edge.

Giacomo Valle1 year ago

4/ Adding temporal patterning to the paradigms, we sequentially delivered ICMS through electrodes, which induced sensations of #movement across their skin. We could also systematically manipulate the #direction and #speed of perceived motion across the skin.

Giacomo Valle1 year ago

5/ Finally, we integrated this rich feedback in the brain-controlled bionic hand! We conclude that principled spatiotemporal patterning of ICMS can evoke #rich and #complex sensations to expand the repertoire of artificial touch in bionic hands.

MotionGPT: Human Motion as a Foreign Language paper page: Though the advancement of pre-trained large language models unfolds, the exploration of building a unified model for language and other multi-modal data, such as motion, remains challenging and untouched so far. Fortunately, human motion displays a semantic coupling akin to human language, often perceived as a form of body language. By fusing language data with large-scale motion models, motion-language pre-training that can enhance the performance of motion-related tasks becomes feasible. Driven by this insight, we propose MotionGPT, a unified, versatile, and user-friendly motion-language model to handle multiple motion-relevant tasks. Specifically, we employ the discrete vector quantization for human motion and transfer 3D motion into motion tokens, similar to the generation process of word tokens. Building upon this "motion vocabulary", we perform language modeling on both motion and text in a unified manner, treating human motion as a specific language. Moreover, inspired by prompt learning, we pre-train MotionGPT with a mixture of motion-language data and fine-tune it on prompt-based question-and-answer tasks. Extensive experiments demonstrate that MotionGPT achieves state-of-the-art performances on multiple motion tasks including text-driven motion generation, motion captioning, motion prediction, and motion in-between.

EXCLUSIVE HAUSA INTERVIEW: Prof. Aliyu Muhammad Bunza, a Professor of African Culture, speaks on the roots of banditry in northern Nigeria. According to Prof. Bunza, the Fulani were pushed into banditry by the Hausa, arguing that tensions between farming and pastoralism existed long before the arrival of Sheikh Usman Dan Fodio. An interesting perspective on the historical roots of the region’s banditry crisis

IKEA deployed an AI chatbot named Billy to handle level-one customer service inquiries. It reportedly resolved around 57% of those engagements without human escalation. Most companies would have celebrated the labor savings and stopped there. Cost takeout right? But the more interesting move was to study the 43% of cases Billy could not resolve. Those unresolved inquiries pointed to customer demand for interior design help. IKEA responded by spinning up a design consultancy, reskilling customer service employees powered by AI, and creating a new revenue stream that generated roughly €1 billion in new revenue in its 1st year. Automation + Augmentation = Exponential Growth 💪🦾📈 Story here:

I was really impressed by the UMI gripper (Cheng Chi et al.), but a key limitation is that **force-related data wasn’t captured**: humans feel haptic feedback through the mechanical springs, but the robot couldn’t leverage that info, limiting the data’s value for fine-grained manipulation tasks. Led by my amazing students Yolanda Zhu and Binghao Huang, we designed a **portable visuo-tactile gripper** by integrating our dense, flexible tactile arrays with the UMI gripper to enable large-scale in-the-wild data collection. 🔗 We demonstrate **cross-modal representation learning** and **downstream policy learning** on tasks requiring in-hand state estimation (e.g., test tube reorientation) and fine-grained force sensing (e.g., pipette fluid transfer). Key takeaways: - Our flexible tactile arrays store the rich haptic information humans perceive as dense tactile signals. - Portability and robustness are key for in-the-wild data collection; our portable gripper is compact, lightweight, and durable. - Touch provides precise, robust measurements of in-hand object pose, invariant to lighting and viewpoint. - Cross-modal pretraining on large-scale in-the-wild data significantly improves policy robustness and sample efficiency (as shown many times before — and verified again here!). Also check out our previous investigations of dense, flexible tactile grids for understanding human-robot-environment interactions: - Dense tactile glove (Nature ’19): - 3D-ViTac (CoRL ’24):
