The Handle Is the Signal

Apple introduced HomeView, a $299 seven-inch shared display that recognizes up to six household members and changes personal content accordingly. Private context depends on a recognized face and paired-device state; Apple says access can persist after that device leaves Wi-Fi if additional location and connectivity conditions hold. The Verge operated home controls and met a face-or-iPhone check on door unlock, but neither it nor Gizmodo independently tested identity switching outside Apple's demonstrations.

A numerical study mapped blue, green, gold and terracotta photovoltaic coatings across four metal oxides, four encapsulants and two cell technologies. Its laminated three-layer model reached all four target colors, yet disorder did not remove angular change: modeled daytime drift ranged from ΔE00 5 to 18, with terracotta the most stable and façade geometry shifting every tested color toward blue. The preprint does not report fabricated modules, retained photocurrent, outdoor durability, manufacturability or cost.

A four-mode residual controller compares commanded and realized robot motion, derives one stiffening direction from the policy's action chunk, holds extra stiffness while progress resumes and releases it afterward. Across cap-unscrewing and T-slot pushing at six resistance levels—two withheld from demonstrations—aggregate success rose from 52% to 90%. At the hardest push, directional stiffening produced 18.3 N median off-axis force versus 47.5 N for uniform stiffening, but the study used one Franka setup, two tasks and five trials per condition and does not cover contacts that should make the robot more compliant.

Researchers translated modeled tactile-afferent activity into twelve electrotactile pulse patterns and tested them in three fixed-order sessions with 16 healthy participants. Joint amplitude-and-frequency modulation produced a reported pressure probability of 0.78 with irritation probability 0.24; synchronized video and mimed button motion raised pressure reports and mean naturalness without a clear irritation increase. The study used one three-second button scenario, later cue sessions always followed the no-cue session, and naturalness remained concentrated around 2–3 on a 0–5 scale.

A battery-free skin patch uses an isolated optical cavity to measure normal pressure from 0–100 kPa and biaxial shear to 15 kPa, while dual-wavelength reflectance tracks erythema and NFC links multiple sensors. Its model reported normalized RMSE of 3.2%, 3.6% and 5.8% for two shear axes and pressure; tests included 1,000 pressure cycles, 500 shear cycles, 25 hours under static load and six hours of wireless posture monitoring with eight sensors. Human evidence remains small: erythema comparison used three participants and the simulated-bed array one, with no patient cohort, injury outcome or broad skin-tone and repeated-wear evaluation.
