A new Review on artificial touch systems stresses aligning feedback with the brain's learning and adaptation processes to design interfaces that are intuitive, flexible, and better suited to human needs, allowing users to feel and act more naturally. scim.ag/4gFrE01

6/8 To ensure the relevant information is well received by the user, engineers rely on above-threshold perception. Yet, much of natural haptics is implicit. If we constantly bombard the system with above-perceptual-threshold haptic information, we risk overwhelming the user

7/8 These gaps between biomimicry and current technology put the load on the user’s cognition, who ultimately needs to learn to infer the intended information from the interface, while ignoring irrelevant features... So, how can we put the technology back in the background?

8/8 Read our review for some ideas! Ultimately, physiological compatibility (biomimicry) is too far from current technological reality. Also, it limits design and functionality to what is biologically familiar. Instead, we advocate for behavioural and cognitive compatibility.

4/8 The somatosensory system relies on an orchestra of many inputs across modalities, some not reaching awareness. For an engineer, most of these inputs are not sufficiently informative to justify the hardware and processing time.

5/8 Limited bandwidth gets worst during delivery of feature-specific and context-invariant artificial input to the user. Whereas the somatosensory system is dynamically attuned to context, like movement planning, stimulus repetition and learning, making it highly non-linear.

2/8 Artificial haptic technologies have the potential to empower users with new ways to perceive and engage with their surroundings. Yet, they are also slow to reach their target users and cross the chasm from the lab to real life. Why is that? We have some thoughts.

3/8 To begin with, the strive for biomimicry––attempting to mimic the peripheral input so that the CNS integrates the artificial input to the natural system––requires haptic feedback systems to capture relevant environmental data, via sensors and filters. But what is ‘relevant’?

Proud to share a new review (more like a long perspective), just out in Science Advances: science.org/doi/10.1126/scia… . Ilana Nisky @NiskyLab Makin @plasticity_lab and I joined heads (brains) to reimagine how to make the most out of artificial haptic interfaces. A thread (1/8)

A neurocognitive pathway for engineering artificial touch

Neurocognitive congruence is key to designing artificial touch that best integrates with human perception and action.

1/🚀 Excited to share our new research! 🎉 This study, led by the talented Hanna Kossowsky Lev, explores the fascinating interplay between perception and action in haptics. 🔗 Read more: eneuro.org/content/early/202…

Can Information About Stiffness Perception be Inferred from Action Signals Using Models?

We use sensory feedback to form our perception, and control our movements and forces (actions). There is an ongoing debate about the relation between perception and action, with evidence in both...

I'm an Israeli Arab. I'm Embarrassed—and Hamas Is to Blame

Israeli Arabs and Jews are like salt and pepper: Both belong on the table, and once they're sprinkled into a dish, it's impossible to distinguish between them.

These children have been stolen from their families and buried alive in the tunnels of Gaza, held as hostages by Hamas terrorists. These children are real. Their pain is real. They need to come home.

Some scientific news - the paper of @FarajianMor on Direction-Specific Effects of Artificial Skin-Stretch on Stiffness Perception and Grip Force Control is now accepted for publication - it is the last paper of her impressive PhD work in collaboration with @RazWazziLeib

Artificial skin-stretch augmented the perceived stiffness; but the augmentation by the negative stretch was lower than by the positive stretch, and for some participants, it was opposite. A model of the preferred directions of the mechanoreceptors explains these results.
