The device can operate continuously for <strong>30 days<\/strong> on a single charge.<\/p>\n\n\n\n<p>While traditional computer mice have been the most fundamental tool for digital interaction for years, the need for more natural input methods is increasing as technology becomes more portable and <strong>wearable<\/strong>. In this context, researchers at the <strong>University of Tokyo<\/strong> have developed a new wearable controller that could make <strong>Augmented Reality (AR)<\/strong> technologies more intuitive and energy-efficient. Named <strong>\u201cpicoRing,\u201d<\/strong> this ring-shaped wireless mouse weighs just <strong>5 grams<\/strong> and offers up to <strong>30 days of continuous use<\/strong> on a single charge.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">The Prototype Device Holds Great Potential<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"720\" height=\"405\" src=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/10\/indir-1-9.webp\" alt=\"\" class=\"wp-image-30711\" srcset=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/10\/indir-1-9.webp 720w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/10\/indir-1-9-300x169.webp 300w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/10\/indir-1-9-390x220.webp 390w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/10\/indir-1-9-150x84.webp 150w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><\/figure>\n\n\n\n<p>Researchers noted that previous smart rings, with batteries of only 50\u201360 mWh capacity, could not power the communication needed for a long duration. They stated that the picoRing solves this problem with <strong>hundreds of times lower power consumption<\/strong> (approximately <strong>30\u2013500 microwatts<\/strong>).<\/p>\n\n\n\n<p>To reduce the communication load on the ring, the team designed a <strong>watch-like wristband<\/strong>. This wristband acts as a <strong>signal relay<\/strong> between the ring and the connected device, allowing the ring to use much weaker but <strong>energy-efficient communication components<\/strong>.<\/p>\n\n\n\n<p>To achieve this energy efficiency, the researchers developed a new communication system called <strong>semi-passive inductive telemetry (semi-PIT)<\/strong>. This system consists of wire coils supported by capacitors and naturally amplifies magnetic fields to <strong>increase the communication distance without using an active amplifier<\/strong>. In principle, this is similar to NFC. The resulting 5-gram <strong>picoRing<\/strong> can transmit data with <strong>minimum energy<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"picoRing mouse: ultra-low-power ring-based wireless tinymouse\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/7RazVNMx0Ms?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Although the picoRing is still in the prototype phase, the technology is noted to have the potential to not only control AR glasses but also form the foundation for <strong>long-lasting wearable devices and health sensors<\/strong>. However, it is stated that the device is still relatively large, experiences interference in noisy wireless environments, and currently only supports <strong>simple interactions (scrolling, clicking, etc.)<\/strong>.<\/p>\n\n\n\n<p>The research team plans to increase the comfort and reliability of picoRing in the future, as well as replace the wristband with <strong>conductive fabrics<\/strong> or alternative wireless relays. It is also mentioned that the ring could be adapted for <strong>health applications<\/strong> that measure biometric data such as heart rate or stress levels.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">You Might Also Like;<\/h3>\n\n\n<ul class=\"wp-block-latest-posts__list wp-block-latest-posts\"><li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/metaverseplanet.net\/blog\/decoding-toyotas-cue7-basketball-robot\/\">The AI Revolution on the Court: Decoding Toyota&#8217;s CUE7 Basketball Robot<\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/metaverseplanet.net\/blog\/the-dark-side-of-nanotechnology\/\">The Dark Side of Nanotechnology: Could Microscopic Swarms Erase Billions?<\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/metaverseplanet.net\/blog\/the-illusion-of-digital-immortality\/\">The Illusion of Digital Immortality: Are You Really Uploading Your Mind?<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Researchers have developed a ring-shaped mouse called picoRing that simplifies the control of Augmented Reality (AR) glasses.
