Advancing Technology For The Pursuit Of Happiness
Back side of Tom Coughlin's IEEE Coin
On Thursday, June 12, IEEE celebrated an IEEE Engineering Milestone for the first Karaoke Machine in Tokyo. The event included a press conference and a commemorative celebration at the Karaoke rooms connected to the Shinagawa Prince Hotel.
In attendance were the family of the Karaoke inventor, Shigeichi Negishi, representatives from the Japanese Karaoke industry as well as IEEE Past President Toshio Fukuda and IEEE volunteer Dr. Tomohiro Hase, who submitted the Karaoke milestone proposal. I attended as immediate IEEE Past President. The following paragraphs are extracted and edited from my talk at the Karaoke event.
Shigeichi Negishi, who invented the earliest prototype of the karaoke machine, originally called it the Music Box. Known to start his mornings with a sing-along radio show titled "Pop Songs without Lyrics,' Shigeichi found inspiration one day in 1967 while at the offices of Nichiden Kogyo, his electronics assembly firm located in the suburbs of Tokyo.
The story goes that when his chief engineer overheard him that day and told him jokingly that he was not very tuneful, Shigeichi had the idea of attaching a microphone to a tape deck so he could hear himself over a recording of the radio show.
'Piece of cake, boss,' the engineer replied, and delivered a simple prototype three days later. Shigeichi tested it by crooning a popular ballad called Mujo no Yume or the Heartless Dream.
Over time, they expounded on the design to create the coin-operated 'Sparko Box,' an 18-inch cube with chrome fittings and multi-colored flashing lights that played selected instrumental recordings on 8-track tape cartridge, with printed lyrics provided.
The picture below shows Dr. Hase-sensei holding an 8-track tape cartridge next to an operating Sparko Box that the family brought to the event.

Despite never seeking patents or recognition, Shigeichi's impact on popular culture is undeniable. As karaoke has transcended borders and became a global phenomenon – and in what has been estimated as a more than $10 billion global industry – Shigeichi's vision of bringing people together through music endures. The image below shows the Negishi family with me and the IEEE Karaoke Engineering Milestone plaque.

So, why does something like Karaoke deserve an IEEE Engineering Milestone?
Karaoke machines, whether basic or sophisticated, are essentially audio processing systems that rely on electrical engineering principles. Karaoke systems rely heavily on computer science for their functionality, from the processing of audio and video to the software that manages song selection and display.
Karaoke systems use microphones and speakers, which require analog-to-digital converters to digitize the sound. Digital filters analyze the sound, and the system compares the user's singing to the original track, often displayed on a screen alongside the lyrics.Karaoke machines often utilize software for managing the song library, displaying lyrics, and potentially adjusting the music to fit the user's vocal range. These systems can incorporate algorithms for analyzing vocal performance, recommending songs, and even generating lyrics.Many modern karaoke systems are online, allowing users to stream music and lyrics through the internet. This requires networking technologies and cloud computing for efficient data transfer and storage.The systems handle digital audio signals, including things like compressing and decompressing audio data, as well as managing the separation of voice and instrumental tracks.The software and algorithms behind karaoke systems also contribute to the user interface and experience, making sure it's intuitive and easy to use.As the world's largest technical professional organization, it is an important part of IEEE's mission to preserve the legacy and heritage of our professions, to recognize great achievements, and to promote the importance and impact of engineering.Furthermore, Karaoke represents the use of technology to bring people together to celebrate, at a time when some other technologies seem to isolate us. I believe that Karaoke advances technology to pursue human happiness.

The Nintendo Switch 2 Is a Huge Upgrade. But It Has Some Annoying Flaws
The Legend of Zelda: Tears of the Kingdom. Nintendo Although only a few new games are currently available for the Switch 2, we actually enjoy playing the games we already own on the new console, thanks to its backward-compatibility features. Over the past several years, playing games on our original Switch consoles has often been a zen-like exercise in acceptance that games just wouldn't run very well. Even bigger releases such as Pokémon Scarlet and Pokémon Violet could be downright painful to struggle through — Wirecutter writer Kimber Streams purchased a copy at launch and couldn't get past the awful performance, so they traded it in to buy other games. However, like a number of other original Switch games, Pokémon Scarlet and Pokémon Violet have received an update for the Switch 2 that breathes new life into them, fixing performance and providing a meaningful improvement in image quality. Other games are also seeing major benefits from the Switch 2's more powerful hardware even without official updates, so we're actually considering picking up older games that might finally realize their potential on the new system. And it might just give you the perfect excuse to go back to that Animal Crossing: New Horizons island you've been neglecting (something Wirecutter editor Caitlin McGarry would rather we hadn't told her). It's fast and easy to use The Switch 2 offers a night-and-day difference in responsiveness and navigation speed in comparison with the original Switch. In 2025, almost everything about the original Switch — from maneuvering through its menus to braving the extended stuttering waits of the Nintendo eShop storefront — suffers from a molasses-like sluggishness. We had almost given up hope that this experience would ever get better, but the Switch 2 turns out to be more than capable of gliding through the same hoops, more or less, with ease. It almost makes exploring the eShop a pleasure. The move to fast game storage and microSD Express (mostly; more on that later) also results in much, much faster game-startup speeds and greatly reduced load times for games old and new. The Switch 2's Game Chat feature supports the Switch 2 Camera and uses the microphones in your Joy-Cons or Switch 2 Pro Controller. Connie Park/NYT Wirecutter We also like the promise of the Switch 2's Game Chat feature, which lets you join a party of friends with up to four simultaneous video feeds along the bottom of your screen, through the Switch 2 Camera. It isn't a revolutionary feature, but it does work easily thanks to microphones built into all of the Switch 2's official controllers, and we're excited to see how the feature develops as the Switch 2 platform matures. It feels great to hold, and the build quality is more solid Connie Park/NYT Wirecutter The original version of the Nintendo Switch, and even the offshoot Switch Lite and OLED models, felt a little unstable, but the Switch 2 feels much more solid in comparison. The new system's larger size makes it a bit easier to hold for people with slightly bigger hands, which could be a pro or a con depending on how you feel about the current Switch. But more importantly, the new Joy-Con controllers lock into place far more solidly on the right and left sides of the system courtesy of a new magnetic locking system. As a result, stressful sessions of Mario Kart World don't make us feel like we're going to break the Switch 2 as we grip the controls ever more tightly, which everyone knows makes you take corners more effectively — it's just science. (Not actually science, but it feels true.) Along with the far more useful revised kickstand design on the back of the console, which runs the entire length of the tablet, and the notably improved speaker quality, the more solid build makes the Switch 2 feel much less like a toy than its predecessor. We love the Switch 2 Pro Controller Connie Park/NYT Wirecutter For players who can't tolerate Nintendo's Joy-Con controllers, the $85 Switch 2 Pro Controller is a pricey option. But on the bright side, it's been one of our favorite controllers in our time with it so far. 'I really love the Pro Controller,' said writer Kimber Streams. 'It's comfier than the [original], and the joysticks feel much smoother and responsive.' The Switch 2 Pro Controller also includes a headphone jack and a built-in mic, which you can use with the Switch 2's Game Chat feature. All of that, combined with a much more pleasing surface texture, adds up to an amazing controller, albeit an expensive one in comparison with the original Switch Pro Controller and its $70 price tag. Mario Kart World is the best party game of 2025 (so far) Mario Kart World. Nintendo Mario Kart World takes the manic, goofy energy of previous entries in the series and doubles the player count, resulting in races that can be even more chaotic and unpredictable. It's also gorgeous and full of the kinds of personality and charm we expect from a Nintendo game, with a huge cast of characters and a ton of great tracks. However, the most important thing about Mario Kart World is how consistently it levels the playing field between video game veterans and casual players. World , like previous Mario Kart games, regularly gives the back of the pack a leg up and a way back into the race, and almost no lead is ever safe. The result is a game that families and mixed friend groups can play together without worrying too much about one or two hotshots consistently ruining everyone else's fun. Plus, the new Knockout Mode, which periodically cuts the bottom of a race's leaderboard every so often, is the kind of thing that will cause much shouting and temporarily end friendships (in a good way). And we expect that Nintendo will continue to add tracks and new goodies to Mario Kart World , straining your relationships for years to come.

We're Entering a Golden Age of Marvel Fighting Game Figures
A few weeks ago, Hasbro revealed it was cooking up a massive tribute to the legacy of Capcom's Marvel fighting games, from Children of the Atom all the way through to the legendary Marvel vs. Capcom franchise, with a series of Marvel Legends figures replicating aesthetics and matchups from across some of the most iconic fighting games ever made. But would it be a fighting game without a shock new challenger entering the ring? Last night Bandai confirmed that it would be kicking off its own 'Gamerverse' line of figures in the S.H. Figuarts range, likewise inspired by the classic Capcom Marvel games, starting with a downright glorious Cyclops that's due out this November for ¥9,900 (or around $68). Heavily inspired by the aesthetic of Bengus' artwork for the likes of Marvel vs. Capcom and X-Men vs. Street Fighter (itself drawing inspiration from Cyclops' then-current Jim Lee suit from the '90s refresh of the X-Men comics), the figure is more than just Bandai's first crack at comics-inspired X-Men figures (the Figuarts line has had a few mutant entries via movie adaptations, most notably Deadpool and Wolverine via their appearances in Deadpool & Wolverine). It's a celebration of Cyclops specifically as he appeared in those classic fighting games. View this post on InstagramIt's very cool to see the SHF Cyclops hitting all the poses you'd want him to hit from those early games, from his legendarily sassy Optic Blast pose, to hitting a Gene Splice uppercut, to, of course, using a set of back sheets to replicate his massive Mega Optic Blast hyper combo. He can even do his little x-hand pose before he fires, to boot! But what's most interesting about this wave of merchandising nostalgia for the early Marvel/Capcom games—off of the back of the re-release of several of the classic games in the Marvel vs. Capcom Fighting Collection last year—is that they're now all dropping right as Marvel's fighting game legacy prepares to move away from Capcom itself. The start of this month saw Sony make a surprise reveal of Marvel Tōkon: Fighting Souls, a new tag-team fighter in the vein of those classic Capcom titles, but made by Guilty Gear's Arc Systems Works. It was the first major Marvel fighting game not developed by Capcom in years, and came in the wake of the disappointing release of Marvel vs. Capcom Infinite back in 2017. The MvC series had spent nearly a decade wash with disappointment for the latest title, while also patting itself on the back for the legacy that had come before it. Now, on the video game front, that legacy is preparing to go elsewhere. But on your toy shelf, at least, it's staying firmly put in Capcom's court. Want more io9 news?
