WCs meet PCs: converged tech toilets show promise


Microsoft's decision to flush away its iLoo project may have disappointed many readers, but some of the boldest technology research is taking place in our restrooms.

MIT's Dan Maynes-Aminzade is just one pioneer putting the PC into the WC. He's the co-author of " You're In Control " - the pun is intentional - a research project which thanks to a microcontroller and an uh, embedded x86 box, enhances the micturation process.

You're In Control has as many potential uses as we have toilet gags. The system "uses computation to enhance the act of urination. Sensors in the back of a urinal detect the position of a stream of urine, enabling people to play interactive games on a screen mounted above the urinal," according to the website.

Was this a joke, we wondered?

"Yes and no," Dan told us. "It's tapping into the almost primal feeling of marking your territory that comes with urination," he tell us.

"There's a lot of competition in toilets," notes Dan, who explains that the system lends itself to multiplayer games. "It really would be pissing contest," he points out. But the potential for interactive entertainment doesn't stop there.

"There are also carnival games: squirting water into clown's mouth where the balloon inflates."

No wonder clowns look so unhappy when they're offstage. If only they knew.


However , You're In Control has more serious uses, too. Dan envisages real-time urine analysis hooking up to drug tests or pregnancy tests. A PCWC might even combine the data to print a horoscope.

One difficulty he acknowledges is that it favors men. "Women are a little disappointed that they can't use the system. I don't think it's realistic to expect women to urinate standing up."

You're In Control was a side project for Dan, a grad student whose main research topic explores tangible user interfaces. The system made its debut at the CHI human interface research conference in April, where Maynes-Aminzade and co-researcher Hayes Raffle met with a Scandinavian toilet project.

A thoughtful paper entitled "The Toilet Entertainment System", by two researchers at IT-University of Gotenborg, Sweden, Par Stenberg and Johan Thoresson was also presented at the CHI conference.

"A toilet is a sheltered place for contemplation and reflection," note Stenberg and Thoresson, "even though some people are having problems with the solitude due to the fact that they are used to a constant flow of inputs and impressions."

The TES projects news or SMS text messages onto the bathroom tiles.

"How the visitor acts upon the information is something that is yet to be answered," they note.

Clearly a call for more research, and for potential VCs? This is no less potty than WiFi replacing digital cellular networks. ®

    Plus: Yandex releases 100-billion-parameter language model for free, and more

    In brief US hardware startup Cerebras claims to have trained the largest AI model on a single device powered by the world's largest Wafer Scale Engine 2 chip the size of a plate.

    "Using the Cerebras Software Platform (CSoft), our customers can easily train state-of-the-art GPT language models (such as GPT-3 and GPT-J) with up to 20 billion parameters on a single CS-2 system," the company claimed this week. "Running on a single CS-2, these models take minutes to set up and users can quickly move between models with just a few keystrokes."

    The CS-2 packs a whopping 850,000 cores, and has 40GB of on-chip memory capable of reaching 20 PB/sec memory bandwidth. The specs on other types of AI accelerators and GPUs pale in comparison, meaning machine learning engineers have to train huge AI models with billions of parameters across more servers.

  • Zendesk sold to private investors two weeks after saying it would stay public
    Private offer 34 percent above share price is just the thing to change minds

    Customer service as-a-service vendor Zendesk has announced it will allow itself to be acquired for $10.2 billion by a group of investors led by private equity firm Hellman & Friedman, investment company Permira, and a wholly-owned subsidiary of the Abu Dhabi Investment Authority.

    The decision is a little odd, in light of the company's recent strategic review, announced on June, which saw the board unanimously conclude "that continuing to execute on the Company's strategic plan as an independent, public company is in the best interest of the Company and its stockholders at this time."

    That process saw Zendesk chat to 16 potential strategic partners and ten financial sponsors, including a group of investors who had previously expressed conditional interest in acquiring the company. Zendesk even extended its discussions with some parties but eventually walked away after "no actionable proposals were submitted, with the final bidders citing adverse market conditions and financing difficulties at the end of the process."

  • Singapore promises 'brutal and unrelentingly hard' action on dodgy crypto players
    But welcomes fast cross-border payments in central bank digital currencies

    In the same week that it welcomed the launch of a local center of excellence focused on crypto-inspired central bank digital currencies, Singapore's Monetary Authority (MAS) has warned crypto cowboys they face a rough ride in the island nation.

    The center of excellence (COE) was established by the Mojaloop Foundation – an open source effort to create payment platforms to make digital financial services accessible to those without access to banks. The COE aims to "accelerate financial inclusion in emerging markets" through hackathons, workshops and pilot projects while examining expanded CBDCs payment capabilities."

    Singapore's sovereign wealth fund has invested in Mojaloop, and MAS chief fintech officer Sopnendu Mohanty serves as a board advisor and the authority provides representatives to the Foundation's working group, alongside folks from the Bill & Melinda Gates Foundation, Google, and more.
