Cut those awkward heart-rate-monitor straps with TomTom’s Runner Cardio GPS watch

By Lee Crane Published April 7, 2014

Runners tired of licking their heart-rate-monitor straps and girding them to their chests before every run will finally be freed from that ritual with TomTom’s new Runner Cardio and Multisport Cardio GPS watches. That’s because the latest version of the Amsterdam-based company’s fitness GPS watches now feature built-in optical heart rate monitoring technology from Mio. Using a light on the back of the watch, the Mio monitors changes in blood flow and tracks heart rate without the use of extra straps or sensors.

This technology also makes it easier for athletes to stay on target by displaying heart rate and using alarms to notify the runner when a certain heart rate has been reached. The Runner places heart rates into five zones: sprint, speed, endure, fat burn, and easy. Set the target and the watch does the rest … well, except for the running.

Like the previous versions of the Runner, the Cardio version tracks and display pace, speed, distance, and calories burned. The Multisport Cardio connects to cycling sensors like speed and cadence using Bluetooth Smart. After the run or ride all the data can be uploaded to Web fitness-tracking sites like TomTom’s MySports, MapMyFitness, RunKeeper, TrainingPeaks or Strava so athletes can let friends or coaches see all the hard work they’ve been doing.

The Runner Cardio is available now for pre order on the TomTom website for $270. The Multisport, which also connects to Bluetooth Smart cadence and speed sensors is $300.

A new startup wants to fix the military’s working-dog shortage with cloning and gene editing

Promising pitch, plenty of unanswered questions about the dogs.

Military working dogs charge into places the rest of us would flee. So, I understand why anyone would want to breed tougher, healthier dogs for the job.

Warhound, a new startup from Colossal Biosciences co-founder Ben Lamm and Anduril co-founder Palmer Luckey, has stepped out of stealth with $200 million to clone and gene-edit working dogs for American troops, police departments, and emergency services (via TechCrunch).

AI can describe a picture, but it still struggles to understand blind users

A University of Maryland study finds that Be My AI often buries useful answers in lengthy descriptions, leaving blind users to work harder to get the information they need.

AI can describe a picture, identify objects, and answer questions about what a camera sees. But when a blind user needs a quick answer, getting an entire spoken essay about the scene isn't exactly helpful. Researchers at the University of Maryland (UMD) have found that AI-powered visual assistance can leave blind users doing too much work to get the information they actually need.

The study, titled Say It My Way: Exploring Control in Conversational Visual Question Answering with Blind Users, examined how people interact with Be My AI, an AI-powered feature of the Be My Eyes app. The researchers found that users often received lengthy descriptions that didn't adequately address their immediate goals, forcing them to ask follow-up questions or find ways to steer the AI towards a more useful answer.

Etsy cracks down on AI slop listings. Everyone else needs to take note.

Now every platform must decide what counts as handmade.

Platforms tend to shrug off AI clutter until it threatens what they sell. For Etsy, that thing is trust in the maker.

To protect that, Etsy has banned AI-generated how-to guides and listings made entirely by bots. Most sellers must show at least one unretouched photo of the item (via Etsy Seller Handbook).
