On the ground at the Consumer Electronics Show (CES), legions of electronics manufacturers trample all over themselves to show off every conceivable gadget under the sun. But hidden among the shiny new technology headed to stores in 2014, there’s a whole host of bizarre pieces of electronics that we’re calling Weird CES.

Roaming the halls of the biggest gadget show on Earth, we – Samuel Gibbs and Rory Carroll – are snapping and tweeting all things weird, wonderful and vaguely unidentifiable. Here's how it works: follow the hashtag #WeirdCES. Each day around 11am PT/2pm ET, we'll send out three photos and give you the chance to guess the gadget. 

Monday's photos and answers are below. We'll add Tuesday's to the post later today.

A: this is the Sen.se Mother, a strange-looking white bulb-like hub, that connects to a series of small sensors that “blend into your daily life to make it serene, healthy and pleasurable.” The system will monitor anything from the number of steps a person makes a day to who’s in the house at the moment, and can even fire off reminders to water the plants and warn when the fridge door is left open, with Mother collecting all the data and relaying it to a phone, tablet or via notification lights.

A: the Tao Wellshell is a motion tracker and fitness gadget that uses isometrics to build a workout. It measures compressive power and produces precise exercises using the body’s own muscle power against it. The device can even be used as a game controller for things like Jetpack Joyride producing a fun workout.

A: a smart piece of jewellery, the Netatmo June bracelet monitors your exposure to the sun’s harmful UV rays and lets you keep tabs on your tanning. It connects to a smartphone app via Bluetooth to give the wearer a readout of the UV absorbed by their skin that day, so they can avoid sunburn and skin damage.
