ActiWear is part of the EMS training ecosystem of XBody. EMS training is based on the idea of stimulating the muscles during workout with external electro impulses. 
We were inspired by the amazing technology and efficiency of this system. As a newcomer, ActiWear had to fit with the suite and the kiosk, but also had to introduce a new approach. It is compact simple and organic, sleek and seamlessly shaped, like a river rock.

Fitting all the requirements of a fitness wearable was our greatest challenge. We had to consider anthropometric data and functional usability issues for setting up and connecting the device. Working in close cooperation with the engineers gave us the opportunity to make the wearable part as small as possible. Combined with the custom designed belt, the ActiWear is easy to use with no effect on the workout activities.

ActiWear enables users to set up wireless training for up to 6 people. With its 12+ hours of battery life, it can operate all day without charging. It offers easy physical connectivity with its magnetic connector and easy digital connectivity with NFC-based quick pairing.

Users interact with ActiWear during the whole training process. This device is responsible for sending EMS signals to the electrodes stimulating the muscles of the users. There are three main interaction points that influence the user experience in particular: putting the belt and the ActiWear device on, getting them off, and not being bothered by them during the training in between. Attaching and detaching the belt is supported by a velcro surface – the activity is usually assisted by a trainer, but it can easily be done by the user himself. Due to its small size, light weight and seamlessly rounded shape, the device itself can remain unnoticed during the workout.

3D modeling, design for manufacturing

Our research covered the training activity and the connection process, as well as the preparation, where users are sprinkled with water to help conduction. We also studied stresses occurring in the casing during unusual activities: falling, laying on the device etc. The design was carried out until the very end of the DFM process.
