Group of leading wearable researchers from Tampere University of Technology and consumer electronics experts agreed to put their heart and passion into developing together unique innovation that would start a new era in wearablebusiness.They realized that world is lacking wearable technologies that could be part of products that people use every day, everywhere.Today there starts to be an overload of separate measurement gadgets offered for people to be carried around them to measure performance.Their vision is that in the future they do not need to carry separate performance wearable gadgets with us anymore while for example exercising. Instead, the measurement technology will be integrated directly into those sporting products, such as shoes or gloves, that they all are using when training anyway.They decided to start building this new era of wearables. On their view, most product manufacturer companies will also evidently become IOT-product manufacturers in the future.
