Electronic Bus Shelters in Barcelona

I had the opportunity to visit Barcelona for the first time this summer for a symposium but managed to squeeze in one day for a bit of exploration in the city before leaving. One of the things that caught my eyes was the electronic bus shelter. I had never seen one like this before. It's basically a shelter equipped with an electronic system designed to inform people about the waiting time for their bus. Practical, isn't it? 

I hope this means that we're getting closer to being able to use more advance systems such as the EyeStops designed by the SENSEable City Lab of MIT because I would love to be able to use them. They are essentially giant glass ipads connected to the internet and capable of providing additional information and enabling users to interact with the system and with one another through the system. I had blogged about it a couple years back on MoOt , but I haven't seen anything about it since. I wonder how long it will take to get these here in Toronto.
