So, in the central room we have a sink, with an electric dryer, electric dryers were invented prior to 1930. The first was in 1921, but were used in public locations, smaller versions as seen here were not popularised until 1948. The room was centred around a single table, that included a hologram showing who is at the door, we’ve not reached that point even today and the film struggled to convey it then. Although television is not explicitly mentioned or shown, a flat screen is present above the fireplace, which seems to be used almost exclusively for 2 way video communication, but more on that later.

 

Finally we have the doors, which obviously slide. Sliding doors have been around since Roman times, but combining them with automation didn’t come along until 1954, when Dee Horton and Lew Hewitt perfected the concept. However dispite being a common peice of future design from H.G. Wells ‘When the sleeper Wakes’ to the 1966 Star Trek, automated sliding doors have remained focused on business and retail entrances and are seldom used in the design of residential properties.
