Visuals and sounds and also partially touch are already being successfully implemented in our digital environment. Smell and taste are not (CampaignAsia, 2015). Even though they would be the key senses to create the most emotional responses as they are the only two senses that are directly linked to the limbic system of our brain. That part is mainly responsible for triggering emotions, evoking certain memories and even for making decisions (AdrianCheok, 2016).

Our future might contain E-lollies, smellable alarm clocks and programmed dinner. Professor David Cheok works on some of those inventive new ideas:

  • Flavoured Environments
    Quite certainly, companies and employees will make us of odors to create a scenting environment. This can increase the intensity of work.
    Furthermore, smell implementation in urban environments is expected to motivate working behaviour
  • Fictitious Food
    Weight reduction will become easier soon: Scentee – a Japanese business created a tool that may be connected to our phones. This will affect our tasting perceptions and make us think having a burger while we are actually biting into an apple.
  • Smell Messages
    Harvard Universities biomedical engineers designed “Ophone”  that will enable us to create “smell messages” (AdrianCheok, 2016) that will be similar to our common text messages.
  • Programmed Dinner
    Adrian Cheok is convinced that soon we will have the opportunity to select our meals similar to how we do with music programs.
  • Wake up and smell the bacon
    Already available on iTunes store, the Most Creative Use of Technology prize winning app “Wake up and smell the bacon” allows to set an alarm clock in a unique way: Instead of annoying alarm sounds, the crackling of bacon fried in a pan rouses users from their sleeps. Additionally, an obtainable tool spreads the scent of bacon to gently awake you. That sounds like a more gentle and appetizing way of ending the sleep time which is already unpleasant enough.baconalarm

  • E-lollies
    First spotted at the Cravings exhibition at Science Museum, the E-lolly provides a stunning new experience.Fig. 4

    Please klick on the link above – unfortunately the video is not available on youtube but highly interesting to see how the tongue, our taste perception and the e-lolly work.
