Current feedback is not helping reduce

prople’s sense of uncertainty, people

rather feel annoyed and impatient when

seeing all cars are busy on high floors

Effective feedback to give people sense of certainty and deduce awareness of waiting time• Long term display so that people know that they have entered their destination successfully.

• Color coding

• Switch of attention

A more pleasing space• Currently cold and boring

• Textiles, color or lights
