A new high tech mirror，designed specifically for cancer patients，will only become reflective when a user smiles into it.The plug-in device，which exactly looks like a tablet，comes equipped with a mirror，a built-in camera，and a smart material triggered(触发)by some software.Facial recognition technology captures the face and instructs the surface of the mirror to change when a smile is detected.It can hang on a wall or sit on a table，much like a conventional mirror.Unlike a regular mirror，however，the price is currently standing at a surprising $2000—$3000.

After witnessing a close family member struggle through cancer treatments，Turkish industrial designer Berk Ilhan decided to focus his work primarily on products that would cultivate joy and benefit cancer patients directly.

“She told me in the first days after her diagnosis，it was difficult for her to look in the mirror and acknowledge she had cancer.”he said.“Our facial expressions affect how we feel.If we flex(绷紧)our facial muscles to smile，our brains think that something good happened and as a result，we feel happiness.”

After earning his master’s degree at the School of Visual Arts in New York，Ilhan spent several weeks visiting cancer hospitals in Turkey，speaking to both patients and doctors.He spent two years designing and developing the mirror.The idea behind it is that smiling，even when forced，can make us feel better，according to research known as the facial feedback hypothesis.Laughter is linked to improved immune system function，and some researchers claim it can even increase our lifespans.

Ilhan is currently producing the mirror in limited quantities at the previously mentioned price.The product，however，will soon be launching a campaign in which Ilhan hopes to raise enough funds to bring the price down to $500.He also intends to donate the mirror to hospitals when it is financially possible to do so.
