This hot plate from IKEA Taiwan beautifully deals with the phone at dinner distraction problem. The kitchen gadget requires at least one smartphone to be stored underneath for it to turn on. The idea is everyone around the table will place their mobile devices in the designated area so they can enjoy their meal -- and each other's company -- tech free. The hot plate holds a pot that won't properly heat up and cook the contents within (vegetables, soups, meats) with just one phone, so more will be needed.
The consumer experiment speaks to a larger concern in society that led to what some refer to as the 'digital detox' movement. The phone at dinner perfectly symbolizes the loss of human connection resulting from the influx of technology in our lives.
