I recommend you to refer a project TeleAbsence from MIT Media Lab.
The purpose of Telepresence is to connect people who are alive. TeleAbsence aims to create illusionary communication channels with those no longer with us to soothe the pain of bereavement . TeleAbsence is designed around tangible objects, such as old typewriters, telephones, brushes, and pianos that were once touched and marked by the hand of a loved one.
