We introduce Silent Rider, a visual-tactile messaging interface that aims to facilitate a hearing-impaired deliverer’s mobile phone communication with their customers.  Silent Rider augments a typical smartwatch interface with a virtual module that interchanges users’ different input modalities. A customer’s speech is converted into tactons for a user with profound hearing loss to understand, while the corresponding user can make voice output through customized messaging functions. To implement this interface, we first identify design requirement, then we present the system workflow and designed functionality. Lastly, we make a discussion on future design opportunities to help hearing impaired people communicate in the workplace.
