Call my attention!

“Call My Attention” is an application for immediate Line-of-Sight Signaling on Mobile Phones. The application, which proposes a mobile device function to be used like a remote control, enables ‘buzzing’ of nearby friends to achieve immediate attention.

It is especially helpful for deaf or hard-of-hearing users, but also generally in loud and crowded environments.

It results from the Project “DESIGNABILITIES – Disability-inspired Interaction”. Main goal of this project is to find ways for enhancing Human-Computer-Interaction (HCI) and Information-Communication-Technology (ICT) by transferring properties and principles from ‘disability’ context into general contexts of communication.

Therefore we investigate on alternative interaction techniques inspired e.g. by deaf communication or blind navigation.
