A Haptic Warning Device with Radio Frequency Identification

A haptic warning device with radio frequency identification (RFID) is disclosed. The haptic device determines the distance between the user and a RFID device and accordingly warns the user.

Disclosed is a haptic warning device with radio frequency identification (RFID). The haptic device interacts with Radio-Frequency Identification Systems (RFIDs) such as RFID transmitters and receivers and warns a user about dangerous locations or areas to which the user is approaching. As the user approaches a RFID marked area, the warning or feedback intensity increases.

In a scenario, the haptic device is utilized by visually impaired users. The visually impaired users use the haptic device with existing RFID reader applications, such as, but not limited to, crosswalk signals, to provide a non-audio feedback.

In another scenario, the haptic device is utilized by hearing impaired users. In such a scenario, the haptic device warns the users about a dangerous area in a high noise environment when sirens or alarms are inaudible.

In an exemplary scenario, the user activates a personal computer device, equipped with a haptic attachment or extension and a Radio Frequency Identification (RFID) receiver. The RFID receiver detects active or passive RFID signals from nearby transmitters and provides interactive feedback to the user based on corresponding program logic.

In another exemplary scenario, the user is made aware of the boundaries of a stage or raised platform by detecting RFID signals from an RFID caution tape of the stage wherein the caution tape represents edges of the stage.

In another scenario, a stage performer utilizes a leg strap comprising the haptic device and a miniature receiver which are connected to a computer. When the performer approaches near the edges of the stage, the haptic device is activated. After activation, the haptic device provides feedback based on distance between the performer and the edges of the stage.

In yet another scenario, users foresee an integrated city with haptic devices such as, but not limited to, variable phone vibration as a potential alternative to separate haptic extension. In yet another scenario, the haptic device is used for monitoring traffic lights and helping users to walk on roads.
