Haptic navigation device

A navigation device comprising:

• a housing comprising an opening, two or more drive wheels, and two or more rollers, wherein the two or more drive wheels and the two or more rollers are all arranged in a single plane;
• a spherical member located within the opening of the housing in direct contact with the two or more drive wheels and the two or more rollers such that the drive wheels control rotation of the spherical member in response to guidance signals received from a processor, wherein an axis of rotation of the spherical member is perpendicular to a direction of travel indicated by a navigation message;
• and
• an attachable member coupled directly to the housing for securing the navigation device to a body part of a user and maintaining contact between the user's skin and the spherical member.

A method comprising:

• receiving, by a haptic navigation device worn by a user, a navigation message from a remote device;
• determining a geographical location of the user from a global positioning unit of the haptic navigation device;
• determining a orientation of the haptic navigation device from a gyroscope integrated into the haptic navigation device;
• calculating a guidance signal based on the received navigation message, the geographical location of the user, and the orientation of the haptic navigation device;
• and
• sending the guidance signal to two or more motors causing a spherical member of the haptic navigation device to rotate, wherein the rotation of the spherical member corresponds to the received navigation message.
