Balloon Help, which is becoming standard in the Macintosh world, enables the user to display brief annotations of interface objects by passing the pointer (cursor) over those objects. This investigation explains the operation of Balloon Help, presents the theoretical and empirical rationale for Balloon Help, assesses its value in supporting both exploration of an interface and task-focused behavior, considers its relationship with other forms of help, and evaluates some possible modifications of Balloon Help. Balloon Help is viewed as a successful implementation of minimalist principles that nevertheless needs to be supplemented by other forms of documentation.
