Portable electronic information collection and presentation device

摘要

A golfer's electronic assistant device (10) provides a touch screen (18) on a core module (12) with removable side modules (14, 16) powering the core module (12) and supplying functional expansions. A modular dock (50) in the core module receives essential equipment modules such as a global positioning system. The touch screen (18) shows graphical representations of each golf hole, the golfer's present position, and accurate distances to the pin, fairway hazards, and landmarks. Each round is timed, and data for scoring and other statistics is entered, stored in a database, and analyzed to produce an output of data personalized to the golfer's characteristics. The output may provide current golf handicap, and situational tips such as a recommended club selection for any situation based on prior performance, global positioning data, and total score.
