This paper presents a new system for non-visual navigation of tables located within a spreadsheet. The purpose is to provide a novel hierarchical non-visual navigation of tabular structures. The hierarchical view of the spreadsheet content, along with the user ability to select the desired table within a complex spreadsheet, provides greater flexibility than what offered by current assistive technologies. The proposed system allows the user to select a table and choose between different navigation strategies. The proposed approach introduces the solution in two stages: (i) table detection and recognition and (ii) non-visual navigation of the selected table. The system is provided as a plug-in for MS Excel?.
