A structured description is generated for a digital image of a scene. The structured description may include a first feature and a second feature of the scene. The structured description may also include a first detail of the first feature and a second detail of the second feature. A portable braille sequence printer may generate braille text of the first and second features using the structured description. The portable braille sequence printer may further generate additional braille text regarding the first detail in response to a prompt from the user regarding the first feature.
