Data collection covers both indoor and outdoor environments, including offices, meeting rooms, parking lots, gardens, and other common work and daily-life scenarios. Lighting conditions include normal lighting, low-light, and backlit scenarios commonly encountered in real-world settings. Twenty video clips per participant, with each clip corresponding to the presentation of a single object and accompanied by three close-up images of the object from different angles. The subject appears in upper-body or full-body views, holding one object with one or both hands, recorded in standing or seated postures. The object is moved according to predefined actions. Each video clip includes a brief verbal description of the object provided by the model. The subject is clearly visible, and the face is not occluded for extended periods during recording.
