BlenderGaze

The BlenderGaze dataset is specifically created to further investigate Visual Perspective Taking (VPT) in Vision Language Models (VLMs). This dataset extends the previously introduced Isle dataset, primarily expanding in terms of size rather than diversity.

BlenderGaze consists of two complementary subsets:

• BlenderGaze-Isolated: Contains isolated scenes featuring a humanoid figure and a red box. These scenes are explicitly designed to isolate and test the basic VPT capabilities of models (see Figure 1).

• BlenderGaze-Texture: Includes more complex and realistic scenes with 10 distinct backgrounds, each featuring 256 unique scenarios involving interactions between humanoids and robots. This subset aims to explore VPT within human-robot interaction scenarios.

In both subsets, objects are randomly placed, and camera viewpoints vary. Visibility is determined by a 120-degree field-of-view cone originating from the humanoid figure's eyes, representing human peripheral vision. Each scene is provided in two versions:

• With visual cone: The visibility cone is explicitly shown, serving as a clear indicator of the humanoid figure's perspective (ground truth).
• Without visual cone: Simulates a natural viewing experience without explicit indicators of visual perspective.

Due to the rendering process, some minor errors in ground truth annotations might occur, though such inaccuracies are expected to be under 10%.

Scene and Background Textures

The following environment textures from Poly Haven were used to generate diverse and realistic backgrounds:

• Belfast Sunset
• Christmas Photo Studio 02
• Moonlit Golf
• Park Parking
• Paul Lobe Haus
• Simon's Town Road
• Studio Country Hall
• Floral Tent
• Orlando Stadium
• Courtyard Night

3D Models

• Robot Model: Free3D - Basic Robot
• Humanoid Model: Sketchfab - Rigged T-Pose Human Male

This dataset supports researchers and psychologists studying visual perspective taking, spatial reasoning, and scene understanding in both humans and VLMs.
