Unity Scene Setup and AOI Configuration

I need someone to set up a scene in Unity and configure the AOI (area of interest) for a VR headset. I already have this Unity Asset Store scene: Padel Tennis Court - Sports Ground. I do not need the sports venue to be modelled from scratch. What I need is for you to adapt this existing Unity scene into a ready-to-run VR eye-tracking experiment. The task would include placing sponsor banners/posters in predefined locations, creating several experimental conditions (same scene but different posters), showing instructions in the headset, recording gaze/AOI data, and exporting the results to CSV. I already have the Unity Asset Store asset “Padel Tennis Court - Sports Ground”. I need a complete ready-to-run VR eye-tracking experiment, not just a prepared scene. The final deliverable must allow me to run the experiment directly on my computer with the VR headset and obtain the attention data files automatically. Expected deliverables: 1. Complete Unity project * The padel court asset imported, configured and fully working. * Scene correctly prepared for VR. * Materials, lighting and scale checked. * The project must be clean and organised so I can reopen it later. 2. Working executable/build * A ready-to-run build for the selected headset/platform. * The experiment must run directly from my computer. * The headset must display the padel court scene correctly. * The participant must start from a fixed predefined position and orientation. * The participant should be able to look around naturally in VR. 3. Eye-tracking integration * The application must record gaze data from the selected headset. * Gaze recording must start automatically when the scene begins. * Gaze recording must stop automatically when the exposure ends. * The system must save the data without requiring manual coding from me. 4. Attention indicators / database The system must export a CSV or Excel-compatible database including, at minimum: * participant_id * session_id * timestamp * hit_object * aoi_name * aoi_hit * dwell_time_ms per AOI * total viewing time * time_to_first_fixation_ms per AOI, if technically feasible * fixation_count per AOI, if technically feasible * total_fixation_duration_ms per AOI, if technically feasible * revisit_count per AOI, if technically feasible 5. AOI system * The scene must include predefined AOIs. * AOI names must appear clearly in the exported database. * I must be able to identify which areas attracted attention and for how long. 6. Experimental flow * Start screen or participant ID input. * In-headset instructions. * Fixed exposure to the VR scene. * Automatic end screen. * Automatic data export at the end of each participant/session. 7. Documentation Please include a short user guide explaining: * how to open the Unity project; * how to run the executable; * how to connect/use the headset; * how to start a participant session; * where the data files are saved; * what each variable in the database means; * how to verify that eye tracking is working. Please estimate the total price and timeline assuming that the 3D environment is already provided.
