Tesseract 3-Dimensional pointing device for virtual spaces - PowerPoint PPT Presentation

Tesseract— 3-Dimensional pointing device for virtual spaces Jayasurya Salem Sudakaran (956569) with Prof. Michael Kipp Interaction Engineering Winter semester 2019/2020 Augsburg University of Applied Sciences

COMPONENTS Frame — Hollow cube, provides structure for the device Ball — Controller, moves within the frame in 3D space Elastic suspensions — Pulls back the ball into place, zero Rei-bung! matchbox — Marker for the phone to track

3D physical input — 2D virtual context 6 degrees of freedom — Translation and rotation* in X-Y-Z axes

RATE-BASED MAPPING 0.1cm x conversionFactor 0.1cm with clutch

RATE-BASED MAPPING 0.1cm x conversionFactor 0.1cm with clutch 0.1cm/sec x 3sec x conversionFactor 0.1cm for 3sec Distance as rate of movement and time as multiplier Ex: Gas pedal

AN EXISTING SOLUTION 3Dconnexion space mouse Blue and red are not in equal space as green

TRACKING Tracks movement of marker in 3D space relative to center of cube as zero

TRACKING Tracks movement of marker in 3D space Unity for 3D position tracking relative to center of cube as zero Vuforia is an Augmented Reality library that tracks any predefined marker
