Jenny Vuong, Benedetta Frida Baldi, Christopher Hammang, Seán I. O'Donoghue (384 Victoria Street)Advances in web-based 3D graphics are making 3D datasets more accessible to a rapidly growing community of users. A key challenge common to almost all 3D applications is onboarding, since the standard methods used for 3D controls (e.g., rotate, translate, zoom, etc.) can be difficult for new users to learn. Another key challenge is depth cueing. Both challenges can be partly addressed using dedicated control devices, such as a 3D wand; however for web applications, it is generally best to avoid depending on the availability of such devices. Thus we propose Dexterity, a prototype framework that allows a smartphone to be used as a 3D wand to control 3D objects. Given the wide availability of smartphones, Dexterity thus provides a generic solution that helps address the challenges of onboarding and depth perception.
