Towards a disambiguation canvas

摘要: We present Disambiguation canvas, a technique for selection by progressive refinement using mobile device and consisting of two steps. During the first, user defines subset objects through orientation sensors volume-casting pointing technique. The subsequent step consists disambiguation desired target among previously-defined objects, is accomplished touchscreen. By relying on touchscreen last can disambiguate hundreds at once, previous techniques do not scale as well ours. canvas mainly developed easy, accurate fast small or inside cluttered virtual environments. User tests show that our performs faster than ray-casting targets with ≈ 0.53° angular size, also much more all tested sizes.
