Embodiment Construction

[0051] figure 1 The interactive system 1 is shown in. The interactive system includes a surface 2 with a limited range, and an object 3 can be placed on the surface either in contact with the surface 2 or in close proximity to the surface 2. in spite of figure 1 It is not shown in further detail in, but in some embodiments, surface 2 covers the screen of the display device. In other embodiments, surface 2 is patterned as a board game surface. In this example, the surface 2 is rectangular, but in other embodiments, the surface has another simple connected shape, such as a convex shape.

[0052] The interactive system 1 has the ability to position an object 3 and any other objects (not shown) on the surface 2. In some embodiments, the system 1 is equipped with logic to infer the input signal from the position of the object 2. In these embodiments, the interactive system 1 functions as a touch screen. In this regard, it can be noted that although the object 2 in the example shown ...

Abstract

A method of locating an object (3;42) placed on a surface (2:24) includes identifying normally clear lines of sight blocked by the object (3:42) by evaluating responses of the receivers of at least some of pairs of a transmitter and a receiver able to detect a signal from the transmitter. At least one element of one of the pairs of which the response of the receiver is evaluated is included in a further object (6;32), which is movable across the surface (2;24).

Description

Technical field [0001] The invention relates to a method for positioning an object placed on a surface, and a system for positioning an object placed on a surface. The invention also relates to an object movably arranged on or above the surface, and a computer program. Background technique [0002] WO 2006 / 095320 discloses a method for detecting the position, shape and size of at least one object placed on a plane within the boundary of a touch sensor of a touch screen. The touch screen display includes N light emitters and M sensors on its periphery. The method generally consists of the following two phases: calibration phase and working phase. During the calibration phase, when each light emitter is switched on within its respective on time, the projected beam can be detected by some sensors. For each light emitter, the identification of the sensor that detects the light beam of each light emitter is recorded as calibration data. When there is an object, non-calibration data is...
