Touchscreen Manipulable Object Holder for Tilted-Surface Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen interaction technologies, such as those described in US2006256090 A1 and EP2187290 A1, fail to allow for flexible actuator implementation across different applications and orientations, leading to interaction errors when the touch surface is tilted or vertical, and translational movements during rotational interactions.
Innovation Solution
A system comprising a support for manipulable objects with lugs and slots that maintain interaction with the touch surface regardless of orientation, using a slot width greater than or equal to the support thickness to ensure continuous contact, and a notch to prevent lateral slippage, allowing for precise interactions including rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent mechanical layer with actuators is implemented on the touch surface, then the actuator implementation is fixed and stable, but the user cannot utilize the full touch surface across different applications and cannot change the actuator depending on the application
Solution Approach 1:
The patent divides the touch surface into multiple zones: a first zone with a mechanical layer containing actuators, and a second zone without the mechanical layer. This segmentation allows different interaction modes in different regions, enabling both stable actuator implementation in the first zone and full touch surface utilization in the second zone across various applications.
2Device complexity
If the cursor is guided along a fixed axis on a tilted or vertical touch surface, then the guidance mechanism is simple, but the cursor will not remain in contact with the touch surface at its upper edge, resulting in interaction errors
Solution Approach 1:
The patent makes the cursor guidance dynamic by allowing the cursor to move along an axis that is not fixed relative to the touch surface orientation. The guidance mechanism adapts to the touch surface angle, maintaining cursor contact with the touch surface regardless of whether it is horizontal, tilted, or vertical, thus preventing interaction errors.
3Ease of operation
If a game piece is used for rotational interaction on a touch screen, then rotational control is enabled, but the piece slides across the screen during rotation, leading to interaction errors
Solution Approach 1:
The patent introduces a cursor as an intermediary element between the user's rotational input and the touch screen interface. The cursor is guided along a constrained path (such as a circular arc or chord) that corresponds to the rotational gesture, translating the rotation into precise interface control without the physical piece sliding across the screen.
4Stability of the object's composition
If a button with suction cup is used to fix position on touchscreen, then translational movement is prevented, but the button slides across the screen when touchscreen is positioned other than horizontally, leading to interaction errors
Solution Approach 1:
The patent makes the button's interaction dynamic by allowing the contact point between the button and touch screen to change based on the device orientation. The button is designed to maintain contact with the touch surface through its lower edge or specific contact region, adapting to horizontal, tilted, or vertical positions without sliding, thus ensuring interaction accuracy across all orientations.

AI summary
The invention relates to objects that can be manipulated relative to a touch-sensitive surface, in particular game pieces or buttons for interacting with a touch screen. A manipulable object according to the invention is a manipulable object comprising: · at least one lug enabling an interaction with the touch-sensitive surface, and · a slot suitable for inserting the manipulable object on a holder that can be positioned relative to the touch-sensitive surface, the placement of the slot over the height of the manipulable object being suitable for keeping the at least one lug of the manipulable object in interaction with the touch-sensitive surface. Thus, the manipulable object allows the touch-sensitive surface to be interacted with at any time without any interaction errors, regardless of the position of this touch-sensitive surface relative to the horizontal: the touch-sensitive surface identifies any interaction (at a point or sliding) of the manipulable object and a non-erroneous location of this interaction on the tactile surface.
