Pressure-Sensitive Input Unit for Object Execution with Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file execution methods in electronic devices limit user recognition of object attributes by relying solely on visual representations and uniform input behaviors, failing to provide attribute information in alternative sensory modalities and adapt input behaviors based on object attributes.
Innovation Solution
An object execution apparatus and method that utilize a display unit, input unit, and control unit to detect object selection, determine attribute-specific pressure values, and execute objects based on input pressure levels, providing haptic feedback indicative of attribute information through vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual representations and uniform input behaviors are used for all objects, then the device complexity is reduced and ease of operation is improved, but the user's recognition of object attributes is limited and information loss occurs
Solution Approach 1:
The patent assigns different pressure threshold values to different objects based on their attributes. Each object has a locally optimized pressure requirement that reflects its specific characteristics, allowing the system to convey attribute information through varying haptic feedback without requiring complex visual displays or multiple input devices.
Solution Approach 2:
The system changes the pressure parameter threshold dynamically based on object attributes. By adjusting the pressure threshold value associated with each object, the system encodes attribute information in a physical parameter that the user can感知 through haptic feedback, thereby reducing information loss without increasing device complexity.
2Loss of information
If haptic feedback with attribute-specific pressure values is implemented, then user recognition of object attributes is enhanced and information loss is reduced, but the ease of operation decreases due to differentiated input behaviors
Solution Approach 1:
The system allows objects to effectively communicate their own attributes through haptic feedback. When a user touches an object, the device provides pressure threshold information that helps the user understand the object's attributes and determine the appropriate input force, making the interaction more intuitive and self-guiding.
3Loss of information
If pressure-sensitive input is used to convey attribute information, then alternative sensory modality is provided and information loss is reduced, but the device complexity increases due to pressure sensing requirements
Solution Approach 1:
The touch screen serves multiple functions: it acts as both the display interface and the pressure sensing input device. By integrating the pressure sensing capability into the existing touch screen, the system avoids adding separate complex sensing hardware while still providing haptic feedback and attribute information through pressure threshold variations.

AI summary
An object execution method and apparatus is provided for executing an object based on an input pressure level with a haptic feedback indicative of an attribute of the object. An object execution apparatus may include a display unit, an input unit, and a control unit. The display unit may display at least one object. The input unit may detect a selection of an object and/or a pressure level input for executing the object. The control unit may check a reference pressure value preset for the selected object. The reference pressure value may be indicative of attribute information of the object. The control unit may compare an input pressure value of the pressure level input with the reference pressure value, and may determine whether to execute the object based on the comparison result. The input unit comprising a vibration generator may generate a vibration mapped to the reference pressure value.
