Audio Waveform Zoom and Pan for Voicemail Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small touch screens on mobile communication devices, such as cell phones and PDAs, face challenges in displaying and manipulating voicemail information due to limited size, leading to accidental selection of undesired information.
Innovation Solution
The system allows users to zoom in on and manipulate audio waveforms associated with voicemails on a touch screen, providing a full-screen view and audible feedback, enabling precise interaction with voicemail information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the touch screen size is reduced to fit mobile devices, then the device portability is improved, but the ease of manipulating voicemail information deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional static display to a three-dimensional interactive experience by enabling zooming and panning of audio waveforms. Users can pinch to zoom in/out and swipe to pan across the waveform, adding depth and spatial manipulation dimensions to the interaction, thereby making small screens as effective as large ones for detailed audio manipulation.
Solution Approach 2:
The patent makes the display content dynamic and adjustable rather than static. The audio waveform can be zoomed in and out, panned left and right, and rotated, allowing the interface to adapt to user needs. This dynamic behavior enables detailed manipulation of voicemail information on small screens without being constrained by fixed display dimensions.
2Quantity of substance
If voicemail information is displayed in close proximity on small touch screens, then the information density is improved, but the measurement precision of user selection deteriorates
Solution Approach 1:
By enabling zooming, the patent adds a scale dimension to the display. Users can pinch to zoom in on specific portions of the audio waveform, effectively increasing the display resolution for selected areas. This allows precise selection of individual audio events or time points even when multiple voicemails are displayed in close proximity.
Solution Approach 2:
The patent applies local quality enhancement through selective zooming. When a user pinches to zoom on a specific portion of the waveform, that local area is enlarged with higher visual detail while other areas remain at normal scale. This localized enhancement allows precise manipulation of specific audio events without requiring the entire screen to be enlarged.
3Volume of moving object
If the touch screen size is reduced, then the device compactness is improved, but the visual accuracy of audio waveform manipulation deteriorates
Solution Approach 1:
The patent implements dynamic scaling of the audio waveform through zoom operations. Users can pinch to zoom in to see fine details of the waveform with high visual accuracy, then zoom out to see the overall structure. This dynamic adjustment of scale allows the display to provide both macro and micro views, maintaining visual accuracy regardless of the small physical screen size.
Solution Approach 2:
By introducing zoom as an additional interaction dimension, the patent effectively creates multiple display scales on a single small screen. The ability to zoom in provides a magnified view that compensates for the limited physical resolution, allowing users to see audio waveform details with the same visual accuracy as on a larger screen.
4Ease of operation
If users interact with audio waveforms on small touch screens, then the ease of operation is improved, but the time required for manipulation increases
Solution Approach 1:
The patent uses periodic gesture sequences for efficient manipulation. Users perform repeated pinch-to-zoom and swipe-to-pan gestures to navigate and analyze audio waveforms. These periodic, rhythmic interactions become intuitive and efficient, allowing users to quickly scan through voicemails by repeatedly zooming and panning without requiring complex or time-consuming operations.
Solution Approach 2:
The dynamic zoom and pan capabilities allow users to quickly navigate to areas of interest and then zoom in for detailed examination. This dynamic adjustment of view scale enables efficient information gathering by allowing users to sweep through content at a glance and then focus on specific details only when needed, reducing overall manipulation time.

AI summary
A mobile communication device displays, via a display, an audio waveform associated with a voicemail received by the mobile communication device, and receives selection and sustained contact with the audio waveform from a user associated with the mobile communication device. The device also enlarges a portion of the audio waveform based on the sustained contact with the audio waveform, and displays, via the display, the enlarged portion of the audio waveform. The device further enables the user to manipulate, via the display, the enlarged portion of the audio waveform, and provides, via a speaker, audible feedback associated with the manipulated enlarged portion of the audio waveform.
