TF-Shell: Facilitating Physical Deformation with Iterative and Shape Memory Thermoforming for 3D Printing

Prototyping with 3D printing depends heavily on virtual modeling, which requires expertise and often leads to scale mismatches and inefficient iteration. Physical deformation through heating is possible but challenging, as heating is difficult to control and deformation remains complex. We introduce TF-Shell, a thermo…

Typing Haptically: Towards Enabling Non-auditory Smartphone Text Entry with Haptic Feedback for Blind and Low Vision Users

Text entry on smartphones remains challenging for Blind and Low Vision (BLV) users, particularly in environments where audio feedback is impractical due to noise, privacy, or social stigma. We present TypeHap, a new system that enables BLV users to type confidently on smartphones using only haptic feedback without rel…

StringTouch: A Non-occlusive 3DoF Haptic Interface Using String Structures for Modulating Finger Sensations

Providing realistic and diverse tactile feedback during interactions with objects in virtual and augmented reality, various studies have explored the use of tangible proxies. However, tangible proxies face limitations due to their fixed physical properties, restricting the expression of various stiffness, weights, and…

Designing Metamaterial Cells to Enrich Thermoforming 3D Printed Objects for Post-Print Modification

In this paper, we present a metamaterial structure called thermoformable cells, TF-Cells, to enrich thermoforming for post-print modification. So far, thermoforming is limitedly applied for modifying a 3D printed object due to its low thermal conductivity. TF-Cells consists of beam arrays that affluently pass hot air…
