Kyocera Integrates HAPTIVITY® Technology into Sigma BF Mirrorless Camera

KYOTO, Japan--(BUSINESS WIRE)--Apr 22, 2025--

Kyocera Corporation (President: Hideo Tanimoto; “Kyocera”) announced today that HAPTIVITY ®, its proprietary tactile technology that replicates realistic touch sensations, has been integrated into the Sigma BF, a full-size mirrorless camera to be released this month. This is the first application of HAPTIVITY ® in a mirrorless camera.

HAPTIVITY® is a groundbreaking technology that harnesses Kyocera’s piezoelectric ceramic vibrating elements to create truly immersive tactile sensations. Biomechanically engineered vibration waveforms provide tactile feedback by stimulating neural receptors in the user’s fingertip, providing physical verification when a button is depressed and released — or even simulating the feel of a physical button where none exists.

Kyocera’s HAPTIVITY® technology integrates seamlessly into Sigma BF’s three recessed rear buttons (Function Dial, Options, and Playback — including the dial’s up, down, left, and right touchpoints), for accurate, comfortable, intuitive operation. Haptic feedback ensures reliable performance by enhancing user confidence and avoiding duplicate commands.

Kyocera envisions a future where HAPTIVITY® becomes a ubiquitous, high-performance tactile technology. With its piezoelectric ceramic vibrating elements, HAPTIVITY® has the potential to revolutionize consumer and automotive applications as an essential component of the next-generation human-machine interface. It can improve the user experience for any device having physical buttons, or having screens and panels designed to provide tactile feedback.

*HAPTIVITY is a registered trademark of Kyocera Corporation. Kyocera's patented tactile transmission technology optimally controls pressure detection, reproduction of the feeling of pressing a mechanical button, and vibration activation using a combination of piezoelectric elements, vibration amplification mechanisms, control circuits, and software.

Features of HAPTIVITY ®

1. Excellent vibration response

HAPTIVITY® uses a piezoelectric ceramic vibrating element with excellent touch-response, delivering physical feedback that instantly confirms user input and eliminates duplicate commands.

2. Realistic tactile feeling

A mechanical button delivers two sensations: on press, and on release. Conventional tactile technology generates a single sensation (when pressed), which differs from the tactile feeling of a button. In contrast, HAPTIVITY® generates an initial vibration when pressed, and a second vibration when released, providing a more realistic button sensation.

3. Tactile confirmation improves operation

Immediate tactile feedback confirms user input instantly, ensuring reliable operation and eliminating ambiguity. This makes HAPTIVITY® ideal for demanding applications, including mobility, telemedicine, and industrial equipment.

4. Recessed buttons save space, increasing design freedom

HAPTIVITY® facilitates compact, thin, flat designs, allowing recessed buttons that promote space-saving and greater freedom of design.

LOS ANGELES (AP) — Giannis Antetokounmpo blocked a shot by LeBron James and stole the ball from him on consecutive possessions in the final minute, and the Milwaukee Bucks blew a fourth-quarter lead before rallying for a 105-101 victory over the Los Angeles Lakers on Friday night.

Kevin Porter Jr. scored 22 points, and he hit two free throws to break a tie after Antetokounmpo blocked a driving layup attempt by James with 39 seconds left.

Antetokounmpo then knocked the ball out of James' hands from behind with 2 seconds left, and Porter hit two more free throws to seal Milwaukee's fifth win in seven games — its first over a team with a winning record since Dec. 11. Antetokounmpo finished with 21 points in his lowest-scoring effort since returning from his right calf strain.

Luka Doncic had 24 points and nine assists on 8-of-25 shooting for the Lakers. He had his lowest-scoring performance since Christmas, and he fouled out on Porter's 3-point attempt with 16.2 seconds to play.

James had 26 points, 10 assists and nine rebounds, but Antetokoumpo got the best of the top scorer in NBA history at crunch time. Los Angeles has lost six of 10.

Milwaukee surged to a double-digit lead in the first half even with Antetokounmpo on a minutes restriction in his injury return. Doncic scored 12 points in the third quarter but also committed four fouls in the period, including his fifth of the game.

Los Angeles abruptly erased its deficit by going on a 17-4 run to open the fourth, with James putting the Lakers ahead when he stole the ball from Antetokounmpo for a layup with 6:02 left. Milwaukee missed nine of its first 12 shots in the period, but Porter's layup tied it with two minutes left.

Lakers starters Austin Reaves and Rui Hachimura remain sidelined by injury, but Hachimura (calf) might return early next week from his six-game absence, coach JJ Redick said.

Bucks: At Denver on Sunday.

Lakers: At Sacramento on Monday.
