Building the Perfect Trackpad Click

As Windows 11 will offer haptic trackpad configurations, OEMs spent a lot of time trying to achieve the perfect trackpad. The sensation we experience influences our subconscious to like or dislike our device. A simple click can drastically alter our impression of the product itself.

However, no study gives us the parameters of a perfect click. The ideal click feeling is highly subjective. One may prefer a more powerful click, while another will prefer a softer click. The human brain needs to detect a jolt at the level of the finger to feel a click. The force variation, waveform shapes, and mechanical integration level will affect the user experience. Besides, sound helps our brain understand that the click has taken place. The sound level needs to be aligned with the trackpad haptic effect's force.

Therefore, Boréas work closely with OEMs to tailor the trackpad module according to customer-preferred click feeling. We believe that every OEM will have its custom piezo haptic trackpad in the future to create the perfect click. (Read Full Article)
